Goodman 20201802 Condensate Drain Hose Tube

The Goodman 20201802 is a genuine OEM condensate drain hose/tube for the GKS90453BXAA 90%+ AFUE gas furnace. High-efficiency condensing furnaces route acidic condensate from the secondary heat exchanger and collector box through a network of molded hoses to the drain trap. Over time these hoses harden, kink, or grow biofilm and slime that restrict flow — leading to water leaks, tripped pressure switches, and nuisance shutdowns. Replacing a tired hose is one of the cheapest, highest-value pieces of furnace maintenance.

Part number: 20201802
Type: Molded condensate drain hose / tube
Fits: Goodman GKS90453BXAA and compatible GKS9 furnaces
Material: Flexible, condensate-rated polymer
Equipment: Gas furnace condensate system

OEM vs. Generic

This hose is molded to the specific length and bend of the GKS90453BXAA condensate path. Generic tubing must be cut to guess and can kink at the bends where the OEM part is pre-formed, so the factory hose maintains proper drainage slope and clears water reliably.

Installation Difficulty: Easy

Rated Easy (1 of 5). Power down the furnace, slide the old hose off its barbs, seat the new hose fully on each fitting, and confirm there are no kinks. Under 15 minutes with no special tools. Pour water through afterward to verify free drainage.
