Before you buy — quick checklist

  • Confirm your spa runs a HydroQuip Slipstream heating system before ordering
  • Verify your spa operates at 240V — do not install on 120V systems
  • Check that your system is rated for low flow operation; this is not a standard flow heater
  • Inspect existing heater housing for damage — if manifold or plumbing is cracked, additional parts may be needed
  • Note whether your HH or OH fault is caused by a failed sensor vs. a failed heater element — sensors are sold separately
  • Have your current heater assembly SKU or model number on hand to confirm cross-compatibility

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