Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Weak or reduced water flow from jets
  • Pump runs but jets have no pressure
  • Impeller visibly cracked, chipped, or worn
  • Cavitation noise (rattling or grinding) from pump housing
  • Pump overheating due to restricted flow
  • Spa not reaching target jet pressure after priming

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing impeller measures 3-5/8" seal length and 3-3/4" outer diameter before ordering
  • Verify your pump is rated at 1.0 HP — installing the wrong HP impeller will cause flow and pressure problems
  • Confirm your pump is an Aqua-Flo model — cross-reference the OEM part number 91693601 on your existing impeller or pump documentation
  • Inspect the diffuser and seal plate for wear while the pump is open — replace if damaged
  • Check the pump shaft seal condition before reassembly — a worn seal will leak after reinstallation

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
