How often do backflow preventer valves need to be replaced?
There isn’t a fixed replacement timeline for backflow preventer valves. Replace them when they fail required testing or show damage. Signs include leaks, corrosion, or parts that won’t seal or hold pressure. In Roanoke and nearby areas, a technician can test, service, or replace the assembly after inspection.
Quick checks:
- Dripping from relief port or vent
- Visible corrosion or cracks
- Low or fluctuating water pressure
- Valve sticks, chatters, or won’t close
