A check valve at the discharge of a pump is essential to prevent backflow, ensuring that the fluid only moves in one direction—away from the pump. This protects the pump from potential damage caused by reverse flow, which can lead to cavitation or loss of prime. Additionally, it helps maintain system pressure and efficiency by preventing fluid from draining back into the pump when it is not operating. Overall, a check valve enhances the reliability and performance of the pumping system.

If you have any water at all coming into the sump, there will always be a little in the bottom unless it stays dry long enough for it to evaporate.

What are the Advantages of reciprocating pumps?
A reciprocating pump is basically a piston in a cylinder with 2 check valves in ports in front of the piston. When the piston is moving back in the cylinder, a check valve allows fluid to fill the cylinder from the intake port, while the discharge port is blocked by its check valve. When the piston goes back the other way, the check valve in the discharge port allows fluid to pass while the check valve in the intake port closes.
How can I prevent air lock on a submersible sump pump?
To prevent air lock in a submersible sump pump, ensure that the pump is fully submerged in water and that the discharge pipe is properly installed without any sharp bends or high points that could trap air. Regularly check and maintain the pump to ensure it is free of debris and that the float switch operates correctly. Additionally, consider installing a check valve in the discharge line to prevent backflow and potential air trapping. If air lock occurs, you can manually release the trapped air by tilting the pump or using a hose to direct water into the discharge line.
