Question
I have started having a problem with my sprinklers not staying on when the program is running, they pop up and start to spray but shut off and it is the same with alol three of my stations.  I checked and completely reprogramed the timer and it did not change.

Answer
It sounds to me like there is a problem with the electrical current sent to the valves from the controller.  If you know how to use a multimeter you can check the voltage output from the controller both at the valves (you will need to remove the wire connectors), and the output at the controller.  There should be 24 volts output continuous output when the station is on.  If you dont want to do this, a sprinkler repair person should be able to check it for you.  If there is a problem with the voltage, you may need to replace the controller.
