The Goodman 20201901 Condensate Drain Hose Tube is a genuine OEM replacement for the GMV90703BXBA condensing gas furnace and compatible Goodman/Amana models. This pre-formed tube carries acidic condensate between the furnace's collector box, pressure-switch ports, and drain trap. Its factory-molded shape ensures the correct bend radius so the line drains freely without kinking, sagging, or pulling off its fittings — issues that commonly cause water leaks and inducer/pressure-switch lockouts.
This factory-original 20201901 is shaped to Goodman's exact specification, so it clears internal components and seals cleanly on every barbed fitting. Generic hose requires cutting and hand-forming and tends to kink or leak over time. Choose OEM for a leak-free, drop-in fit.
Very Easy (1/5). Plan on 5–10 minutes: shut off furnace power, remove the old hose from its connection points, and firmly seat the new tube onto each barb. Verify there are no kinks and that condensate flows to the trap before restarting.
