Water supply line totally out of standard size and equipment supplied is the wrong size. The check valve is somewhere between 1/4 and 1/8. Maybe it's 3/16, but I won't be going to the hardware store for the fourth time to find out. To hook this up to my water line I now have a number of Frankenstein connections with a number of potential leak points. I'll take it apart, throw it in the trash and buy something new. Too bad I didn't try to install it closer to the time of purchase so I could return it. There would be too many zero stars. The product description must indicate the intended country for the product and must never be sold in the US market.
