The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM pre-formed drain line for the AMVC951155DXAA high-efficiency furnace. This tube carries acidic combustion condensate between the collector box, trap, and drain outlet. Over time factory hoses can harden, kink, or clog with biofilm, causing water leaks, overflow, and pressure-switch faults. Replacing worn hoses during service keeps the condensate path flowing freely and the furnace running without error codes.
This genuine OEM hose is molded to the exact length and bend radius your furnace requires, so it seats on the factory barbs without kinking. Generic bulk tubing must be cut and routed by hand and can pinch in tight cabinets, restricting flow. OEM ensures a proper, leak-free fit.
Easy. The hose slides onto barbed fittings and is secured with clips — no tools needed. About 5–10 minutes. Power down, note the routing of the old hose, then transfer the new one and confirm the trap holds water on restart.
