Well, while I'm trying to repair/fix my valve leaking problem, I thought I'd ask how a solenoid valve drop the pressure on one side of the diaphram valve so that the diaphram opens to let flow to the sprinklers. I am assuming that there is more pressure on the top of the diaphram when shut, thus shut. So, does the soleniod (retracting type) drop that pressure somehow?
