Richdel 711APR Sprinkler Valve Won't Turn Off

Richdel, 3/4", 711 APR sprinkler valve wouldn't turn 'off'
after station power was removed. Only way to turn off was to manually
close valve.


Without disconnecting (electrically) the solenoid valve, the top
was carefully removed with solenoid valve in-place. Noting diaphragm was
still in good shape, the solenoid was removed (held solenoid and unscrewed
cover assembly ( ref.
). Note: unscrewing assembly makes sure solenoid wired don't become pinched/disconnected.

Once solenoid was removed, a really small piece of dirt was
found between solenoid valve plunger and seat. Dirt was removed, plunger spring
was re-stretched (providing small amount of additional force on plunger seat
when plunger de-energized) and valve reassembled.

Voila'. Valve works great again - NO PARTS NEEDED. :thumbup:

Note: These sprinker valves are greater than 25y old.
Probably the most reliable thing in my house.

The key repair parts for a 711APR or 713APR will be found in the Irritrol 205TF valve still being today.
