replacement of irrigation values

I need to replace 2 inch values and 3 3/4 inch values. My question may sound a little dumb, but how do I get the pipes out of the old values. I know that they unscrew out, but do I need to screw the pipes in the ground out of the ground first, then attach the values and then screw the pipes back into the ground. I guess I am asking what sequence do I need to follow to do the replacement. And what issues do I need to look out for when I do this?

Unless unions were used, when it comes to removing valves, it would seem that cutting pipe is required. After all, if the valve uses threaded connections and is installed in-line, if you try to turn the valve to loosen one threaded connection, you're going to be tightening the other. If the valves have been installed in just about any other configuration, there's no way to start unscrewing one of the two attachement points until the 1st attachement point is removed... and then you're back to the problem of if unions were not involved, you've got to cut a pipe somewhere.

The only other possible exception would be if a valve itself could be disassymboled to seperate the input side from the output side, but the few valves I've ever seen, the input/output are a part of a single body.

None of your zip files worked. I can see from the two pictures posted that there's no digging required. Simply cut them off and glue new valves on. All you'll need is two male adapters for the valves unless you plan on making them taller. Then you'll need a couple of couplings.

Thanks

All of this sounds like I need to have a professional come in and do it for me, but thanks for the help.

Why replace the valves, if the old ones can be repaired?

Cost

Just a final question, what should it cost to replace all five valves and check out the system? I got a quote for $475.00 from a licensed contractor. I live in So California if that makes a difference. Thanks.
