How often do backflow preventer valves need to be replaced?
Backflow preventer valves are replaced when they fail a professional test, leak, or can’t be reliably repaired. There isn’t a fixed timeline, because water quality, usage, and installation conditions vary by home and business. Our licensed plumbers can test your device, service it if possible, and recommend replacement only when it’s the safest choice in Ashburn and nearby areas.
Quick checks:
- Failed test or won’t hold pressure
- Persistent leaking or dripping
- Corrosion, cracks, or damaged parts
- Stuck or inconsistent shutoff
