All zones come on.

I started my sprinkler system for the summer. I turned the main valve on. All four zones came on at once but with very low water flow in most all heads. The fuse looks good. I shunted the fuse but the system still had all 4 zones going. I turned the main valve off and disconnected the transformer AC adapter, plugged the transformer back in and turned the main valve on again. All 4 zones still came on. What is wrong?

I'm not a proffesional, but!!

Did you check the bleed screws on your valves? Maybe when you (or a company) were winterizing the system. Make sure they are all "snuggly" tightened. Other than that suggestion, thats all I can think of. It would be kind of weird for all 4 valves to go bad at once.
I'm no expert..........YET! :D I just like to suggest things and learn... :thumbsup: See what the pro's have to say first.

Check the solenoid too. Make sure they are ' taught'
