Before you buy — quick checklist

  • Confirm your existing tee fitting is 3/4" RB x 3/4" RB — measure before ordering
  • Verify your spa's temperature sensor probe fits the port on this tee
  • Check that your current tee is cracked, leaking, or causing sensor misreads — the fitting and sensor are separate components
  • Confirm your spa is a Sundance brand unit and cross-reference your model's parts diagram if available
  • Inspect surrounding plumbing for additional damage before installing a new fitting
