Similar to flushing your home’s pipes from debris that may collect over time, the District flushes fire hydrants by allowing water to run for short period of time. This process is known as hydrant flushing and it is an important element for the maintaining a healthy water system. By allowing water to travel out of the hydrant at a high speed and pressure, pipes are cleaned of natural debris that accumulates in the pipeline.
To flush a fire hydrant, staff opens the hydrant and allows water to flow out uninterrupted for 5-10 minutes. You can view an interactive map with flushing and valve exercising activities occurring in the District, click here.
