Over-the-water-heater: For this configuration, the pump is located above the water heater, and a check valve is located under the sink furthest away from the hot water heater. The pump pressurizes the hot side of the systems and, through the bypass valve under the sink, it pushes the hot water into the cold water system, creating a hot loop.

When the pump detects cold water in the line it sends it back to the water heater rather than into the sewers. Once the pump thermometer warms up from hot water it shuts off and starts to drain normally.

The valve at the furthest point allows previously hot water that is now cool to go into the cold water pipes backwards and the pump pushes hot water back into the hot pipes up to that valve. With an existing install, this is probably the easiest way to do it, but I prefer an install with a dedicated return to avoid getting the water from the ...
