The Goodman 20201901 condensate drain hose tube is a genuine OEM replacement that channels acidic combustion condensate through the drainage system of the ACVC90905DXAB 90% AFUE gas furnace. This longer routing tube connects key drainage points in the cabinet; when it kinks, hardens with age, or detaches, the result is water leakage, a tripped pressure switch, and furnace lockouts. Installing the factory-spec hose restores proper drainage and reliable heating.
The genuine Goodman 20201901 is pre-formed to the exact length and bend radius your furnace requires, so it routes cleanly without kinks or stress on the fittings. Generic tubing must be field-cut and frequently develops slip-offs or restrictions. OEM guarantees the correct inner diameter and a secure, leak-free seal.
Easy (DIY-friendly). Plan on 15-25 minutes. Switch off furnace power, detach the worn tube from its barbed connections, route the new 20201901 along the same path, and seat it firmly on each fitting. Verify drainage with a quick water test before restoring power.
