Question
The sprinkler system (aka irrigation system) would go on randomly and goes through the entire cycle.  I replaced the clock and the same thing is happening.  Any suggestions?

Answer
Hey Perry, I hope this helps. The only thing I would suggest, is check your clock and make sure you have it programmed correctly. Most controllers have multiple programs and multiple start times that can be programmed into it. Go through each program and check each valve run time, start time, day to run time, and make sure only one program is programmed in. Otherwise you might have a ghost and you might have to call the ghostbusters(ha, ha). Good luck and have a great day.
