| I have some zones that are losing pressure. I find that when the timer opens them, the sprinklers will not pop all the way, but they will if I open the bleed screw.
I've found a couple sections of wire where the insulation has been stripped and there is some exposed wire that is corroded. Can this cause a reduction in the voltage getting to the solenoid? Can reduced power to the solenoid cause a reduction in pressure, or is a valve fully open or fully closed with nothing between? I've solved this problem before by simply replacing the valve, but this is a good brass one, and I would rather try to fix the actual problem if possible. |

| The first thing I would do is repair the wires then check if the valve has a flow control knob. If it does then make sure it is open all the way. If that does not fix the problem the solinoid needs to be replaced. |
