How often do backflow preventer valves need to be replaced?

Replace a backflow preventer when it fails testing, leaks from relief ports, won’t hold pressure, or can’t be rebuilt. The timeline varies by water quality, system pressure, outdoor exposure, and usage. Many assemblies can be serviced with internal rebuild kits; a technician will confirm if repair or full replacement is best after inspection. In Roanoke and nearby areas, we recommend routine professional checks to prevent contamination and downtime.

Quick checks:

  • Look for dripping from the relief port.
  • Check for corrosion or mineral buildup.
  • Note unexplained pressure drops.
