I have a sprinkler system with three zones, I just replaced the valve for Zone1 as it had cracked, and all three zones worked for about a week and now when the controller reaches zone3 the heads don't pop up and it sounds like the water backs up (the copper pipe leading from the house into the ground shakes quite violently and can no longer hear running water). I am wondering if this might be most likely caused by a clog in the sprinkler lines or a problem with the Zone3 valve or something else. I have opened up the heads on the Zone3 sprinklers and they are dry. Thank you for any suggestions you might have.

I replaced a valve this Spring on a zone, and had similar situation. I went back and the local guy gave me another valve...fixed it. YMMV.
Maybe a bad/stiff diaphragm.

I think if there were debris in the lines downstream from the zone3 valve, at least some of the heads would get some water and work.
My guess would be that some debris got > I have a sprinkler system with three zones, I just replaced the valve
