Before you buy — quick checklist

  • Confirm your existing pump is 230V — do not install on a 115V circuit
  • Match the horsepower rating on the old pump's motor label before ordering
  • Verify your spa uses a 48Y frame motor — measure or check the original pump label
  • Confirm two-speed wiring is present at the equipment bay before swapping
  • Check plumbing union size and type on your existing pump before disconnecting
  • Note the wet end inlet/outlet orientation to ensure the replacement fits your plumbing layout

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