Hot-Link is a quick, easy retrofit using the existing plumbing. Mount the valve under the sink and the pump at the water heater. The valve’s unique thermal disk technology sends cooled water back to the water heater so hot water lines remain hot. There’s no need to remove the Hot-Link valve from the piping to keep it clean. Our exclusive clean-in-place design makes short work of keeping the system operating properly. Download the Hot-Link brochure to get all the details.
