Genuine Goodman 20201802 Drain Hose Tube

This OEM Goodman 20201802 drain hose tube is a factory replacement for the Goodman GCH90703BXAB high-efficiency gas furnace. The hose routes acidic combustion condensate from the collector box and drain trap to the drain line. Over time, condensate exposure can cause the hose to harden, crack, or clog — leading to water leaks, pressure-switch faults, and nuisance lockouts. Replacing the hose restores reliable, leak-free drainage.

Specifications

OEM Part Number: 20201802
Part Type: Condensate Drain Hose / Tube
Function: Condensate routing to drain
Brand: Goodman
Fits: GCH90703BXAB gas furnace
Material: Condensate-resistant flexible tubing

OEM vs. Generic

This genuine Goodman OEM hose is pre-cut and molded to the correct length, inner diameter, and bend radius for your furnace. Generic tubing must be cut to fit and can kink or slip off the barbed fittings, causing leaks. The OEM part seats securely on the factory ports for a clean, drip-free connection.

Installation Difficulty

Easy (1/5). Slip the old hose off the fittings and press the new one on — no tools required in most cases. Power down the furnace, then check for leaks after restart.
