Because of the time of the year I won't be installing this until winter. It will replace a Watts Backflow preventer that leaks. My neighbors have the Wilkins 3/4" like this and they work great.
I bought the valve for someone else who doesn't do much computer work. He needed it for a customer's job. A new one from other places would have been over $500, this one was almost 1/3 of that. Great deal.
