Pump leaks water between the pump housing and the motor mounting plate.

Safety first: Turn off power at the breaker and close suction and return valves before disassembling the pump. Relieve filter pressure.

• Confirm leak location:
  • Observe water dripping from the seam between the pump housing (wet end) and motor, not from plumbing joints.
• Disassemble pump wet end:
  • Remove pump lid and basket.
  • Unbolt the clamp or bolts connecting the motor to the pump housing.
  • Remove the motor/impeller assembly.
• Replace mechanical seal:
  • Remove the impeller and old mechanical seal components from the seal plate and impeller.
  • Install a new Jandy-compatible mechanical seal kit, taking care not to touch the seal faces with bare fingers.
• Reassemble and test:
  • Reassemble pump, restore valves to normal, prime, and run the pump while checking for leaks.
