The Goodman 20171701 Drain Trap is a genuine OEM condensate trap assembly for the GMS951155DXA high-efficiency gas furnace and other GMS95-series models. In a 95% AFUE furnace, the secondary heat exchanger produces acidic condensate that must drain freely while the trap holds a water seal to block flue gases from escaping the drain line. A cracked, clogged, or algae-fouled trap leads to water leaks, pressure-switch faults, and lockouts.

Specifications

OEM Part Number: 20171701
Type: Condensate drain trap assembly
Function: Condensate drainage with flue-gas water seal
Application: 95% AFUE (condensing) furnace drain system
Fits: Goodman GMS951155DXA and compatible GMS95 furnaces

OEM vs. Generic

The OEM drain trap matches the factory port locations, barb sizes, and internal geometry, so it drops in without adapters and maintains the correct water-seal height. Generic traps often require refitting tubing and may not seat with the furnace's pressure-switch hoses, risking nuisance faults. For a condensing furnace, the genuine trap saves labor and avoids callbacks.

Installation Difficulty: Moderate

Rated 3 of 5. Power down, disconnect the drain and pressure-switch tubing, remove the old trap, and install the new assembly with hoses routed exactly as before. Prime the trap with water, then run a full cycle and check for leaks and correct pressure-switch operation. Professional installation recommended.

Route condensate to an approved drain and follow all local plumbing and combustion codes.
