Calgary has one of Alberta’s most comprehensive cross-connection control programs, and for good reason. With so many properties connected to irrigation systems, fire suppression lines, and commercial-grade boilers, the risk of contaminants entering the municipal water supply is higher in an urban setting. This is why the City of Calgary requires certified annual testing of all backflow prevention assemblies.
Our licensed Calgary plumbers not only test and certify your device, but also take the time to explain results and recommend cost-effective solutions if repairs are needed. Whether you’ve received a 30-day reminder notice from the City, or you want peace of mind that your water is safe, we provide full-service cross connection control, including:
Protecting Calgary’s water supply is a shared responsibility—and we make it simple for homeowners, property managers, and businesses to stay in compliance without hassle.
A typical backflow test in Calgary takes less than 30 minutes to complete:
Once complete, we electronically submit your test report to the City of Calgary and email you a copy for your records. You don’t have to handle any paperwork.

In a large urban setting like Calgary, cross connections are common—irrigation systems, fire suppression lines, boilers, and even pools or hot tubs can all create a risk of contaminants entering the municipal water supply. That’s why the City requires annual backflow prevention testing in Calgary for all cross connection control devices.
If a device isn’t working properly, substances such as fertilizers, pesticides, human waste, pool chemicals, and detergents could potentially seep into the drinking water. Our job is to make sure that never happens with our certified backflow testing services.
Don’t put the health of you or your family at risk. Whether you need residential or commercial backflow device testing in Calgary, our certified cross connection specialists ensure your water is safe for drinking, washing, and bathing.

Backflow problems aren’t always obvious, but there are a few warning signs that can indicate your plumbing system isn’t working properly. If you notice any of the following, it may be time to schedule a certified backflow test:
Backflow can pose serious health risks, which is why annual testing by a certified Calgary backflow tester is required by law. Early detection and maintenance not only protect your household or business but also help keep the city’s drinking water safe for everyone.
Backflow prevention systems are most commonly required in commercial buildings, but certain residential properties must also have them in place—especially when cross-connections exist between the home’s plumbing system and the municipal water supply.
In Calgary, residential properties that feature any of the following systems typically require a backflow prevention assembly:
These types of water systems can create cross-connections that may allow contaminants such as chemicals, chlorine, pesticides, detergents, or even human waste to enter the community’s potable water supply. Installing the proper backflow prevention device ensures compliance with City of Calgary regulations and keeps drinking water safe.
Common code-compliant devices include:
Property owners in Calgary who already have a backflow device will typically receive a notice from the City about 30 days before annual testing is due. Scheduling timely testing and maintenance ensures continued compliance with local regulations and helps safeguard both your property and the municipal water system.
We will perform a thorough inspection of your backflow prevention system, including checking for valve leaks. If there are any issues with your backflow device, we will alert you to the problem and carry out the necessary repairs and/or replacements.
After completing the test, we will fill out a report and submit it to the city. The entire testing process typically takes thirty minutes to complete if there are no pre-existing issues with your system.
A cross connection is any connection between pipes that carries water, potable or non-drinking water. So, wherever a cross connection exists a backflow device is required. When functioning properly, a backflow device prevents unsavory odors, tastes, or harmful contaminants from mixing with drinking water. Typical cross connections include: radiant heating systems, boilers, hot tubs, sprinklers, swimming pools, soda fountain machines, irrigation systems, and suppression systems.
We offer flat-rate pricing for certified backflow testing in Calgary, Airdrie and surrounding areas.
Our rates:
• $99.00 for the first device per site

Cross connection control devices are required by law to be tested annually, and a report needs to be filed with the City of Calgary afterwards. Most Backflow assemblies include a check valve (or valves), a set of springs, and once in a while, a relief valve comes with it. Each of these parts must be inspected and tested annually to ensure that they are properly maintained. To pass inspection, check valves must be able to hold a minimum amount of pressure.

Backflow occurs in two ways:
