Rated 4.7 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by It was a great price I looked at other places but this was the best price. I had to take it apart because I wanted to go in the other direction. All I had to do was switch the valves and place them in the other direction. May 20, 2014
Rated 4.0 out of 5.0 by Works as advertised Bought as a replacement for one which recently bursted in the casing due to a 24 degree freeze. It is interesting that although the brass casing bursted, the PVC pipes connected to it on both sides did not. At least we now know how to prepare it for freezing weather. March 25, 2014
Rated 5.0 out of 5.0 by Solid valve The 3/4" assembly is well constructed and relatively lightweight compared to the 1" version. July 17, 2013
