Review: Every house should have one of these - This thing is revolutionary when it comes to hooking yo water lines. It was easy to install and hook up to, and it saves a load of trouble and headaches when new lines need added or old ones need fixed. The ability to shut off one targeted spot in the house and leave water flowing to the rest of the house is incredible.
