Occasionally retic does weird stuff.
The good news is that being a ‘closed system’ there are only so many variables that can go wrong. If you have an analytical mind then you can solve most problems by a process of deduction.
Yesterday I went to see a client whose retic had come on and wouldn’t go off. They had been on holidays when this happened so they came home to huge water bill.
The logical answer is that both the master valve and the station valve had failed and stuck open simultaneously allowing water thru. But what are the chances of that? I’d be guessing one in a million so I started by testing the control box to see if there were any issues there.
By turning the valves on and off manually I was able to detect that all 3 of the clients solenoids were faulty. The fault was intermitent, but it was there. The end result was 3 new solenoids and no more problems.
