Quoted from "mrfixit"

From what you've described you didn't cause the problem. Sometimes thing just break.
One time I was talking to a homeowner. I hadn't touched a thing yet. His mainline in the front lawn just burst. Was a fluke.

Is there a wire hooked up to the controller in the master valve or pump slot? mv or p
If so you have a master valve. If not you don't.

Are the flow controls turned off on the valves?

Maybe the shut off valve is broken in the off position.

Yeah, crazy things can happen for sure!

There is no wire connected to the MV terminal in the control box on my wall. So I am assuming there is no Master Valve.

I haven't changed anything on the valves and they all worked the morning before I changed out the 3 heads.

Try to be methodical - if a customer in a case like tells me the wiring is perfect, I check it anyway, measuring zone resistance at the controller

Figured out the problem.
The main valve on the back of the house is broken and stuck pretty much off. It does allow very little water through. Going to replace it and will be back in business.. Now the crazy part is how did this break by changing 3 sprinkler heads?!?!
