Backflow Prevention & Testing in Burlington
A backflow preventer stops contaminated water — from irrigation systems, boilers, and commercial equipment — from flowing back into the municipal drinking water supply. Halton Region requires it to be tested every year. At Mountain Grove Plumbing, our licensed plumbers install, test, and repair backflow devices for homes and businesses in Burlington, Oakville, and Hamilton, and we file the report with Halton Region for you.
Annual Testing
Yearly testing of your backflow prevention device, with the test report filed with Halton Region and a copy for your records.
Installation
Correct device sizing and code-compliant installation for commercial, multi-residential, and irrigation connections.
Repair & Replacement
Failed the test? We repair or replace the device, re-test it, and get your property back into compliance without delay.
Testing Reminders
We remind you before your annual test is due, so your property never falls out of compliance with Halton Region.
Who Needs Backflow Testing?
Most commercial buildings, multi-residential properties, and any home with an in-ground irrigation system connected to municipal water need annual backflow testing. If Halton Region sent you a notice, your test is due — and non-compliant properties can face issues with their water service. Book the test and stay compliant.
