Common symptoms this part fixes

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

  • Heater union leaking at plumbing connection
  • Water dripping from heater inlet or outlet
  • Slow drip that worsens under pressure
  • Cracked or split tailpiece body
  • Cross-threaded union that won't seal
  • Visible stress fractures around buttress thread

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

Before you buy — quick checklist

  • Confirm your existing tailpiece uses 2-inch male buttress threads — not NPT or SAE
  • Measure the slip socket side to verify 2-inch slip (not 1.5-inch)
  • Inspect the mating union nut and o-ring — replace o-ring at the same time to ensure a leak-free seal
  • Check whether your heater union body (the union nut and collar) is also damaged — a cracked tailpiece sometimes indicates a harder impact or overtorque event
  • Confirm this is a Magic Plastics union assembly — buttress thread pitch and profile must match your existing union nut

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