Begin installing a recirculation pump by turning off the water supply at the main valve. Locate a bathroom fixture such as a shower, toilet or sink that is at the farthest distance from the water heater, and turn off its cold and hot water supply valves. Disconnect the hot water supply line of the heater.
Install the recirculation pump closer to the hot portion of the heater, while ensuring that its timer is easy to access. Connect the heater's hot water line to the pump. Use steel or copper pipes or tubing to connect the pump to lines of the fixture selected using a washer. Tighten the connections with a wrench.
After installing the control box, adjust the timer so that the pump fuctions during the morning hours. Finally, switch on the water supply at the main valve and at the hot and cold valves of the fixture. Test the pump to ensure it works.
Before installing a recirculation pump, check the plumbing codes in your area. Generally, municipal offices require that an individual have a plumber's license to carry out such an installation.Learn more about Home Maintenance
