Sta-Rite pool pump leaks water between the pump housing and the motor, often forming a puddle under the motor.

Safety: Turn off power and close suction and return valves before disassembling the pump.

• Disassemble wet end: Remove Sta-Rite pump housing bolts and separate the volute from the seal plate. Remove the impeller by holding the motor shaft and unscrewing the impeller.
• Remove old seal: Carefully remove both halves of the mechanical seal: the rotating carbon ring on the impeller and the stationary ceramic seat in the seal plate. Do not scratch the seal surfaces.
• Install new Sta-Rite seal: Press the new ceramic seat into the seal plate using a clean cloth and even pressure. Slide the new rotating half onto the impeller shaft, avoiding touching the polished faces with bare fingers.
• Reassemble pump: Reinstall the impeller, seal plate, and volute. Tighten bolts evenly. Reopen valves, prime the pump, and check for leaks.
• Prevent recurrence: Avoid running the pump dry and ensure proper priming to extend seal life.
