The Goodman 20171701 Condensate Drain Trap is the OEM drainage component for the GMH950704CXAD 96% AFUE condensing furnace. High-efficiency furnaces extract latent heat from combustion, producing acidic condensate that must be drained safely. This factory trap maintains the proper water seal that blocks flue-gas leakage while allowing condensate to flow to the drain.
This genuine Goodman OEM trap is molded to match the furnace's exact port geometry and seal depth. Generic traps rarely align with the cabinet ports and can leak combustion gases or crack under the acidic condensate. The OEM part guarantees a leak-free, code-compliant fit.
Easy to Moderate (2/5). Disconnect the drain lines, remove the old trap, prime the new trap with water to establish the seal, and reconnect. Verify no leaks at first firing. Plan 20–30 minutes.
