What is a boiler?

A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications,[1][2] including water heating, central heating, boiler-based power generation, cooking, and sanitation.

Is a boiler safe?

To define and secure boilers safely, some professional specialized organizations such as the American Society of Mechanical Engineers (ASME) develop standards and regulation codes. For instance, the ASME Boiler and Pressure Vessel Code is a standard providing a wide range of rules and directives to ensure compliance of the boilers and other pressure vessels with safety, security and design standards.[8]

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).

BACKFLOW AND CROSS CONNECTION TESTING

BAKER IN ACTION

Cross connection or backflow testing is a critical part of a building’s infrastructure. With annual testing of these devices a requirement for all commercial properties, coupled with the need for certified testers and equipment, their importance cannot be overstated.In Calgary, some homes and businesses have cross connection devices at their properties. This device prevents water that has been used for washing, heating and cooling from flowing into our drinking water. The City of Calgary oversees annual testing and compliance of these devices in order to protect Calgary’s drinking water supply from contamination.

I have a cross connection testing letter, Now what???

If you received a letter, you need to have your cross connection device tested by a certified tester who is registered with the City of Calgary.

After testing is completed, the tester should submit the report to our office in 30 days. Check with your tester to make sure the report was filed with us and that you have received a copy of the test report.

To learn more about cross connection devices, home owner and business responsibilities, and certifications and renewals for cross connection testers, please visit the resources below:
