How often do backflow preventer valves need to be replaced?

Backflow preventer valves are replaced when they fail a professional test or show damage, not on a fixed schedule. Lifespan depends on water quality, usage, and weather exposure. Many issues can be fixed with internal repair kits before full replacement. Replace if it repeatedly fails testing, leaks at the relief port, has a cracked body, or severe corrosion. We can inspect, test, and confirm costs on site in St. Louis and nearby.

Quick checks:

• Visible leaks or rust.
• Drips from relief valve.
• Stiff or broken shutoff handles.
