1. Install a smaller pump.
• Consult licensed water systems professional contractor for sizing.
2. Add additional length of drop pipe to place pump lower in well.
3. Install a Franklin Pumptec or similar electronic run-dry sensor.
4. Install a float-less liquid level control to work with the pressure switch.
5. Place a flow control valve in the discharge line upstream from the pressure switch to restrict output.
• A pressure tank with a bonded diaphragm, air cell, or water bag is recommended.

MAINTENANCE
Check Valve Replacement
Risk of damage to pump or other equipment.
• Fluid draining back through the pump can cause the pump to rotate backwards. If pump/motor starts
during this time, damage to the pump can occur.
Most 4-inch submersible pumps come standard with an internal check valve to prevent water back
flow.
To remove:
1. If the pump discharge has a snap ring
blocking the check valve, remove using a
standard size snap ring tool.
2. Unscrew the check valve assembly (clock-
wise) using a T-handle wrench, sold sepa-
rately.
NOTE: Check valves are reverse (left-hand) threaded.
For reassembly, tighten the check valve to 15 inch-pounds.
