Common symptoms this part fixes

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

  • Leaking at pump inlet or outlet connection
  • Cracked or broken elbow fitting causing water loss
  • Excessive flow restriction due to sharp-bend elbow
  • Turbulence noise at pump connection
  • Split or stress-fractured union body from overtightening or freeze damage

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

Before you buy — quick checklist

  • Confirm your existing elbow is 2" FBT x 2" slip — measure pipe OD and check thread type before ordering
  • Inspect whether your current fitting is a sweep (gradual bend) or a standard sharp 90 — this is a sweep design
  • Check that the union nut and tail piece from your existing assembly are compatible or plan to replace the full union set
  • Verify the fitting material is compatible with your existing plumbing (PVC schedules and chemical treatments)
  • Confirm there is enough clearance in your equipment bay for the swept elbow geometry — sweep elbows have a larger turn radius than sharp elbows

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

Install difficulty: Medium — Some experience neededTypically 30–60 minutes
