The Goodman 20201901 Condensate Drain Hose Tube is a genuine OEM drain line for the GCH950704CXAD gas furnace and compatible Goodman/Amana 90%+ AFUE equipment. This molded hose manages condensate flow within the sealed-combustion drainage system, keeping water moving away from the heat exchanger and inducer. Replacing a brittle or leaking original restores proper drainage and clears intermittent pressure-switch and drain-related fault codes.
OEM vs. Generic: The OEM hose arrives pre-bent to the factory routing with the correct barb diameters, so it seats securely without adapters. Generic replacements rarely match the molded bends and can chafe or kink against cabinet components. For reliable, leak-free drainage, choose the genuine Goodman part.
Install Difficulty: Easy (1/5). Roughly a 15-minute swap. Power down, drain residual condensate, match the original bend orientation, and re-secure both clamps.
