Hot Water Recirculation Pumps - DIY Plumbing Advice

Pumps located at a point of use (e.g., under a sink) do not require or use a dedicated hot water return line. They return the non-hot water into the cold water supply line until the hot water is sensed at the fixture (the water is returned to the hot water heater via the cold line). Because the pump is located right at the fixture, hot water is
