Before you buy — quick checklist

Confirm your heater is a HydroQuip Double Barrel model before ordering — this kit is not universal
Locate your heater model number (typically stamped on the heater housing label) and verify it matches this kit's fitment
Inspect whether the barb, the hose, or both are damaged — this kit covers the barb fitting only
Check the existing hose ID to confirm 3/4 inch compatibility before installing new barbs
Turn off power and water supply to the spa before inspecting the fitting

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