Installed one of these, wife absolutely loves it. Suggestion for those wanting to install, buy the sensor kit first (~$50) and install on farthest sink, before buying pump kit. The valve itself seems to work pretty well without a pump necessary. I believe simple thermodynamics is enough to cause the water to circulate well enough in this system. I run the pump a few hours in the morning, but the hot water is fairly quick 24/7 ,even without pump operating. Worst case, is you end up buying the pump and have an extra sensor. Think many homes may benefit with two sensors anyway.
