Looking for professional backflow testing in Coquitlam? Griffin Backflow offers certified inspections, compliance reporting, and ongoing maintenance services tailored to residential, commercial, and industrial properties. With more than 20 years of experience, we understand Coquitlam’s bylaws, building codes, and safety regulations—so you stay compliant without the stress.
Whether it’s your annual test or a new installation, our team is ready to help keep your water safe, your systems up to code, and your documentation fully handled.
Why Backflow Testing in Coquitlam Is Essential
Backflow happens when water flows in reverse due to changes in pressure. This reversal can draw contaminated water—like chemicals, bacteria, or other pollutants—into your drinking supply. That’s why the City of Coquitlam requires backflow prevention assemblies to be tested annually in many buildings, especially those with irrigation systems, fire sprinklers, or complex plumbing.
We handle everything from inspection to submission of results to the city. Whether you manage a multi-unit building or own a single property, we ensure your system meets Coquitlam’s current standards.

Backflow Preventer Maintenance in Coquitlam
Annual testing is important—but proactive maintenance keeps your system reliable long-term. Over time, parts wear down and systems can fail without warning. Our Coquitlam backflow maintenance services are designed to prevent those failures before they happen.
