How often do backflow preventer valves need to be replaced?
Most backflow preventer valves are replaced when they fail a certified test, leak, or show corrosion—not on a fixed schedule. Lifespan varies by water quality, installation, and exposure to freezing. We recommend periodic testing; a technician will confirm if repair or full replacement is the safest option for your home in Garden City, NY.
Quick checks:
- Failed test or can’t hold pressure
- Continuous dripping or visible rust
- Stuck, noisy, or frozen components
- Past flood or freeze event
