How to Fix / Troubleshooting

Safety first: Turn off power and close suction and return valves to isolate the pump. Allow system pressure to drop before disassembly.

Steps to replace seal:

  • Remove motor from wet end: Unbolt the Jacuzzi motor from the pump housing and separate carefully.
  • Remove impeller: Hold the motor shaft and unscrew the impeller. Note direction of threads.
  • Extract old seal: Remove both rotating and stationary halves of the mechanical seal from the impeller and seal plate.
  • Install new seal: Press the new stationary seat into the seal plate and the rotating face onto the impeller, handling only the edges and keeping faces clean.
  • Reassemble: Reinstall impeller, reattach motor to housing, open valves, prime, and test for leaks.

Always use a Jacuzzi-compatible mechanical seal kit specified for your pump model.
