Backflow Testing & Repair in Calgary
Do You Need a Backflow Test in Calgary?
The City of Calgary requires annual backflow testing to keep municipal drinking water safe. Homeowners typically schedule testing after receiving an official notice, installing a lawn sprinkler system, or selling a home.
A backflow preventer stops contaminated water from flowing backward into your clean drinking water supply. This protects your water from lawn fertilizers, irrigation chemicals, and stagnant water.
Your certified technician from Cedar Mechanical inspects the assembly, checks pressure differentials, and completes the official report. When your device passes, you receive your completed paperwork immediately. If repairs are needed, you get a fixed quote before work starts.

Frequently Asked Questions
How much does a backflow test cost in Calgary?
How often do I need to test my backflow preventer?
Most backflow assemblies require annual testing, especially systems connected to irrigation. Check your City notice for your exact renewal date.
Do you submit the completed test report to the City for me?
We submit the report for you, and you receive a copy for your records. Your technician completes the official test report on site the moment your device passes, and hands you a copy that’s ready to file with the City.
What happens if my backflow device fails the test?
If a valve leaks or fails pressure checks, your technician points out the problem and provides a fixed quote for repairs or replacement before doing any work.
Do I need a backflow test for my lawn sprinkler system?
Yes. Irrigation systems present a cross-connection risk because fertilizers and lawn water can siphon into household drinking water.

Yes. Every technician is provincially certified. Cedar Mechanical is licensed in Alberta, covered by a $100,000 service blanket bond, and provides a 2-year warranty on repairs.
