The Goodman 20201802 is a genuine OEM condensate drain hose tube for the Amana/Goodman AMH950904CXAC and compatible high-efficiency gas furnaces. This pre-formed tube routes acidic condensate between the drain trap, inducer housing, and drain outlet. Over time, factory hoses grow brittle, kinked, or clogged with scale — leading to water leaks, trap overflow, and pressure-switch lockouts. Replacing worn hoses during any drain-system or trap service restores reliable drainage.
The OEM hose is cut and formed to the exact factory length and bend radius for a no-guess fit. The generic equivalent is a compatible-diameter tube at the lowest cost, ideal when you can trim to length. Both handle acidic condensate at furnace operating temperatures.
Easy (1/5). A 5–10 minute job: power off the furnace, slip the old hose off its barbed fittings, and press the new hose on. Confirm a snug, leak-free connection and clear water flow on the first cycle.
