Backflow Prevention and Testing

Certified backflow testing for commercial, industrial, and agricultural sites across the Fraser Valley.

Every building in the Lower Mainland is required by law to protect its water supply from contamination. That protection is called premise isolation, and the device that does it is a backflow preventer. Commercial, industrial, and agricultural sites need testable assemblies, and many also need component isolation on individual systems.

Alpine technicians are certified to test, repair, and install backflow assemblies. If you add chemicals, fertilizer, or medication anywhere near your water lines, whether that is a poultry barn, a golf course, an irrigation system, or a process line, a working backflow preventer is what keeps that out of the drinking water.

What we handle

Testing, repair, and installation done right.

Why it matters

A device that passed last year can fail this year.

Backflow assemblies fail quietly. A device that passed last year can fail this year, and you will not know until it is tested. Staying on top of annual testing keeps you compliant and keeps your water safe.

Chilliwack, BC · Since 1969

The mountain on our wall.
The standard in our work.

Freshly painted across our Chilliwack shop, the mural is a new Fraser Valley landmark, and a fitting one. Local artist Jack Hensby brought the mountain to life, and it will feature in the Chilliwack Mural Festival. The peak has been our namesake since 1969, and it is the standard we bring to every install, service call, and 2 AM emergency. We back the local community the way it has backed us.
