Water: Part 3
Flushing hydrants is a maintenance activity that extends the life of the distribution system. Discharging sediment buildup in water mains delivers better quality water to customers. Meanwhile, the available water flow for fire protection is verified.
Valves are also found on hydrant stubs, so that if a hydrant needs replacing because it’s leaking, the water supply can be shut off to a hydrant at a hydrant valve (Figures 29-30).
