All of the sprinkler heads on one of my zones are pulsating. It is as if something is turning the water flow from high to low. Is this a bad zone control vale or solenoid or ????????
Thanks for your help
It could be that the valves are busted, there is air getting in the line, something in your house keeps drawing water, the heads are busted, etc. It could be a lot of things. Do you have more details?
