Backflow is the reversal of water flow in a pipeline, which can be both dangerous and costly. Backflow assemblies are used to prevent backflow and protect water supplies. City codes, county codes, and Washington State regulation (WAC 246-290-490) require that these prevention assemblies be tested annually by a certified Washington State Backflow Assembly tester. Our certified team will test your backflow device, repair it if necessary, and send the required reports to the local water company.

Brimstone's backflow testing includes:

  • Full device examination
  • Examination of shut off valves, check valves, and relief valves
  • Exercise and lubrication
  • Reporting to owner and local water authority
