This genuine Goodman 20201902 is a 23-inch condensate drain hose tube engineered for the Goodman GKS90704CXAC high-efficiency gas furnace and compatible GKS90 series units. It carries condensate from the secondary heat exchanger and inducer assembly to the drain trap, maintaining proper drainage and preventing the water backup that leads to pressure-switch faults.

OEM Part Number: 20201902
Brand: Goodman (Genuine OEM)
Length: 23 inches
Fits Model: GKS90704CXAC and compatible GKS90 series furnaces
Component Type: Condensate drain hose tube
Material: Flexible high-temperature condensate-rated tubing

OEM vs. Generic

The 23-inch OEM length is pre-cut to reach exactly where your furnace's drain routing requires, so there is no guesswork. Generic bulk tubing must be measured and trimmed on-site and frequently kinks at tight bends, restricting flow. The genuine Goodman 20201902 preserves factory routing, warranty coverage, and reliable drainage.

Install Difficulty: Easy (1/5)

Straightforward slip-on swap. Cut power, detach the old 23-inch hose at both ends, install the new tube, seat fully, and clamp. Confirm free condensate flow before returning the furnace to service.
