Goodman 20201802 Condensate Drain Hose Tube

The Goodman 20201802 is a genuine OEM condensate drain hose/tube designed for the GCH91155DXAA high-efficiency gas furnace and compatible Goodman/Amana models. In a 90%+ AFUE condensing furnace, the secondary heat exchanger produces acidic condensate that must be routed reliably to the drain system. This factory-molded tube is sized and shaped to fit the furnace's drain trap and collector connections without kinking or leaking.

Specifications

OEM Part Number: 20201802
Function: Condensate drain hose / tube
Material: Corrosion-resistant flexible tubing
Fits: Goodman GCH91155DXAA and compatible condensing furnaces
Equipment: High-Efficiency Gas Furnace

OEM vs. Generic

Because condensate is mildly acidic and routing geometry is tight, using the exact OEM tube prevents leaks that can damage the furnace base, control board, and floor. Generic tubing may be the wrong diameter or length, leading to slow drainage, trap airlocks, and pressure-switch faults. The OEM 20201802 drops in with no trimming or guesswork.

Installation Difficulty

Very Easy (1/5). Slip-fit connection at the drain trap and collector box; secure clamps if originally equipped. Power down the furnace, remove the failed hose, and seat the replacement fully. Confirm free condensate flow and check for leaks after restart.
