Goodman 20201802 Condensate Drain Hose / Tube

The Goodman 20201802 is a genuine OEM condensate drain hose (tube) sized and shaped for the GCH90904CXAA high-efficiency gas furnace. It routes acidic condensate between the inducer, collector box, drain trap, and pressure-switch ports. Over time, factory hoses harden, crack, or clog with sediment and biofilm — leading to water leaks, pressure-switch faults, and no-heat lockouts. Replacing a suspect hose during trap or inducer service restores a reliable, leak-free drain path.

Specifications

Function: Condensate drain / connection tubing
Fits: Goodman GCH90904CXAA condensing furnace
Material: High-temperature flexible tubing
Application: Trap, inducer, and pressure-switch routing
OEM Part Number: 20201802

OEM vs. Generic

The exact inner diameter, length, and bend of this hose are matched to the GCH90904CXAA cabinet layout. The genuine Goodman OEM hose slides onto the factory barbs for a secure seal, while generic tubing may kink or leak at the fittings. Given its low cost and safety role, OEM is the smart choice.

Installation Difficulty

Easy — slip-fit onto the factory ports, no tools typically required. Confirm the routing matches the original, avoid kinks, and check for leaks after refilling the drain trap.
