The Goodman 20201901 Condensate Drain Hose Tube is a genuine OEM component for the Goodman GCH950704CXAA high-efficiency furnace and compatible units. This drain tube carries condensate from the heat exchanger and collector box to the trap, protecting the burner compartment and control board from moisture damage. It is the correct replacement when the original line is cracked, brittle, clogged, or leaking, or when you are rebuilding the condensate assembly during routine service.
OEM 20201901 tubing is formed to the precise routing, length, and connector diameters specified for this furnace, ensuring a leak-free seal at every barbed joint. Generic hose may fit loosely, harden faster near the heat exchanger, or require field modification that voids the tight factory seal. Choosing OEM means fewer callbacks and reliable long-term drainage.
Easy (1 of 5). Plan on 10–20 minutes. Power down the furnace, remove the access panel, detach the old tube from its fittings, route the new tube along the same path, and press it fully onto each connection. Clear the trap while you are in there and run the furnace to confirm condensate drains without pooling.
