Condensate Drain Trap Replacement Kit

Rheem OEM Replacement Condensate Trap Kit for Tankless Gas Water Heaters

The Rheem RTG20319N Condensate Drain Trap Kit is a factory-authorized replacement part for use with select Rheem condensing tankless gas water heaters. This assembly is designed to collect and safely discharge condensate generated during combustion and heat exchange, helping maintain system performance and protect downstream components from corrosion or water damage.

This kit includes the molded condensate trap body and gasket required to restore proper condensate management within the unit. It is suitable for routine maintenance or when replacing a degraded or leaking trap on compatible models.

Kit Overview and Purpose

• Part Number: RTG20319N
• Application: OEM drain trap replacement for Rheem condensing tankless models
• Function: Condensate collection and drainage for safe discharge
• Included Components: Condensate trap assembly and gasket

System Compatibility

This kit is engineered for use with Rheem condensing tankless gas water heaters. Confirm compatibility using model-specific technical documentation. It is not suitable for non-condensing models or systems outside Rheem’s condensing series.

Installation Notes

Installation of this trap should be performed by a licensed technician familiar with tankless system internals. Replacement involves disassembly of the lower panel, removal of the existing trap assembly, inspection of the drain line, and correct seating of the new gasket and trap unit. All connections must be watertight and vented properly per the unit’s installation manual and local plumbing codes.

This component is subject to degradation due to acidic condensate. Regular inspection and replacement—especially in hard water or high-condensate environments—is essential to maintaining safe and efficient operation.

Key Product Attributes

• Corrosion-Resistant Materials: Designed to withstand exposure to acidic condensate typical of condensing appliances
• Factory Fit: OEM part ensures proper interface with Rheem assemblies, avoiding alignment or sealing issues common with non-genuine components
• Leak Prevention: Includes high-tolerance gasket for maintaining a reliable, watertight seal
• Low Profile Design: Compact geometry preserves internal unit clearance and drain routing

Contractor Notes

This kit should be stocked for any service call involving condensate management complaints, visible internal leaks, or routine maintenance on high-mileage tankless units. Proper trap function is critical to system reliability and prevents water damage to the burner compartment and electrical components. Always verify correct trap orientation and drain routing during installation.
