I have exactly the same valve, I think. Went to local Ewing's here in Chandler, AZ and they sold me two R1359s. I was having trouble with the valve turning on (solenoids are OK). After replacing the diaphragm, everything worked OK for a while, but then I noticed the sprinklers were weeping, so I cranked off the screws and checked for debris, etc. All looked good but after re-assembling the weeping was worse. I swapped out the new diaphagm with the one that had never been used, and the sprinklers...
