Pump Connection Kit (W/ Gasket)

Rheem Pump Connection Kit with Gasket – Engineered Interface for Recirculation Integration

The RTG20319AT Pump Connection Kit is a factory-engineered assembly used for integrating a recirculation pump into Rheem tankless gas water heating systems. Designed specifically to support dedicated recirculation loops or on-demand pump operations, this kit ensures proper hydraulic connectivity between the appliance and external circulation components.

Included in the kit are the necessary fittings and gasket to establish a sealed, corrosion-resistant connection, compatible with approved Rheem tankless models that support internal or external pump integration. The assembly is manufactured to maintain high-temperature sealing performance and long service life in high-cycle applications.

Primary Application

For use in conjunction with Rheem tankless gas water heaters where recirculation functionality is required. Ensures secure thermal and hydraulic performance when implementing a hot water return line system.

Component Specifications

• Part Number: RTG20319AT
• Kit Contents: Factory-supplied pump fittings, gasket, and threaded connectors
• Compatible Models: Select Rheem RTG-series tankless gas water heaters (consult model-specific literature for compatibility)
• Gas Type Compatibility: Natural gas and propane (when used with compatible appliance)

Installation Notes

Installation should be performed by a licensed technician. The kit must be assembled per Rheem engineering guidelines to ensure leak-free operation and compliance with local code. Over-tightening, cross-threading, or incorrect gasket seating can result in component damage or reduced system efficiency.

This assembly is not a universal fit for third-party appliances or water heating units not specified by Rheem. Always verify compatibility with system documentation prior to installation.

Performance Considerations

• Optimized Flow Dynamics: Designed to maintain consistent system head pressure and accommodate pump cycling.
• Seal Integrity: Gasket composition selected for resistance to chlorinated domestic water and thermal cycling.
• System Longevity: Precision-machined fittings reduce risk of scale accumulation and premature wear at the connection point.

Contractor Application Notes

For new installations or retrofits involving return loop piping, the RTG20319AT is required to complete the recirculation interface. The kit accelerates field assembly while maintaining factory integrity, eliminating the need for custom piping configurations or third-party fittings that may void warranty terms.
