The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM replacement hose for the GKS90704CXAC high-efficiency gas furnace and related Goodman/Amana models. This flexible tube carries acidic condensate between the secondary heat exchanger, drain trap, and outlet, and helps maintain the sealed pressure paths the furnace relies on. Over time these hoses harden, crack, kink, or clog with scale — leading to water leaks, pressure-switch faults, and nuisance shutdowns.

Specifications

Part Number: 20201802
Type: Condensate Drain Hose / Tube
Application: High-efficiency (condensing) gas furnace
Material: Flexible corrosion-resistant tubing
Fits Model: GKS90704CXAC and compatible Goodman furnaces
Equipment: Gas Furnace

OEM vs. Generic

The OEM 20201802 is cut to the correct length and diameter to route cleanly and seal to the factory trap and fittings. Generic tubing may be the wrong bore or too stiff, causing kinks, leaks, or loose connections that upset the furnace's pressure switches. The genuine part ensures a leak-free, drip-free drainage path.

Installation Difficulty

Easy (1.5/5). Slip the old hose off its barbed fittings and slide the new one on, matching routing so it does not kink. Power down the furnace, verify a tight fit at both ends, and confirm condensate drains freely with no leaks. A quick, DIY-friendly repair for most homeowners.
