Before you buy — quick checklist

  • Confirm your spa model year is 2006 or newer before ordering
  • Verify your existing pressure switch part number matches 73995 before purchasing
  • Inspect the wiring harness and connector on the old switch — confirm terminal configuration matches before removal
  • Check whether the fault is the switch itself or a related component such as the ozonator or chemical feed line
  • If your spa is pre-2006, do not assume compatibility — confirm with your spa's service manual or a technician

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