Oh man i remeber having same problem with my habbit of playing with equipment ! LOL.
I dont remember now but i can send you a full picture so you can zoom in on it .picture of how it is suppose to be connected, Two blue lines conected on top of this square valve if you looking at it from its back. And there are numbers 1 "IN" and 3 "OUT" on top.
Also it will have two screws on top.
Try reversing the membraine inside the i think its called "Hydraulyc Automatic shut off valve "
