Portland’s Backflow Preventer Maintenance Experts
Ensure your drinking water stays safe and your plumbing stays code-compliant. We offer certified backflow inspections, maintenance, and testing across Portland.
What Is Backflow Preventer Maintenance?
Backflow preventers stop contaminated water from flowing backward into your clean water supply. Regular maintenance is not just recommended—it’s often required by Portland city code for homes with irrigation systems, fire sprinklers, or other at-risk setups.
Our team tests, services, and maintains your backflow devices to ensure they work properly and meet all regulations.
