Common symptoms this part fixes

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

  • Water leaking from heater port or unused fitting
  • Heater assembly weeping at plug location
  • Missing or stripped drain/sensor port plug
  • Corrosion or failure of existing plug causing slow drip

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

Before you buy — quick checklist

  • Confirm your existing plug uses 1/8"-27 NPT threading — do not assume based on visual size alone
  • Inspect the heater tube port threads for damage before installing the new plug
  • Verify this is a plug port and not a sensor or pressure switch port requiring a functional component
  • Check whether your heater manufacturer requires a specific plug material — stainless steel is appropriate for most spa environments

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