Almost everything about this little recirculation pump I like. Comes with a long cord, I think 8 feet, and has a clock face which allows turning on and off the pump in 15 minute intervals. I have mine installed above the hot water outlet of the water heater and plug the power cord into the same outlet that the washer and dryer are plugged into. Clock must be synchronized with actual time, then one can turn the pump on or off, depending on location of little tabs located around the face. These little tabs are somewhat awkward to work and appear to be easy to break. My pump has been working for about 3 plus years. By the way, mine is usually off at night, and is programmed on for 15 minutes every hour thru the day. I live in So. Cal. For some people, it could be left off thru much of the summer. I use thermostatically controlled devices which allows the water to flow in the cold water lines during cold times. They are separate, but very important for the system to work correctly.
