Certified Backflow Testing in Surrey & Metro Vancouver
Protecting your drinking water. Ensuring municipal compliance.
A backflow preventer is one of the most important components of your irrigation system. Its job is simple but vital: it prevents contaminated water—containing fertilizers, pesticides, or animal waste—from flowing backward into your clean drinking water supply.
Because of this high stakes safety role, most municipalities across Metro Vancouver (including Surrey, Delta, Langley, and White Rock) require that these devices be tested and certified annually by a licensed professional.

The Hazards of “Backflow”
Backflow usually occurs during a “pressure drop” in the city water main (like when a fire hydrant is opened or a water main breaks). This creates a vacuum effect that can suck stagnant irrigation water into your home’s faucets.
Common Causes of Failure:
Worn Rubber Seals: Over time, the internal gaskets become brittle or debris gets trapped in the checks.
Winter Damage: If not properly winterized, the internal brass components or plastic modules can crack.
Scale Buildup: Mineral deposits from the water can prevent the device from closing tightly.
Frequently Asked Questions: Backflow Testing
How often do I need a backflow test in Surrey?

What happens if my backflow preventer fails the test?
Don’t worry—most “fails” are caused by simple debris or worn-out rubber parts. Our technicians can usually clean or rebuild the internal components during the same visit to ensure you pass and stay compliant.
Can I test it myself?
No. Backflow testing must be performed by a certified Backflow Assembly Tester using specialized, calibrated equipment to ensure accuracy and meet municipal legal requirements.
