Thank you sooo much for the quick reply. The one that he installed was the Lowes and its all plastic and of course now that things have all gone south I remember seeing it saying something about 8 gpm or something like that. Doesn't look anything like what you have sent me (thanks again) but more like something like this.
But of course the one that I have doesnt have the higher ratings. I will check to make sure that he turned the water all the way back on - that could be it. I actually tried to get a sprinkler guy to come look at the problem but he told me that I needed to speak to a plumber. I live in California so I am not sure if I have any of those places around me but I can generally find anything on the internet. While I have you do you have any idea what would ahve caused the pressure to surge to the extent that it destroyed the valves? Could it have been a power surge? The sprinklers would make this weird sucking/thumping sound for hours (if I wasn't home to stop it) after they shut off - with all 3 zones squirting bits of water. The only way to stop it is to turn the water off at the main - but of course I get home hours after they shut off and the damage was done. Many Thanks for all the help!
