Why is water leaking from my pool pump?

The impeller spins on the motor shaft and creates water pressure. If it gets damaged by lodged debris or simply worn from long use, the impeller can become the source of a water leak. You will need to remove the motor from the wet end of the pump in order to inspect and replace the impeller.

Why is my filter pump leaking?

What causes a mechanical seal to fail on a pump?

Choked flow causes recirculation within the pump, which generates heat and promotes a seal failure. Dry Running & Improper Venting of Seal: A vertical pump is the most susceptible since the mechanical seal is positioned on top. If you have improper venting, air can get trapped around the seal and won’t be able to evacuate the stuffing box.

Why is the check valve on my sump pump leaking?

It’s common for check valves to develop leaks over time. It can be either due to a failing internal valve or loose connections. Most high-end sump pumps will have built-in check valves to prevent the backwash of pumped out sump water. It also prevents sewage water from getting back into the pump.
