I have an older automated sprinkler valve that does not completely shut off even when tightening the flow control all the way.It's an older brass model with Lawnlife imprinted on the top. I'm not certain how old or what maintenance has been performed on it.When I remove the bonnet, I don't see a spring. And, I can't lift up the diaphragm...it appears to have a nut on top holding it down with a spring underneath...or at least something pulling it back down. It slides up and down on a shaft.Any suggested fixes or links to more details on this valve system are appreciated. via /r/DIY http://ift.tt/2qQohPb
