Before you buy — quick checklist

  • Confirm your existing strainer body uses 1.5" male buttress threads — measure or check pump documentation before ordering
  • Verify the split nut configuration on your current strainer matches this design
  • Inspect whether the O-ring is included or if your current housing uses a different seal style
  • Check for any spa manufacturer-specific fittings that may require an exact OEM match
  • Note whether your existing strainer body is bonded into the plumbing or uses a slip/threaded connection

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