Goodman B2810703 Drain Trap & Hose Kit

The Goodman B2810703 is a genuine OEM condensate drain trap and hose kit for the GMPN120-5 high-efficiency gas furnace. In a condensing furnace, the secondary heat exchanger produces acidic condensate that must drain freely while the trap maintains a water seal against flue-gas leakage. This complete kit includes the molded trap body and pre-cut drain hoses, restoring proper drainage and preventing nuisance pressure-switch lockouts caused by a clogged or cracked trap.

Specifications

OEM Part Number: B2810703
Type: Condensate drain trap with hose kit
Compatibility: Goodman GMPN120-5 condensing gas furnace
Includes: Trap assembly + pre-cut drain tubing
Function: Drains condensate and maintains flue-gas seal

OEM vs. Generic

The OEM kit matches Goodman's exact port angles, hose lengths, and trap geometry — critical for correct pressure-switch operation. Generic traps often require improvised fittings and can trigger false pressure faults. The complete OEM kit installs cleanly with no adapters.

Installation Difficulty

Moderate (3/5). Power down the furnace, remove the old trap and hoses, install the new assembly, prime the trap with water, and confirm free drainage. Routing the hoses correctly is the key step. Roughly 30–45 minutes.
