OEM Goodman Condensate Drain Trap for WGFM195090S5DAC — 20171701

Goodman 20171701 Condensate Drain Trap

The 20171701 is the genuine OEM condensate drain trap for the Goodman WGFM195090S5DAC 95% AFUE condensing gas furnace. High-efficiency furnaces pull latent heat from the flue gas, producing acidic condensate that must be drained safely. This factory trap holds a water seal that lets condensate flow out while blocking flue gases and combustion-air pressure from escaping through the drain line — a job a simple hose cannot do.

• Function: Water-sealed trap for secondary heat exchanger condensate
• Material: Molded polymer, corrosion-resistant to acidic condensate
• Ports: Factory-matched inlet/outlet barbs for OEM drain hoses
• Fits: Goodman WGFM195090S5DAC condensing furnace

OEM vs. Generic

The OEM trap is molded to the exact port spacing and hose diameters of this furnace, so the water seal and pressure-switch reference stay correct. Generic traps often leak air, throw pressure-switch faults, or won't line up with the factory hose kit. For reliable draining and no nuisance lockouts, stay with OEM.

Installation Difficulty: Easy–Moderate (2/5)

Power down the furnace, disconnect the drain hoses, and remove the old trap. Flush it first if it's simply clogged — many are only blocked. Prime the new trap with water before reconnecting so the seal is active on the first burn. Verify hoses seat fully on each barb to avoid leaks.
