How System Works:

The valve is installed under the sink farthest from the water heater where hot water takes the longest time to arrive.

No electrical outlet is required.

When the hot water supply line becomes cool, the adjustable thermostatic valve allows the cool water in the hot water supply line to flow into the cold water supply line, replacing it with hot water. 

The pump is installed at the water heater and controlled by a timer which can be set to family usage requirements. 

Hot water will also be instantly available at all other faucets located on the hot water supply line between the water heater and the faucet where the valve is installed.
