The testing of your Calgary cross connection control device must be performed annually by a certified Calgary backflow tester to comply with local regulations. Our experienced team conducts thorough backflow tests, performs necessary repairs, and certifies newly repaired or installed backflow prevention valves.

The backflow test requires temporarily shutting off the water, takes less than 30 minutes to complete, and involves opening and closing the check valves to identify any irregularities in the system.

If an issue is detected with your backflow device, we’ll provide you with a detailed report of the test results and discuss the necessary repairs to ensure your drinking water remains protected. Our team takes the time to fully explain the problem and the steps required to restore your system to full compliance.

Our licensed Calgary plumbers handle all necessary repairs to correct any issues, ensuring your system meets all Calgary regulatory requirements. We install, test, and maintain backflow prevention devices on both commercial and residential water supply lines across Calgary to prevent cross-contamination and protect your drinking water.

We perform backflow testing to ensure:

• The check valves are functioning correctly to prevent backflow
• The relief valves open and close as needed
• The air ports in the backflow device open properly

To save you time, we handle all paperwork and will submit the necessary forms after completing the test. You’ll receive a copy of the report via email, so you don’t have to worry about it!

Backflow prevention systems are most often installed in commercial buildings; however, some residential properties are also required to have these systems in place—particularly if your home features cross-connections between your plumbing system and the municipal water line. Calgary residential properties featuring the following systems will be required to install backflow prevention assemblies:

• Irrigation Systems (lawn sprinklers)
• Fire Suppression Systems
• Pools or Ponds
• Commercial-Grade Boilers (typically found in multi-family buildings)

These water systems mentioned above can potentially result in cross-connections and introduce contaminants such as chemicals, chlorine, pesticides, and even human waste into the community’s potable water supply. KaiTech Plumbing & Heating is here to help you install the right type of backflow prevention device to help your property remain in compliance with the City of Calgary regulations. We can provide you with code compliant backflow devices, including:

• Double check assemblies
• Double check detector assemblies (fire suppression)
• Lead-free reduced pressure principle backflow assembly (residential water lines)

If you currently have a backflow device in Calgary, you can expect a notice from the City of Calgary reminding you to schedule backflow testing; this is often mailed to you 30 days before the deadline. To ensure your home or business continues to comply with local regulations—contact us today at (403) 945-8324 to schedule service with our certified Calgary Cross Connection and Backflow Specialist.

Backflow is a serious concern for both residential and commercial properties, as it occurs when clean, potable drinking water becomes contaminated with wastewater. This happens when there is a reversal of water flow in your plumbing system, allowing potentially harmful substances to enter the clean water supply. 

To prevent this from happening, backflow prevention devices are used to ensure that water flows only in the intended direction — away from the drinking water supply.

In Calgary, cross connection control devices are critical in safeguarding your water supply. They are designed to prevent backflow caused by either back pressure or back siphonage. Understanding the difference between these two types of backflow is key to maintaining a safe water supply and ensuring compliance with local regulations. Here’s a breakdown of both types of backflow:

Back Pressure Backflow:

Back pressure backflow occurs when the pressure in a downstream system becomes higher than the pressure in the main water supply. This can happen in situations like pumping water from a tank into your plumbing system or in industrial settings where equipment creates higher pressure than the water supply. When this happens, water can flow backward into the public water system, potentially carrying contaminants along with it.

Common causes of back pressure backflow:

• Booster pumps in industrial or commercial facilities
• Pressurized irrigation systems
• Heating systems using water as a medium

Back Siphonage Backflow:

Back siphonage occurs when there is a sudden drop in water pressure in the supply line, often due to events like water main breaks, high demand periods (such as firefighting efforts), or sudden shutdowns of the water system. This creates a vacuum effect that can draw contaminated water back into the clean water supply. For instance, if a hose is left in a pool or a sink with wastewater, back siphonage could cause water to flow backward into the supply pipes, potentially contaminating the clean water.

Common causes of back siphonage backflow:

• Sudden pressure drops in the water supply
• Unprotected hose bibs or irrigation systems
• Any situation where there is an interruption in the water supply that creates a vacuum

How Backflow Prevention Devices Protect Your Water Supply

To ensure the safety of your drinking water, backflow prevention devices are essential. These devices, such as check valves, air gaps, and backflow preventers, are installed on your water lines to allow water to flow in only one direction. Whether you're in a residential area or managing a commercial property, it's crucial to have the correct backflow protection in place to prevent any reverse flow of water that could compromise water quality.

In Calgary, it’s required by law to have your backflow prevention system tested annually by a certified backflow tester to ensure it’s working as intended. If you're unsure about whether your system is properly maintained or need to schedule a test, reach out to our certified backflow testers today.
