A week ago i started my watering system and it worked fine. but yesterday i turned it on and i did not have the usual water pressure and i went to the valve box that is below ground and when i opend it it looked like water had gone in and some dirt had washed into the wires and the valves and while looking the dirt looked back like something had burnt or the wires , so i turned the bonnet screw that is on top and it did not make a difference as the water presseure was the same , so i am not sure...
