The Goodman 20201901 Condensate Drain Hose is a genuine OEM tube designed for the GMH950703BXAC high-efficiency furnace. It carries corrosive condensate through the drain system with the correct routing and bend, helping prevent kinks, backups, and pressure-switch lockouts common when a worn hose collapses.
The OEM hose arrives pre-formed to the factory shape and length, so it clears internal components without kinking. Generic straight tubing is cheaper but can sag or pinch, restricting flow. For a molded drain routing like this, OEM is recommended for trouble-free drainage.
Easy (1.5/5). About 10–15 minutes. Cut power, note the routing of the old hose, remove it from its fittings, and press the new hose on in the same path. Confirm free drainage and no kinks before restoring power.
