Not really quite sure what the problem is...My sprinkler system is on a timer and just this morning they would not turn off. I shut the timer to the off position and it was still running and then I unplugged the timer unit the water was still running... Finally I went to the front of the house and shut off the main valve and the water finally turned off...I have no clue about sprinkler system and am hoping someone might be able to shed some light. Thanks in advance for the assistance!
