Issues with Main Valve and Zones not turning on

Sorry it’s taking me so long to update you guys.

So it turns out valve #6 was the main pump for whatever reason. I had valve M (labled on my sketch) and valve #6 backwards on the controller.

It was a very simple fix, but I had to have someone bring out a toner to determine the cross up.

Everything is working fine now. Thanks for all the help.

Cheers
