Rated 5 out of 5 by from Valve works fine Had to replace my old valve with this unit. My sprinkler system works fine using this valve. When installing the valve use union joints on each side of the valve. It will be a lot easier to replace the valve in the future should the need arise.

Rated 1 out of 5 by from Top Blows Off within 30 days In my opinion this product does not hold up. I had water shooting up when I was out of town less than month after install. Luckily neighbor saw and shut off my water. I ended up spending more money on a brass product that costs roughly ten times this product. I am out the install money from my handiman. I had a plumber install the other product.
