Product review (3 stars): Wastes water
The water throuh the system tastes great. The instructions for installation say that the unit will continue to allow a small stream of water through after shutting off.  This is supposed to last for a few seconds each time you use it for no more than the first 72 hours of use. Two weeks after installation and it's still doing it. We are on stage 3 water conservation here so this is very annoying.
