Valve won't come on
I have been working on this problem for 3 weekends- still no luck! I installed a master valve just behind the meter. Everythng seems to be working properly and I've even checked to voltage to the valve at around 25 volts, but it will not come on unless I slightly open the bleed valve- then it kicks on like it should. This is the 2nd brand new valve I've installed, but they both have the same problem. Anybody have any ideas?
