The easiest and most cost effective way of repairing this is to purchase an identical valve (same make, model, etc...) Then disassemble the problem valve and replace the bonnet, diaphragm, and solenoid from the new valve. Effectively rebuilding the old valve with all new parts. Good Luck!

Or go ahead and purchase a new valve of your choice.Dig a little deeper and replace the whole valve.This way when your done it will work and your all done.No springs in wrong or any thing else that may have went wrong or got lost when trying to dissasemble and reaemble in the pit.
Just a thought My experience your time and money ahead in many situations to go what may seem a longer route up front but ends up being a much shorter less frustrating route after all.

It isn't always easy to remove an old valve, and in the case of slip-connection valves, not even possible. If one valve can fail, the others might also fail. A little extra effort in the learning-about and repair of this one valve of five, might pay off in the future.
