I need a timer that can be set to turn on twice a week for about an hour, that plugs into 120 standard outlet and basically waters a patch of sod automatically. The homeower is older and doesn't want to be responsible for the irrigation. I need something I can sell them that is easy to install and setup. It needs to run water to a hose end sprinkler. Searched ebay and didn't see anything. I can get the job if I can irrigate automatically w/o construction.
