4-4.2 Back Flushing
The pump should be back flushed with municipal water after salt water or other debris have entered the pump.
1. Remove suction strainers.
Remove the suction strainers so they are not blown out of the pump.
2. Open transfer valve
(if applicable).
Hold the transfer valve clapper, in the second stage volute entrance, open so debris is not trapped behind it.
3. Pump water.
Pump fresh, clean water through all of the inlets and outlets, until you see only clear water.
4. Open & close valves.
Open and close all discharge and intake valves to flush them with clean water.
5. Activate primer.
In the case of salt water pumping, activate the primer to get clear water through the primer valve and pump.
6. Activate pressure relief valve.
Activate the pressure relief valve with the pilot valve to flush that system, and move the transfer valve from
volume to pressure a few times (if the pump is so equipped).

Flush the pumping system after pumping dirty, contaminated, or salty water.
1. Supply clean, fresh water.
Supply clean, fresh water to the pumping system.
