The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate drainage component for the Goodman ACV90905DXBB high-efficiency furnace and related 90%+ AFUE models. This heavier-duty drain tube carries condensate from the furnace's internal trap and collector assembly to the drain line, protecting the heat exchanger area from standing water and keeping the pressure-switch circuit clear.
This OEM hose is sized to Goodman's exact specifications for diameter, wall thickness, and routing length, ensuring a leak-free seal at every connection. Universal replacement hose frequently mismatches the fitting size and can collapse under heat, allowing condensate to weep onto the burner compartment. Choosing genuine Goodman tubing avoids callbacks and water damage.
Easy (1/5) — Shut off power, detach the old tube from the trap and outlet, install the replacement, and re-secure the clamps. Typical replacement time is 15–20 minutes with no special tools.
