The Goodman 20201901 Condensate Drain Hose Tube is a genuine OEM replacement for the AMS950704CXAB high-efficiency gas furnace and compatible Goodman/Amana models. This pre-formed hose carries condensate between the secondary heat exchanger, drain trap, and drain outlet, holding the correct bend and length so water drains freely without pooling. Replacing an aged, cracked, or clogged hose eliminates leaks and prevents condensate backups that trigger pressure-switch lockouts.
The OEM Goodman 20201901 is molded to the exact length, diameter, and bend geometry for this furnace, ensuring a snug, leak-free fit on the factory fittings. Generic tubing requires hand-fitting and can kink or slip off, leading to callbacks and water damage. For dependable drainage, the matched OEM hose is the recommended choice.
Easy (1 of 5). Plan on 10–15 minutes: shut off furnace power, remove the old hose from its barbed connections and any clamps, route the new hose along the same path, and press it fully onto each fitting. Prime the drain trap and confirm there are no leaks before restoring power.
