The process of opening fire hydrants to clean water mains

A hydrant flush refers to the process of opening fire hydrants to release water into the system, which serves multiple important purposes. One of the primary reasons for flushing hydrants is to clean water mains. This process helps remove sediment, rust, and other impurities that can accumulate in the pipes and affect water quality. By allowing water to flow freely from the hydrants, operators can ensure that the water distribution system remains clear and that the water supplied to consumers is safe and clean.

Additionally, flushing hydrants can help in testing and maintaining the hydraulic characteristics of the piping system. It can verify that water flows effectively and assess the performance of the fire hydrants themselves to ensure they function properly in the event of a fire emergency.
