1. Check Valve Located at the top of the pump to prevent back flow into pump and hold the head of water in the system. 2. Torque Arrestor Installed directly above Submersible Pump to protect pump and well components from starting torque damage.

Is there a check valve on a submersible well pump?
Check valves permit water flow only in one direction and are required on all submersible pump installations. … Some submersible pumps have built-in check valves, and are suitable for operation without an external check valve, provided the pump setting is not too deep.

Do sump pumps need backflow preventer?
To guard against this, plumbing authorities generally require that homes with traditional water powered sump pumps install a Reduced Pressure Zone (RPZ) backflow preventer. … Finally, further complicating matters, they reduce the pump’s power by restricting the water flow going to the pump.
