Common symptoms this part fixes

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

  • Water leaking from pump shaft area
  • Wet motor housing or dripping beneath the pump
  • Burning smell from seal running dry
  • Visible mineral deposits or corrosion around pump shaft
  • Seal faces cracked or visibly worn on inspection

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

Before you buy — quick checklist

  • Confirm your LX pump model number matches the 56WUA500 seal fitment — check the label on the pump housing
  • Verify the existing seal is a mechanical shaft seal failure, not a union or housing O-ring leak
  • Inspect the pump shaft for scoring or pitting — a damaged shaft will destroy a new seal prematurely
  • Check that the seal spring and seat are also being replaced if heavily corroded
  • Confirm you have the correct tools for seal removal and installation — forcing a seal can damage the face

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