Goodman 20201802 Condensate Drain Hose Tube

The 20201802 is a genuine OEM condensate drain hose tube for the Goodman GCH90905DXAA high-efficiency gas furnace. This flexible drain line carries acidic condensate between the collector box, drain trap, and pressure-switch ports. Because it handles corrosive condensate and is routed through tight cabinet bends, the hose can harden, crack, or clog over time — leading to water leaks and pressure-switch faults. Replacing it with the correct factory tube restores proper drainage and sealing.

Specifications

Part number: 20201802
Type: Flexible condensate drain hose / tube
Fits: Goodman GCH90905DXAA and compatible furnaces
Material: Condensate-rated flexible tubing
Application: Collector box / trap / pressure-switch drain routing
Brand: Goodman OEM

OEM vs. Generic

The OEM Goodman hose is cut to the correct length with the right inside diameter and bend radius, so it seats on the barbed fittings without leaks or kinks. Generic bulk tubing can be substituted by experienced techs, but incorrect ID or length risks slip-offs and leaks — direct-fit OEM is the safe choice.

Install Difficulty

Easy (1/5). Slide the old hose off the barbed fittings and push the new one on; secure any clamps. Under 15 minutes. Verify the routing has no low spots that could trap water or air.
