Common symptoms this part fixes

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

  • Weak or no water flow from jets
  • Pump runs but produces little to no pressure
  • Visibly cracked, chipped, or broken impeller vanes
  • Grinding or rattling noise from pump housing
  • Pump cavitating under normal operating conditions

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

Before you buy — quick checklist

  • Confirm your pump is the LX WTC50M — check the label on the pump housing
  • Measure your existing impeller: verify 2-3/5" sealed length and 4" outer diameter before ordering
  • Inspect the pump shaft and seal for damage — a worn seal should be replaced at the same time
  • Check that your pump's horsepower rating matches 1.0 HP
  • Drain and de-energize the spa completely before beginning any disassembly

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