The Goodman 20201802 Drain Hose Tube is a genuine OEM condensate drain component engineered for the Goodman ACV90905DXBB furnace and compatible high-efficiency gas furnace platforms. This flexible drain tube routes condensate away from the secondary heat exchanger and collector box, helping prevent water backup, freeze-ups, and nuisance pressure-switch lockouts that occur when drainage is restricted.
Genuine OEM tubing is molded to the exact bend radius, length, and connection diameter Goodman specifies, so it seats on the collector box and drain trap without leaks. Generic aftermarket hose often requires trimming and can kink or loosen over time, leading to slow leaks and water-sensor faults. For reliable condensate management, OEM is the safe choice.
Easy (1/5) — Power down the furnace, remove the worn hose, slide on the replacement, and secure the clamp. Most homeowners complete this in under 15 minutes. No special tools required.
