PS: My old valve was stuck open. I was able to fix it by removing the valve and solenoid and striking the end of the stem down towards the valve lightly a couple of times with a hammer. (I've worked with this type of valve in my professional life before). My guess is dried up water deposits in the valve were keeping the valve from closing properly.
