This is an old Champion 466 valve fitted with a solenoid conversion
kit. When
it comes on the water gushes out the anti-siphon part of the valve
rather than
going to the sprinkler.

The question is whether it's the anti-siphon valve that needs a repair
kit or the
diaphragm and seals in the actuator. Anyone here happen to know? Just
want
to have the right parts before shutting off the water.

TIA
