Backflow compliance, handled end to end

Backflow preventers protect the drinking-water network from cross-connections. In most Greater Montreal municipalities, owners of commercial, industrial and institutional buildings must have their testable devices verified periodically — typically annually — by a recognized tester.

In practice, that means tracking deadlines, booking a tester, keeping reports and filing paperwork with the city. That’s exactly what we take off your desk.

What’s included

One vendor from test to repair

Many testers only test. If the device fails, you’re left finding a plumber and booking a retest. As a division of an RBQ-licensed general contractor, we close the loop: test, repair, replace and recertify — one team, one invoice.

Frequently asked questions

How often must a backflow preventer be tested?

As a general rule, testable backflow preventers must be verified at least once a year, and after any repair or relocation. Exact requirements vary by municipality and device type — we confirm what applies to your building and handle the reminders.

What happens if my device fails the test?

A failed device must be repaired or replaced, then retested. Because we are also plumbing contractors, we handle the repair and the new test in one engagement — no second vendor needed.

Who receives the test report?

You get a copy, and we file it with the required parties (municipality or building manager as applicable). You keep a complete written trail for insurance and audits.
