How to install a dedicated hot water recirc line?
Join the two 1/2″ lines to a single 3/4″ line back to your cold water input to the water heater. Install a circulating pump with a built in check valve in the line to prevent reverse flow. Put the pump on a timer, motion detector or both to suit your families needs. Never have to wait for hot water again.
Is it safe to install a recirculating hot water system?

Where does the return loop go in a recirculating hot water system?
The first part of the loop begins at the water heater and goes to the sources of hot water in your home. A return loop is needed in a recirculating hot water system. So, the piping must be run in the opposite direction. If you don’t install a loop, the hot water cannot move continuously throughout the system.

These valves can be installed after the loop is completed. You can install this valve in the vertical – or horizontal – loop pipe just before it enters the water heater. The valve should be within 5 feet of the water heater and it needs a 1/8-inch hole drilled in the flapper of the valve.
