Rated 4 out of 5 by This was a great replacement I was satisfied with the product, but one thing that bothered me was after installation I turned on the water pressure and saw that water was purging out of the center valve. I saw that there was a screw on the side of the valve (the one with water purging) and turned it halfway with a screwdriver. After turning on the water pressure I saw that there was no more water shooting out...case closed!! April 25, 2012
