The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate drainage component engineered for the Goodman GKS90704CXAF gas furnace and compatible high-efficiency models. This flexible hose routes acidic condensate away from the heat exchanger and inducer assembly, protecting internal components from corrosion and preventing water pooling inside the furnace cabinet. A cracked, brittle, or clogged drain hose is one of the most common causes of nuisance lockouts and pressure-switch faults, making this an inexpensive but critical replacement part.

OEM vs. Generic

This is a genuine Goodman OEM part, molded to the exact bend radius and fitting diameter of your furnace's drain trap. Generic aftermarket hoses often use thinner walls that kink at factory routing points or fail to seal against the OEM barbed fittings, leading to slow leaks. Choosing OEM ensures a leak-free fit the first time and preserves any remaining manufacturer warranty coverage.

Installation Difficulty

Easy (1 of 5). Most homeowners can complete this in under 15 minutes with the furnace powered off. Slip the old hose off the drain-trap and inducer barbs, route the new hose along the same path, and secure any clamps. No tools beyond a nut driver or pliers are required. If you're uncomfortable working near the gas valve or heat exchanger, consult a licensed HVAC technician.
