Backflow Prevention Testing in Orillia, Barrie & North Bay — Certified. Compliant. On Record.

If you’ve received a letter from the city or your insurance provider asking for backflow device testing — you’re in the right place.

Poly-B Plumbing provides licensed backflow prevention testing for commercial, multi-unit, and residential properties across Orillia, North Bay, and surrounding areas. We’re certified to test, document, and file reports with your local municipality — so you stay compliant and protected.

What is Backflow Testing?

Backflow happens when water flows in the wrong direction — potentially contaminating the public water supply. That’s why certain properties are required by law to install and test a backflow preventer annually.

A backflow prevention test confirms that your device is working correctly and meets municipal standards. If it fails, we provide fast repair or replacement options — and re-test once corrected.
