Grundfos 595916 Pump
The Grundfos 595916 (Model UP15-10SU7P/TLC) is a heavy-duty, stainless steel hot water recirculating pump designed specifically for retrofit applications in residential systems lacking a dedicated return line. This 115V single-phase circulator utilizes the existing cold water line to loop thermal energy back to the water heater, ensuring instant hot water delivery at the furthest fixture. As a veteran-grade recirculation system, it features a 1/25 HP motor with built-in thermal protection and a broad liquid temperature range of 36°F to 150°F, making it a reliable solution for maintaining optimal domestic hot water system performance without the need for invasive plumbing overhauls.
For precise control and energy efficiency, the Grundfos Comfort System includes an integrated 24-hour programmable timer with 15-minute intervals and three operation modes: continuous, timer-controlled, and off. The pump housing is constructed from high-grade stainless steel (ASTM A351-CF8) to withstand corrosive open-loop environments, while the composite PES+30% GF impeller ensures long-term hydraulic integrity. Installation is streamlined with a 3/4" female NPT inlet and 3/4" male NPT outlet, allowing for direct mounting to the water heater discharge. Technicians looking for a bypass valve pump solution will appreciate the inclusion of the thermal bypass valve and hose kit, providing a comprehensive under-sink hot water kit that significantly reduces water waste and improves homeowner comfort.
Key Benefits- Retrofit-Ready: Engineered for homes without dedicated return lines, utilizing a patented thermal bypass valve to redirect cooled water.
- Enhanced Durability: Features a corrosion-resistant stainless steel pump housing and internal motor protection for high-cycles in open systems.
- Energy Efficient: Programmable timer allows for scheduled circulation, minimizing heat loss and reducing electrical consumption to approximately 25W.
- Complete Installation Kit: Includes the UP15-10SU7P/TLC pump, 10-foot line cord, bypass valve, and flexible connectors for rapid field deployment.
- Code Compliant: Certified to NSF-61 and NSF-372 standards for potable water safety.
Can this pump be used with a tankless water heater?
No, this specific Grundfos 595916 model is designed for use with tank-style water heaters only. Tankless units typically require a higher activation flow rate than this pump provides.
Where should the bypass valve be installed?
The bypass valve must be installed at the fixture furthest from the water heater in the hot water recirculation loop to ensure the entire line is serviced.
Is this pump compatible with PEX piping?
Yes, it is compatible with all standard residential piping including PEX, copper, and CPVC, provided the appropriate NPT adapters are used during the recirculation pump installation.
