How often do backflow preventer valves need to be replaced?

There is no fixed replacement interval for backflow preventers. Replacement happens when the device is damaged, corroded, leaking, or cannot pass a performance check during a maintenance visit. We install backflow devices and offer plumbing maintenance & inspections, so a technician can assess condition and advise repair vs. replacement for your home in Oakland or San Ramon.

Quick checks:

• Visible leaks or corrosion
• Continuous discharge from the relief port
• Reduced water pressure after the valve
