HYDRANT FLOW TESTING

TESTING APPLICATIONS: HYDRANT FLOW TESTING

Hydrant flow tests are conducted to determine water availability in planning for firefighting activities, fire sprinkler systems or domestic water demand. The tests are also useful in determining the general condition of the water distribution system by detecting closed valves or wall deposits. A well-maintained water system enables firefighters to extinguish flames and prevent large- scale damage or loss of life.

HOW OFTEN DO I TEST A HYDRANT?

  • AWWA recommends flow testing all areas at least every 10 years. (AWWA M17).
  • NFPA requires flow testing of underground and exposed piping at least once every 5 years (NFPA 291)
