How often does a backflow preventer need to be inspected?

Inspection frequency depends on local code requirements and the type of backflow preventer installed. A licensed plumber should confirm the required testing schedule for your specific address. We serve homes and businesses across Appleton, Kaukauna, Menasha, and nearby areas.

Quick checks:

  • Read the test tag on the device to find the last test date.
  • Watch for leaks, a dripping relief port, or reduced water pressure.
  • If you receive a city notice, schedule testing before the due date.
