urinals

Why No One Talks About Urinals Anymore

URINALS AIN’T NO ONE’S FRIEND

URINAL CLEANING DONE RIGHT

 

In every commercial restroom in the world you’ll find a urinal, at least in the men’s room anyway. With all that’s going on in the world, that could actually be a very bad thing. Check out this article from the Chicago Sun Times. Something to think about the next time you enter the men’s room.

Wearing a mask in public restrooms should be mandatory during the pandemic, researchers say, because there’s increasing evidence that flushing toilets – and now urinals – can release inhalable coronavirus particles into the air.

The coronavirus can be found in a person’s urine or stool, and flushing urinals can generate an “alarming upward flow” of particles that “travel faster and fly farther” than particles from a toilet flush, according to a study published in the journal Physics of Fluid Monday.

“Urinal flushing indeed promotes the spread of bacteria and viruses,” researcher Xiangdong Liu said in a press release. “Wearing a mask should be mandatory within public restrooms during the pandemic, and anti-diffusion improvements are urgently needed to prevent the spread of COVID-19.”

Liu and other researchers from Yangzhou University in China simulated urinal flushing using computer models and estimated that, within just five seconds of flushing, virus particles could reach a height of more than 2 feet off the ground.

“Potentially, it could contaminate other surfaces you would touch – the handle, the tap,” said Charles Gerba, a professor of virology at the University of Arizona. “The concern is also – was there anything left over from the person who was there before? Aerosolization from the previous user you may potentially inhale?”

Some of the same researchers released similar findings in June, focused on toilet flushing. Through another computer model, the researchers found that thousands of particles can come out of the toilet within 70 seconds of flushing, and that some can reach higher than a foot above the toilet bowl in half that time.

“It is reasonable to assume that the high-speed airflow will expel aerosol particles from the bowl to regions high in the air above the toilet, allowing viruses to spread indoors causing risks to human health,” the researchers said at the time.

The studies are interesting but unsurprising, as research on particles kicked up in “toilet plumes” has been around for about two decades now, said Joshua Santarpia, a professor of pathology and microbiology at the University of Nebraska Medical Center specializing in bioaerosols.

“The more interesting thing to me was that I hadn’t considered the urine issue – whether SARS-CoV-2 was shed in urine,” he said.

Coronavirus found in urine, stool

Many people aren’t aware that toilets and urinals can release particles into the air, let alone that genetic material from SARS-CoV-2 – the virus that causes the disease known as COVID-19 – can be found in patients’ urine and stool, Gerba said.

“It’s probably been overlooked – urine contamination,” Gerba said. “Smallpox, Zika virus are excreted in the urine. What’s surprising is that a respiratory virus can be excreted in the urine.”

At least two studies – one in Tokyo and one in Guangzhou, China – have found coronavirus RNA in patients’ urine. Studies published in the journals Gastroenterology and The Lancet also found coronavirus RNA in patients’ stool, even weeks after the patients showed negative results in respiratory samples. One study in and around Beijing, however, did not find any evidence of virus in 72 urine specimens.

It’s still unclear whether COVID-19 can transmit through urine and infect another person, Gerba said.

“Is there enough virus in the urine to worry about? Does enough get aerosolized? Those are questions we need to look at,” he said.

The researchers at Yangzhou University argue that transmission in a public restroom has already happened. They cite local news reports of a couple, who work at a food market in Beijing, contracting the virus at a restroom nearby.

“What’s worse, two of COVID-19 reemerging confirmed cases in Beijing have been reported to be infected from a public toilet, which practically proves the danger from the public restroom,” the researchers wrote.

Can the coronavirus disease spread through air?

Health experts believe the virus mainly transmits through respiratory droplets when someone coughs or sneezes, but the World Health Organization says that “short-range aerosol transmission . . . cannot be ruled out.”

Researchers measuring the amount of viral aerosols in different areas of two Wuhan hospitals found that while the concentration detected in isolation wards and ventilated patient rooms was very low, it was higher in the toilet areas used by the patients, according to an April study published in the journal Nature.

The researchers recommended that room ventilation, open space, sanitization of protective apparel, and proper use and disinfection of toilet areas could effectively limit the concentration of SARS-CoV-2 RNA in aerosols.

“I think there’s a lot of strategies and interventions that could be developed if it really turns out that there’s significant risk,” Gerba said.

For now, the next best step would be to put the researchers’ computer model to the test to see if flushing a urinal actually kicks virus particles up into the air, Gerba and Santarpia said.

“Somebody should really validate some of this experimentally. It’s a model, and there are a lot of assumptions,” Santarpia said. “More work needs to be done.”

6 Things Your Boss Expects You Know About Press Vs Solders

PRESS OR DIE

Rookies in Action, YouTube

The plumbing world just like everywhere else is moving at a record pace. New technologies emerge almost on a daily basis, at the forefront of these technologies are 2 companies leading the way in form and function.

RIDGID and VIEGA are those companies improving the plumbing, heating and gasfitting trade worldwide and right here in Calgary!!

Viega press fitting system solutions are designed to integrate and our preferred press tool for installing Viega systems is designed the same way. One press tool can make connections on Viega ProPress, Viega MegaPress and Viega PureFlow PEX systems, simply by changing jaw sets.

Viega has partnered with RIDGID since 1999 to offer system-matched tools for each of our engineered press fitting systems. With jaws, rings and actuators in sizes ranging from ½” to 4″, these tools can accommodate nearly every type of plumbing, heating or pipe joining project.

PRESS OR PUSH

SHARKBITE AND PROPRESS COMBINED PROPERLY

Time saving
Push fit technology has been designed to optimise time efficiency and to help ensure installers are able to work across jobs more effectively.

No tools needed for installation
Unlike press fit methods, push fit fittings require no additional tools for installation. Once cutting, measuring and deburring of the pipes has been undertaken, the actual jointing takes just seconds to complete.

Easily de-mountable
Another key benefit is that the fitting can be easily de-mounted if there has been an error in installation or removal is required. This is not as simple with press fittings, or where traditional methods are concerned.

Importantly, if removal is required, there is only minimal need for additional materials or new pipework; the installer need only remove the existing fitting with the appropriate release tool and replace with a new one providing the pipe is not damaged.

SHARKBITE USED IMPROPERLY

Its vital to the success of your job and the trade to be blunt that you understand the difference and proper applications of press, push, soldered and mechanically jointed systems. If in doubt hire a professional in the Calgary area like Baker Plumbing Inc.

Why Handymen Should Be 1 of the 7 Deadly Sins

HANDYMEN ARE THE DEVIL

Handymen are the Devil

Have you ever had problems with a handyman you hired? I got a call from a lady the other day who had problems with a handyman she had hired. She needed me to finish a job that someone else had started and she had fired because he did not know how to do the job and he had made a mess.
There are many good people in the Handyman business today but anyone with a truck and a hammer can call himself a handyman. So, what can a homeowner do to reduce the risk when hiring someone? It’s not easy, but there are several obvious steps that can be taken.

1. Ask prospective handyman if they are licensed and carry liability insurance. If they have employees or do rental properties they need to have (workers comp) coverage. Don’t take their word for it, ask to see proof. Any legit handyman will be happy to show you this documentation. Any handyman that offer excuses why it can’t be produced walk away from.

2. You can ask for a list of references but how can you check them out? They could be giving you a list of their friends. Some online rating sites are unreliable as a reference due to the ability to post bogus reviews therefore you need to check reviews from more than one source. Just because someone has a bad review does not mean they are not good. There are always two sides to a story. How they respond to a negative negative reviews speaks volumes.

3. Do a search on the internet of their name and their company. Check their social media, what kind of person is he? Does he look like someone you can trust? How many places does his business show up on the internet? Has he invested the time and money to create a web page? Is there pictures of his work?

4. Be wary of requests for a large up-front deposit. If a job requires the purchase of custom materials and a large deposit it is probably a sign that the handyman is taking on a job that is bigger than he is capable of handling or you are trying to save money by hiring a handyman rather than a general contractor. Large jobs with longer durations will have payment milestones (including the deposit) clearly outlined in the contract. Small jobs that handymen do don’t require deposits because most handymen work on an hourly basis and charge you for the time it takes.

5. Be suspicious of really low pricing. We all love a deal and for some people price is the only criteria that matters. However, low-ball pricing is a classic scam that is irresistible to many of us. It is also a sure sign something may not be right. Choosing a handyman to do a full bathroom renovation asking for trouble. A handyman can not do any electrical work or any new plumbing and he can not hire an electrician and a plumber since he is not a general contractor.
Large renovation projects require a contract with milestones and payment schedules. If everything is not spelled out in the contract the homeowner can expect to be hit with numerous “extra” material and labour costs. If your handyman does by some miracle manage to complete the work, odds are substandard materials and workmanship are what kept the cost down.

6. Do not ask for cash only deals, that is asking for problems with a handyman. Cash only with no paper trail equals no recourse for you in the event a problem arises. You want to hire a honest handyman to work in your home. If he will work for cash and be dishonest with the government what makes you think he will be honest in his dealings with you?

7. Think it over. Take the time you need to make an informed decision and you won’t have problems with a handyman you hire. If you have to sign a contract you probably should be hiring a general contractor.

IF ONLY THEY HAD LISTENED!!

At Baker, we encounter the issues created by unqualified and uninsured work almost weekly. This past week’s experience was one for the books and hence the post. This do-gooder obviously had watched dozens of YouTube videos trying to understand the complicated design he was undertaking. Unfortunately, it appears he combined several different techniques and came up with a huge pile of crap that:

  1. Doesn’t adhere to any code.
  2. Doesn’t work
  3. Needs to replaced
  4. Actually causing physical damage to the home.

Handyman Gone Wild!

 

GOING FORWARD

 

When you hire a handyman near you to help you with various tasks around the house and yard — such as outdoor cleaning, light or fixture installation, or constructing a shed — you might think of asking them to take care of your kitchen and bathroom plumbing problems as well. However, consider the following crucial factors before you go ahead.

Beware of Amateur Plumbing Work

Handymen in some states are prohibited by law from performing plumbing tasks — other than minor jobs such as installing a new faucet fixture. The main reason for this prohibition is that an amateur, incorrect, or shoddy plumbing job by someone who is not a professional plumber can be disastrous for your home. A handyman, no matter how competent he or she may be at performing other chores, probably does not have the necessary training in dealing with plumbing blockages and other problems.

This could set you up for further damage to drains, appliances, flooring, and other things in your home that need proper plumbing in order to function correctly. And to make matters worse, your insurance might not cover the damage, since it was caused by an unlicensed worker. For major jobs, such as a bathroom remodel, a good handyman should either subcontract the plumbing work to a licensed master plumber, or leave it to you to find a plumbing professional who will pull permits, successfully install the necessary components in compliance with code, and make sure that everything works.

Plumber Licensing Requirements

Licensing is another very important difference between a handyman and a plumber. Plumbers must be licensed in 46 out of the 50 states (the exceptions are Kansas, Missouri, Nebraska, New York, Pennsylvania, and Wyoming). Requirements for working as a handyman tend to be less rigorous, although a few states, such as California, do require that self-employed handymen obtain a contractor’s license.

If you want to find out more about your area’s licensing policies for handymen, enter the name of your state and an appropriate term, such as “handyman license requirements,” into an internet search engine. Doing so should bring up the website of your state government’s licensing board (the site address will end in .gov).

Training and Apprenticeship

Handymen and “real” plumbers also tend to differ a great deal in their level of professional training and education. Master plumbers must pass a rigorous examination, after completing two years of vocational school training and/or a lengthy apprenticeship, which usually lasts at least four years. Since their licensing requirements change very often, many professional plumbers also attend continuing professional education as part of their career.

While some homeowners will want to save a bit of cash by having a handyman install or fix plumbing, the plumbing job may well end up costing you more money if you need to pay a professional plumber to fix shoddy work. In most cases, it is worth investing the extra money in the first place, to hire a reliable licensed plumber for plumbing installations and repair of significant plumbing problems. This helps to ensure that you will not end up going over your budget for a costly mistake.

Insider’s guide to UV lights and COVID-19

HVAC and UV lights

At Baker Plumbing, we are always trying to find the best and most effective approaches to solve the problems presented to us by our clients. Today we were asked to address the problem of bacteria within an HVAC system. As a professional HVAC contractor in Calgary, we immediately suggested the use of a UV light source inserted directly into the supply air of the HVAC system. You can watch a quick 1 minute video of it here :

BAKER and UV light install

UV light sources have long been used by the medical profession as a solution to eliminating infectious diseases and their sources. Learn more about UV below> NYC and UV Lights

Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency of approximately 30 PHz) to 400 nm (750 THz), shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lampstanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionize atoms, it can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.

Short-wave ultraviolet light damages DNA and sterilizes surfaces with which it comes into contact. For humans, suntan and sunburn are familiar effects of exposure of the skin to UV light, along with an increased risk of skin cancer. The amount of UV light produced by the Sun means that the Earth would not be able to sustain life on dry land if most of that light were not filtered out by the atmosphere.[1] More energetic, shorter-wavelength “extreme” UV below 121 nm ionizes air so strongly that it is absorbed before it reaches the ground.[2] However, ultraviolet light (specifically, UVB) is also responsible for the formation of vitamin D in most land vertebrates, including humans.[3] The UV spectrum thus has effects both beneficial and harmful to life.

The lower wavelength limit of human vision is conventionally taken as 400 nm, so ultraviolet rays are invisible to humans, although some people can perceive light at slightly shorter wavelengths than this. Insects, birds, and some mammals can see near-UV

Sanitary compliance[edit]

A person wearing full protective gear, glowing in ultraviolet light

After a training exercise involving fake body fluids, a healthcare worker’s personal protective equipment is checked with ultraviolet light to find invisible drops of fluids. These fluids could contain deadly viruses or other contamination.

Ultraviolet light helps detect organic material deposits that remain on surfaces where periodic cleaning and sanitizing may have failed. It is used in the hotel industry, manufacturing, and other industries where levels of cleanliness or contamination are inspected.[83][84][85][86]

Perennial news features for many television news organizations involve an investigative reporter using a similar device to reveal unsanitary conditions in hotels, public toilets, hand rails, and such.[87][88]

 

Sterilization and disinfection[edit]

A low-pressure mercury vapor discharge tube floods the inside of a hood with shortwave UV light when not in use, sterilizing microbiological contaminants from irradiated surfaces.

Ultraviolet lamps are used to sterilize workspaces and tools used in biology laboratories and medical facilities. Commercially available low-pressure mercury-vapor lamps emit about 86% of their radiation at 254 nanometers (nm), with 265 nm being the peak germicidal effectiveness curve. UV at these germicidal wavelengths damage a microorganism’s DNA/RNA so that it cannot reproduce, making it harmless, (even though the organism may not be killed).[97] Since microorganisms can be shielded from ultraviolet rays in small cracks and other shaded areas, these lamps are used only as a supplement to other sterilization techniques.

UV-C LEDs are relatively new to the commercial market and are gaining in popularity.[failed verification][98] Due to their monochromatic nature (± 5 nm)[failed verification] these LEDs can target a specific wavelength needed for disinfection. This is especially important knowing that pathogens vary in their sensitivity to specific UV wavelengths. LEDs are mercury free, instant on/off, and have unlimited cycling throughout the day.[99]

Disinfection using UV radiation is commonly used in wastewater treatment applications and is finding an increased usage in municipal drinking water treatment. Many bottlers of spring water use UV disinfection equipment to sterilize their water. Solar water disinfection[100] has been researched for cheaply treating contaminated water using natural sunlight. The UV-A irradiation and increased water temperature kill organisms in the water.

Ultraviolet radiation is used in several food processes to kill unwanted microorganisms. UV can be used to pasteurize fruit juices by flowing the juice over a high-intensity ultraviolet source.[101] The effectiveness of such a process depends on the UV absorbance of the juice.

Pulsed light (PL) is a technique of killing microorganisms on surfaces using pulses of an intense broad spectrum, rich in UV-C between 200 and 280 nm. Pulsed light works with xenon flash lamps that can produce flashes several times per second. Disinfection robots use pulsed UV[102]

 

 

Folk Remedies for Improving your Life using only Hydro Jetting

YOUR LOCAL DRAIN CLEANER 

BAKER JETTING THOSE DRAIN LINES

As Spring arrives and the urge to clean arises, it the time to clean those drains. Your plumbing system is much like your arteries, they need to clear of obstructions to in order for proper flow and use. At Baker Plumbing, your local drainage contractor which means we clean drains locally, we have all the necessary equipment to do the job right the first time.

For commercial properties one of the most effective tools is the jetter. Capable of blasting dirt and debris with up to 3000 psi, those drains will sparkling inside and out. Most importantly your drains will remain trouble free with regular maintenance, ensuring no downtime during operating hours.

The next time your worried about your drains, give Baker Plumbing a call! We’re your local drain expert.

How does Drain Jetting work?

Drain jetting is a high pressure cleaning method for blocked drains and sewer pipes. It works by pumping water – which is stored in tanks – through a high pressure hose fitted with a jetting nozzle.

How does drain jetting work

This forces powerful streams of water into the pipe, allowing drainage engineers to target blockages and dislodge them with sustained assault.

 

Remove large drain blockages

Drain jetting is most useful when removing larger, stubborn blockages from pipes. Jetting hoses can negotiate tight bends in pipes, so are great for tackling clogs that would be difficult to reach by any other means – drain rods or DIY clearing kits, for instance.

 

Clean your drains in the process

Drain jetting is also an effective preventative measure. The sheer focused power of the jet spray won’t just remove a blockage, it will clean the pipe surface itself, reducing the risk of grime, oils, fats and other waste products gathering and turning back into a blockage.

As you can expect, this also improves the flow, efficiency and performance of your pipes; think of drain jetting as a highly intensive spa treatment for your sewer, refreshing it and restoring it back to peak performance.

CROSS CONNECTION CALGARY

In Calgary Backflow Testing is Mandatory!

BAKER AND BACKFLOWS, in action

Purpose

The following is presented to provide a general explanation on the subject of backflow prevention. It is not intended to be used in place of Code requirements and professionals should always utilize the code when making design, installation, and/or maintenance decisions. Definitions of italicized words follow at the end.

Overview

When drinking water piping connects to various plumbing fixtures or water utilizing equipment a cross-connection is created. If improperly protected, contamination can result when a backflow event occurs; allowing contaminates to reverse flow from the fixture/equipment back into the drinking water piping.

What Can Cause a Backflow

Conditions that are likely to create a backflow event are typically common, but unfavorable, hydraulic events that occur within the public or private segments of the water distribution system such as: an owner or worker draining down a house or building to make a plumbing repair; a broken water main or distribution pipe; severe/widespread power outages; fire fighters using large quantities of water to extinguish a fire, or; a water utilizing piece of equipment or process creating pressures greater than those present in water distribution system.

When these unfavorable hydraulic events are occurring, contaminates can be back-siphoned into the drinking water due to negative pressures; or contaminates can back-pressured into the drinking water due to excessive pressure imposed by the water utilizing piece of equipment or process.

Built-in Protection

Modern plumbing fixtures generally have built-in backflow protection. For instance, a faucet spout terminates above the flood rim level of the sink or tub. So if the sink or tub is full of dirty water or worse, backed-up sewage, there is no possible way for backflow because of the air gap created by the elevated spout. Toilet fill valves, clothes washers, dishwashers, and refrigerator/ice makers also employ some type of built-in air gap as their method of protection.

So around the home and office, for the most part, standard plumbing fixtures do not present a hazardous condition. However, additional protections are needed for household items such as: hand held shower heads; hose bibbs; lawn irrigation; and boilers.

Additional Protection Needed

In addition to the few items around the home that require additional protection, there are numerous applications within commercial and industrial processes that require additional protection. In general, these applications cannot utilize the air gap method of protection because the equipment or process requires a direct connection in order to utilize the dynamic pressure and flow that already exists within the water distribution system.

Therefore, directly connected water piping requires a different method of protection; the backflow preventer. A backflow preventeris a “one-way” appurtenance (an assembly of check valves or a vacuum breaker), that only allows water to flow in the desired direction and physically impedes reverse flow.

backflow testing

Types of Backflow Preventers

There are two basic types of backflow preventers: testable and non-testable.

Testable Backflow Preventers

also referred to as Backflow Prevention Assemblies; Backflow Assemblies; Testable Assemblies; or simply, Assemblies. Backflow Prevention Assemblies are generally required on the more hazardous cross connection applications, see below. By federal, state and local requirements as well as the manufacturer’s product listing, annual testing is required to ensure the assembly is good working order. This is due in part because the working components of a backflow assembly have a fairly short life expectancy and/or because sediment and debris can easily block their proper function.

When required testing fails to produce satisfactory results, assemblies must be cleaned and/or rebuilt as needed and retested. Un-repairable or obsolete assemblies must be replaced. See more below, for reporting, permitting, and licensing requirements.

Non-Testable Backflow Preventers

also referred to as Backflow Prevention Devices; Backflow Devices; Non-Testable Devices; or simply Devices. Backflow Prevention Devices are generally required on the less hazardous cross-connection applications, see below. Some devices are required to be replaced every five years; while others are good for the life of the fixture they serve or until they visibly fail (leak externally). See below.

Application of Backflow Preventers

the following is a quick view of applications that require either a testable or non-testable backflow preventer. For a comprehensive look at selection criteria please visit Table 5.1 in the WSSC Water Plumbing and Fuel Gas Code. In fact, take a look at Chapter 5 in its entirety; it is all about Cross-Connection Control.

Testable Applications:

Irrigation, in ground (All Homes & Businesses)
Commercial Boilers
Cooling Towers
Medical Equipment
Laboratory Uses
Commercial Water Treatment
Vehicle Washing Facilities
Commercial Fire Sprinklers
Processing Plants

Non-Testable Applications:

Residential Hose Bibbs
Hand Held Shower Heads
Emergency Eye Wash
Residential Fire Sprinkler
Residential Boilers
Commercial Ice Makers
Beverage Dispensers
Residential Humidifiers
Food Service Equipment

Non-Testable Devices; 5 Year Replacement – the following devices require replacement every five years:

ASSE 1012 – Dual Check Valve; with Atmospheric Vent
ASSE 1022 – Dual Check Valve; with Atmospheric Vent for Carbonated Beverage Dispenser
ASSE 1024 – Dual Check Valve

These devices require tagging to identify the installation and/or expiration date. Homeowners can replace these devices without permit or inspection.

Cross-Connection Technicians

also referred to as Backflow Technician; Backflow Tester; or simply, Tester. By Maryland Law, and subsequently by WSSC Water Plumbing Code, Backflow Techs must be registered as, at minimum, a Journeyman Plumber and also have completed a WSSC Water Approved 32-hour certification course for Cross-Connection Technicians (and recertify every 3 years).

LISTED BELOW IS JUST SOME OF THE COMPLEX SYSTEMS THAT MAKE UP YOUR DRAINAGE. DON’T RISK DAMAGE AND GREATER EXPENSE!! CALL A PROFESSIONAL PLUMBER TODAY!!

DWV systems maintain neutral air pressure in the drains, allowing free flow of water and sewage down drains and through waste pipes by gravity. It is critical that a sufficient downward slope be maintained throughout, to keep liquids and entrained solids flowing freely towards the main drain from the building. In some situations, a downward slope out of a building to the sewer cannot be created, and a special collection pit and grinding lift “sewage ejector” pump are needed. By contrast, potable water supply systems operate under pressure to distribute water up through buildings, and do not require a continuous downward slope in their piping.

Every fixture is required to have an internal or external trap; double trapping is prohibited by plumbing codes due to its susceptibility to clogging. Every plumbing fixture must also have an attached vent. The top of stacks must be vented too, via a stack vent, which is sometimes called a stink pipe.[1]

All plumbing waste fixtures use traps to prevent sewer gases from leaking into the house. Through traps, all fixtures are connected to waste lines, which in turn take the waste to a “soil stack”, or “soil vent pipe”. At the building drain system’s lowest point, the drain-waste vent is attached, and rises (usually inside a wall) to and out of the roof. Waste exits from the building through the building’s main drain and flows through a sewage line, which leads to a septic system or a public sewerCesspits are generally prohibited in developed areas.

The venting system, or plumbing vents, consists of a number of pipes leading from waste pipes to the outdoors, usually through the roof. Vents provide a means to release sewer gases outside instead of inside the house. Vents also admit oxygen to the waste system to allow aerobic sewage digestion, and to discourage noxious anaerobic decomposition.[further explanation needed] Vents provide a way to equalize the pressure on both sides of a trap, thereby allowing the trap to hold the water which is needed to maintain effectiveness of the trap, and avoiding “trap suckout” which otherwise might occur.

sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere. When a column of waste water flows through a pipe, it compresses air ahead of it in the pipe, creating a positive pressure that must be released so it does not push back on the waste stream and downstream trap water seals. As the column of water passes, air must freely flow in behind the waste stream, or negative pressure results. The extent of these pressure fluctuations is determined by the fluid volume of the waste discharge.

Excessive negative air pressure, behind a “slug” of water that is draining, can siphon water from traps at plumbing fixtures. Generally, a toilet outlet has the shortest trap seal, making it most vulnerable to being emptied by induced siphonage. An empty trap can allow noxious sewer gases to enter a building.

On the other hand, if the air pressure within the drain becomes suddenly higher than ambient, this positive transient could cause waste water to be pushed into the fixture, breaking the trap seal, with serious hygiene and health consequences if too forceful. Tall buildings of three or more stories are particularly susceptible to this problem. Vent stacks are installed in parallel to waste stacks to allow proper venting in tall buildings.

Most residential building drainage systems in North America are vented directly through the building roofs. The DWV pipe is typically ABS or PVC DWV-rated plastic pipe equipped with a flashing at the roof penetration to prevent rainwater from entering the buildings. Older homes may use copperironlead or clay pipes, in rough order of increasing antiquity.

Under many older building codes, a vent stack (a pipe leading to the main roof vent) is required to be within a 5-foot (1.5 m) radius of the draining fixture it serves (sink, toilet, shower stall, etc.). To allow only one vent stack, and thus one roof penetration as permitted by local building code, sub-vents may be tied together inside the building and exit via a common vent stack. One additional requirement for a vent stack connection occurs when there are very long horizontal drain runs with very little slope to the run. Adding a vent connection within the run will aid flow, and when used with a cleanout allows for better serviceability of the long run.

A blocked vent is a relatively common problem caused by anything from leaves, to dead animals, to ice dams in very cold weather, or a horizontal section of the venting system, sloped the wrong way and filled with water from rain or condensation. Symptoms range from bubbles in the toilet bowl[citation needed] when it is flushed, to slow drainage,[citation needed] and all the way to siphoned (empty) traps which allow sewer gases to enter the building.

When a fixture trap is venting properly, a “sucking” sound can often be heard as the fixture vigorously empties out during normal operation. This phenomenon is harmless, and is different from “trap suckout” induced by pressure variations caused by wastewater movement elsewhere in the system, which is not supposed to allow interactions from one fixture to another. Toilets are a special case, since they are usually designed to self-siphon to ensure complete evacuation of their contents; they are then automatically refilled by a special valve mechanism.[citation needed]

Mechanical vents (also called cheater vents[2]) come in two types: Air admittance valves and check vents, the latter being a vent with a check valve.

Air admittance valves (AAVs, or commonly referred to in the UK as Durgo valves and in the US as Studor vents and Sure-Vent®) are negative-pressure-activated, one-way mechanical valves, used in a plumbing or drainage venting system to eliminate the need for conventional pipe venting and roof penetrations. A discharge of wastewater causes the AAV to open, releasing the vacuum and allowing air to enter the plumbing vent pipe for proper pressure equalization.

Since AAVs will only operate under negative pressure situations, they are not suitable for all venting applications, such as venting a sump, where positive pressures are created when the sump fills. Also, where positive drainage pressures are found in larger buildings or multi-story buildings, an air admittance valve could be used in conjunction with a positive pressure reduction device such as the PAPA positive air pressure attenuator to provide a complete venting solution for more complicated drainage venting systems.

Using AAVs can significantly reduce the amount of venting materials needed in a plumbing system, increase plumbing labor efficiency, allow greater flexibility in the layout of plumbing fixtures, and reduce long-term roof maintenance problems associated with conventional vent stack roofing penetrations.

While some state and local building departments prohibit AAVs, the International Residential and International Plumbing Codes allow it to be used in place of a vent through the roof. AAVs are certified to reliably open and close a minimum of 500,000 times, (approximately 30 years of use) with no release of sewer gas; some manufacturers claim their units are tested for up to 1.5 million cycles, or at least 80 years of use. AAVs have been effectively used in Europe for more than two decades.[when?]

Island fixture vent for under-cabinet waste plumbing

An island fixture vent, sometimes colloquially called a “Chicago Loop”, “Boston loop” or “Bow Vent”, is an alternate way of venting the trap installed on an under counter island sink or other similar applications where a conventional vertical vent stack or air admittance valve is not feasible or allowed.

As with all drains, ventilation must be provided to allow the flowing waste water to displace the sewer gas in the drain, and then to allow air (or some other fluid) to fill the vacuum which would otherwise form as the water flows down the pipe.

An island fixture vent provides an elegant solution for this necessity: when the drain is opened, water displaces the sewer gas up to the sanitary tee, the water flows downward while sewer gas is displaced upward and toward the vent. The vent can also provide air to fill any vacuum created.

The key to a functional island fixture vent is that the top elbow must be at least as high as the “flood level” (the peak possible drain water level in the sink). This ensures that the vent never becomes waterlogged.

The cost of installation is high because of the number of elbows and small pieces of pipe required. The largest cost outlay with modern plastic drain pipes is labor. Use of street elbows is helpful.

Alternately if moving sink to an island sink, install the P-trap below the floor of the island and vent off the top of the drain. Attach toward the trap and reverse 180 degrees so any water in the vent flows down the drain. Slope drain down, slope vent up, and attach to existing vent from previous existing fixture that is now abandoned. Patch previously existing drain to become vent. In Canada, the national plumbing code requires that the minimum trap arm be at least 2 times the pipe diameter, (e.g., 1.25 inch pipe needs a 2.5-inch trap arm, 1.5 pipe needs a 3-inch trap arm, etc.) and that the vent pipe be one size larger than the drain that it serves, also a cleanout is required on both the vent and the drain. The reason for this is in the event of a plugged sink, the waste water will back up and go down the vent, possibly plugging the vent (as it is under the countertop), and a clean-out would permit the cleaning of the pipes.

Homer Simpson’s Guide to Grooving Copper Pipe

Even better the young apprentices that have their fingers on the button as it were and ready to show the world how this important skill can be developed. With a whole 5 years of experience between them, what could possibly go wrong? Follow along as the steps needed to complete this important skill are discussed. If you’re looking for a commercial plumber near you then look no further than Baker Plumbing in Calgary.

Copper Pipe

Copper pipes are commonly used in the commercial construction industry for water supply lines and refrigerant lines in HVAC (heating, cooling, and air-conditioning) systems. Copper pipes can be manufactured as soft or rigid copper and offer excellent corrosion-resistance and reliable connections. The three most common types of copper pipe used in residential and commercial construction are Type K, Type L, and Type M. A fourth type, used for drain-waste-vent, or DWV, piping, can be found in some older homes.

For today we using 2.5″ copper K pipe which is the only type or quality that is approved for this type of joining method. Working on commercial boiler systems can be a hazardous undertaking. This work should only be completed by professional tradesmen or women that have extensive experience completing such work. Or as shown here under the direct supervision of a Master plumber.

  • Type K Copper Pipe: Type K copper pipe has the thickest wall of all the common types. It is used for water distribution, fire protection, oil, HVAC, and many other applications in the construction industry. Type K pipe is available in a rigid and flexible form and can be used with flared and compression fittings. Pictured below is that very thing, Type K copper pipe! It’s been cut, reamed and sanded in preparation for the application of a RIDGID grooving tool.

Next step grooving

According to many industry experts “grooved mechanical piping” reduces risk, cost and construction schedules.

Grooved mechanical pipe joining is a method of fabricating piping systems that eliminates the need for welding and flanging pipe. Grooved-end pipe, fittings, valves and accessories are joined with mechanical couplings that provide a secure, reliable union at every joint. These connections are designed to handle a variety of utility and process piping services. Grooved pipe solutions can be used on carbon steel, stainless steel and galvanized pipe, as well as high-density polyethylene (HDPE), fiberglass-reinforced pipe and American Water Works Association ductile iron pipe ranging in size from a half inch to 60 inches.

A grooved pipe joint is comprised of three core elements: the pipe groove; the gasket and coupling housings; and nuts and bolts. Grooves are cold-formed on the pipe ends with tooling specifically designed for this process (we are using the RIDGID 914). The coupling housing engages the grooved ends of each pipe, fitting or valve to be connected. A resilient, pressure-responsive elastomeric gasket provides a leak-tight seal, even under a vacuum. The coupling housing fully encloses the gasket, reinforcing the seal and securing its position. The coupling is fastened with two track head bolts and nuts.

Grooved mechanical piping has its roots in World War I, during which this innovation was used to deploy fuel and water to Allied forces on the front lines. The system proved beneficial over other joining methods, because as troops’ positions changed, the pipes needed to be disassembled, transported and reassembled quickly and efficiently.

Today, the grooved pipe system still proves advantageous in critical fluid handling applications. Grooved piping systems can be installed on a variety of piping applications, including alcohol; caustic; chilled, cooling, potable, wash and demineralized water; fire protection; glycerin; instrument and plant utility air; oil feed; reverse osmosis; and wastewater treatment.

Pictured below is Peter with Baker Plumbing using the RIDGID 914, a product no longer made by RIDGID but continues to be useful and effective in completing complex plumbing and heating work.

The tools that actually make it work

The RIDGID® 915 Roll Groover is a manual roll groover for in-place field applications. The 915 requires only 3 1/2″ of clearance to travel around a pipe and a minimum of 2 3/4″ of exposed pipe for grooving. With the appropriate roll sets, the 915 can groove from 1 1/4″ to 12″ pipe, the widest range in its class! The 915’s cast-in handle allows for easy transport or chaining the groover down to prevent theft. The 915 is a must for service work crews. RIDGID TOOLS

Baker Boys in Action

Here at Baker plumbing we want to provide the best tech while using the best tech!

The choice of who works on your furnace, the heart of your HVAC system and the very appliance keeping Old Man Winter at bay, should be made carefully. There is alot of smoke and mirrors out there and you can trust Baker to clear the air!

Types of Furnaces 

While worldwide there are many different types of furnaces, in Alberta there are generally only 2 based on fuel source.

  • Natural gas
  • Propane

Once past the fuel the field becomes much more cluttered with such verbiage as first and second stages, PSC or ECM motors, exchanger metal types and on and on.

The government legislation mandating the efficiency ratings, the minimum allowable is 92% has left manufacturers and sellers to add new components at a furious rate to gain a percent here and one there!

Baker recommendations

While new technology is impressive and even amazing, our belief is still to keep things as simple as possible. We recommend the following

  • the basic 92% efficiency model
  • single stage gas valve
  • PSC motor
  • stainless steel exchanger

Those components will give you the 92% efficiency rating, low operating costs and the least potential for an expense repair bill in the future.

Still confused or have questions?

At Baker we can answer and solve any of your questions or problems.
