Cross Connection Control Device Testing & Repairs
Did you know that municipalities across Alberta are legally responsible for protecting their drinking water?
The cross control test is an ANNUAL test, performed by a certified AWWA tester that confirms that all devices designed to protect our drinking water, are functioning correctly.
We are trained and certified by the American Water Works Association – Western Canada Section.
Irrigation Systems in Calgary
City of Calgary Bylaw 39.3e requires all testable cross-connection devices on an irrigation system, be tested on STARTUP each spring.
On residential buildings, we see them typically on in-floor heating/boiler systems and on lawn irrigation/underground sprinkler systems.
Each commercial building has at least one device, but most have multiple devices that include car washes, in-floor heating systems, fire protection systems, irrigation, etc.
All irrigation systems installed in a residential home after 2005, must have a testable device.

Besides getting frequently annoying letters from the City, the City of Calgary, or the local municipal water purifier can and will fine you.
In Calgary, the City of Calgary Bylaw: 40M2006 39(3) – Failure to Test can and does result in $1500 fines. On top of that, they will lock out the device and/or have the water shut off to the building, for failing the test.
The goal of the cross connection program is to make sure that the water is safe to drink for everyone.
A cross-connection is a temporary or permanent link between a potable (drinking) water system and any source containing non-potable water or other substances from which backflow may occur.
Examples include the piping between a public water system, or a citizen’s water system and a heating or cooling system, fire suppression system or irrigation system.
What is a cross-connection control device?
A cross-connection control device is a mechanical device that prohibits backflow of water into the public drinking water.
The main testable types of cross-connection control devices are the reduced-pressure principle assembly (RP), the pressure vacuum breaker assembly, the double-check valve (DCV) assembly and registered Air Gaps.
Examples of secondary types of devices are the hose connection vacuum breakers, atmospheric vacuum breakers and residential dual check valves.

Cross-connection control devices have internal seals, springs and moving parts that are subject to fouling, wear or fatigue; therefore, all cross-connection control devices have to be tested to ensure they are functioning properly.
Did you know?
At the “World Fair” in Chicago, IL in 1933, records show that 98 people died while 1409 other were very sick. The cause was found to be a lack of back siphonage on the plumbing systems. The need for cross-connection control became much more apparent after this event.
