The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube for the GCH950704CXAB and compatible Goodman/Amana high-efficiency furnaces. Cut to a precise 23-inch length, this flexible hose routes acidic condensate from the furnace collector box or trap to the drain line with the correct reach and bend radius, ensuring a leak-free, kink-free connection. Swapping out a brittle, clogged, or leaking hose restores drainage and prevents water backups, pressure-switch faults, and no-heat lockouts.
The OEM 20201902 is factory-cut to 23 inches with the correct inner diameter, so it fits the furnace ports and reaches the drain without splicing or adapters. Generic bulk tubing must be measured and trimmed, and the wrong ID can leak at the connection. OEM removes the guesswork and guarantees fit.
Easy. Remove the old hose, push the 23-inch replacement onto the same fittings, and secure the clamps — roughly 5–10 minutes with no special tools. Verify a clear, downhill drain path before restarting the furnace.
