Before you buy — quick checklist

  • Confirm your existing pump is rated 115V — do not assume based on spa brand alone
  • Verify 0.75 HP on the motor nameplate label before ordering
  • Confirm single-speed wiring at the controller — this pump has no low-speed winding
  • Check discharge orientation (front vs. top) against your current plumbing layout
  • Measure your existing union fittings to confirm they will mate with WBH100 connections
  • Note whether your spa uses a dedicated bath/whirlpool circuit or a shared pump circuit

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