Warning, thread high jack warning, speaking of Homer Simpson moves, no disrespect here Fryedaddy but good stuff for Memorial weekend!
Been meaning to confess this one for some time now, turned on my sprinkler system last spring and was walking around the yard manually turning on zones with a remote to make sure all heads were working correctly when I came to zone 6, it would not turn on. Checked the wiring to the valve, cleaned the valve, replaced the valve, dealt with water in the valve hole, you name it no go. Oh wait, I was at zone 7, zone 6 was on the other side of the house and working just fine. D"oh!
