Pentair 355222S WaterFall Specialty Pump Motor (AF-180 / AFP-150 / AFP-180)

Common Reasons to Replace the Motor

  • Motor hums but won’t start, or trips breaker on start-up
  • Overheating, thermal shutdown, or intermittent operation
  • Loud bearing noise (grinding/squealing)
  • Loss of power, slow start, or inconsistent performance on a water feature line
  • Evidence of water intrusion/corrosion at the motor

Installation Notes

  • Shut off power at the breaker and verify power is off before service.
  • Confirm wiring is configured correctly for 115V vs 230V before energizing.
  • When replacing a motor, it’s strongly recommended to replace the mechanical shaft seal and any disturbed O-rings/gaskets.
  • Inspect the seal plate, diffuser, and impeller for heat damage if the pump has run dry.
  • After reassembly, prime the pump fully and check for leaks at the seal plate and unions.

Maintenance Tips

  • Fix wet-end leaks quickly—persistent moisture around the motor shortens motor life.
  • Keep baskets/strainers clean to reduce cavitation and overheating.
  • Ensure adequate ventilation and avoid sprinkler spray or standing water at the equipment pad.
  • If the motor is cycling frequently, confirm automation programming and verify valves are not restricting flow.
