Goodman 20201901 Condensate Drain Hose Tube

The Goodman 20201901 drain hose tube is the OEM condensate line that routes acidic condensate away from the drain trap and collector box on the GKS91155DXAG high-efficiency furnace. Over time, factory drain hoses can crack, harden, or develop biofilm blockages that back up condensate and trip the furnace on a pressure-switch fault. Replacing a worn hose with the correct OEM tube restores proper drainage and prevents water damage around the unit.

Specifications

OEM Part Number: 20201901
Component: Condensate drain hose / tube
Fits: Goodman GKS91155DXAG condensing furnace
Material: High-temperature flexible condensate tubing
Pre-cut and formed to factory routing

OEM vs. Generic

The OEM Goodman hose is molded to the correct inner diameter and length for a slip-fit connection at both ends — no clamps guesswork, no kinks. Generic bulk tubing can be the wrong ID, leading to leaks or restricted flow. OEM ensures the drain path matches the furnace's original design pitch.

Installation Difficulty

Easy (1/5). Slip off the old hose, push the replacement onto the same fittings, and verify a downhill run to the trap. No special tools required. Power and gas off before servicing.
