SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse Steps for How to Get Hot Water with a Recirculating Pump: 1. A recirculation line is a separate water pipe that runs off the hot-water line from the farthest plumbing fixture back to the water heater. 2. A pump at the water heater moves hot water through the recirculation line. Any cold water in the recirculation line is returned to the heater. 3. A check valve must be installed in the line to ensure hot water only goes in one direction. 4. An aqua-stat is mounted to the hot-water pipe. When it senses that hot water is returning to the heater, it shuts off the pump. 5. A timer is used to ensure that the system isn't maintaining the recirculation line when you're away at work or sleeping. 6. All-in-one pumps are available that have the aqua-stat and timer built into them. 7. Pumps and fittings can be used to push cold water in the hot-water pipe into the cold-water line until it senses that hot water has finally arrived from the heater.
