more likely a bad batch of valves
Rainbird DV valves
rural water system
Found a small split in the diaphram, [hard to see] Took apart valve 13 and that diaphram had a split too.[exactly same as previous] Question--blowing out the system for the winter with too much pressure cause this ? Age of system is 4 years and 8 out of 13 diaphrams bad at one time.
city water or well water?
Rainbird DV valves
Bought a new valve repair kit and put in new diaphram in valve 1 and it works now.
It seems odd to have this many diaphrams bad in one year. Anyone have a sectional view of the DV valve ?
What fails in them or do they dry out?
Turned on this spring-ZONES 4,6,10,11,12 worked by controller no work on ZONES 1,2,3,5,7,8,9,13.
There could be a blockage in the body of a valve - one way this is evident, is if a valve will operate by way of the bleed screw, but not by way of the solenoid.

Refer to original message---Took valves apart and everything looks good
now you open up a faulty valve and have a look-see

Swapping bad zone 1 solenoid with good zone 4 results---Zone 1 operated by zone 4 solenoid still bad. Zone 4 operated by zone 1 solenoid works. Not a solenoid problem,
Swap solenoids between good and bad zones, and report back.
