Common symptoms this part fixes

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

  • Weak or no jet pressure despite pump running
  • Pump runs but water flow is significantly reduced
  • Impeller visibly cracked, chipped, or broken on inspection
  • Cavitation noise (rattling or grinding sound) from pump housing
  • Pool of water under pump with no seal leak found — impeller wear causing internal bypass

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

Before you buy — quick checklist

  • Confirm your pump is a Gecko Alliance Maelstrom model before ordering
  • Measure the outer diameter of your existing impeller — must be 3-3/4" (95mm) for correct fit
  • Verify your pump's horsepower rating matches 2HP on the motor label
  • Inspect the pump shaft and diffuser for damage before replacing impeller only
  • Check whether the impeller threads onto the shaft clockwise or counterclockwise before disassembly so you are prepared

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