Common symptoms this part fixes

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

  • Active leak at pump volute drain port
  • Water pooling under pump housing
  • Failed or cracked drain plug allowing slow seep
  • O-ring deterioration causing seal failure at drain location

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

Before you buy — quick checklist

  • Confirm your pump is a Sta-Rite Dura-Jet model — check the label on the pump volute
  • Inspect whether the leak is at the drain plug location specifically, not at a union or seal
  • Check condition of the existing O-ring — replace it at the same time as the plug
  • Note whether the plug threads are intact or stripped before ordering, as a stripped volute boss is a separate repair

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