The Goodman 20201802 is a genuine OEM condensate drain hose tube designed for the GCV90704CXBA high-efficiency gas furnace and compatible GCV90-series units. This flexible tube routes acidic condensate between the collector box, drain trap, and inducer assembly. Over time, factory hoses can harden, crack, or clog with biofilm and scale — restricting flow and causing water backups that trip the pressure switch and shut the furnace down.
Genuine Goodman tubing is cut to the exact factory length with the correct inner diameter to slip over OEM barbs without kinking. Generic hose often has the wrong bore, leaks at the fittings, or collapses under the furnace's internal draft. The OEM 20201802 guarantees a leak-free, correctly routed connection.
Very Easy (1/5). Replacement takes about 10 minutes. Power off the furnace, slide the old hose off the barbs, and press the new tube fully onto each fitting. Verify there are no kinks and that condensate flows freely to the trap. No tools required.
