Ok thanks for the help. I think this will be the way to go then.
Hi, I am wanting to install a sprinkler timer to my existing system. I am thinking that its as easy as removing the valve I use to it on now (As seen in the picture below) and replacing it with the timer found at: [url]http://www.sprinklerwarehouse.com/710-011-DIG-DC-Single-Station-Controller-p/710-011.htm[/url] Is this correct? Also how long does a 9v battery usually last in a controller like that? Thank you, Aubrey
