solenoid

I didn't see this issue on any other posts, so........ when I turn a solenoid "on" 1/4 turn, nothing happens, not for any of the four of them. 1/2 turn or 3/4 turn, still no water comes out of the sprinkler heads. How can this be? It's supposed to manually turn the water on. I know the water...

Solenoid valve used in outside.When lightning strikes, thunderstorm coming, it will have a bad damage on irrigation systems. Years ago, electro-mechanical controllers and hydraulic systems were somewhat immune to lightning or electrical surges. With the advent of solid-state control products and...
