The Goodman 20201902 23-inch Condensate Drain Hose Tube is the genuine OEM length of drainage hose used on the Goodman ACVC90704CXAB 96% AFUE condensing gas furnace. Cut and molded to a precise 23 inches, this tube carries condensate from the collector box and drain trap to the home's drain line. Because condensing furnaces continuously produce acidic water during operation, a properly sized hose is essential to prevent backups, overflow, and the pressure-switch lockouts that result from blocked drainage.
The OEM 20201902 arrives pre-cut to the exact factory length, so it routes cleanly without slack to trap water or tension to pull a fitting loose. Generic bulk hose must be measured and cut on site, and a hose left too long sags and forms low spots where condensate pools and freezes or grows biofilm. Choosing OEM removes the guesswork and matches the original drainage geometry.
Easy (1 of 5). Replacement takes about 10 minutes. Shut off power, loosen the clamps at both ends, pull the old hose, and install the 23-inch 20201902 along the same route. Reattach the clamps, restore power, and verify free condensate flow with no leaks before sealing the cabinet.
