The Goodman 20201802 Condensate Drain Hose is a genuine OEM tube designed for the WGFM295090V5CAA high-efficiency gas furnace and related Goodman/Amana condensing models. It carries acidic condensate from the drain trap and collection points to the drain line. Over time, factory hoses can crack, harden, or clog — this exact-fit replacement restores clean, leak-free drainage.
OEM vs. Generic: The 20201802 is pre-cut to the correct length with the proper inside diameter to seat firmly on the furnace's barbed fittings. Generic bulk tubing often has the wrong ID, slips off under thermal cycling, or kinks in the tight cabinet routing. The OEM hose drops in without guesswork and keeps warranty coverage intact.
Install difficulty: Easy (1/5). Power down the furnace, pull the old hose off its barbed fittings, and press the new hose fully onto each fitting until seated. Secure with the original clamps if present. Most jobs take under 10 minutes. Run a heat cycle afterward and check for drips at each connection.
