We discovered yesterday afternoon that the station that waters the blue tee on hole # 12 is not working. The computer shows that it is receiving the signal and returning it back to the computer, which means it is an electrical problem somewhere between the controller and the valve that turns the station on. (Probably a broken wire). These can be difficult to find and very time consuming. I'm just glad that my irrigator spotted it fairly quickly before it became a real problem. We are able to water it manually while we try to find and fix the problem.
