    First off I don't do much in the way of irrigation unless I need to fix a line I hit when doing grade and seed work, and the sprinkler contractor I work with is out of town for a few weeks.

    I have a job that I am bringing dirt in and going to fill in some low areas in the yard that have sunk pretty good (6"+), and the Control valve was already low. What is the best way to raise it? Needs to come up 6" to 8" and I was thinking a riser like is used by water dept, but no luck finding one. The dimensions are 9 1/4" wide and 2" deep. It is from Carson Industries and it says Irrigation Control Valve on the top of the lid, but probably from 30 years ago when my local contractor put it in. Any ideas or suggestions would be great.

    Photos would help. If you have a Carson valve box, it can be raised with 6-inch extensions.

    I think Carson also made boxes for curb stop valves, and that could be a different animal, if the OP is thinking water service valves.

    I was just thinking that the solution was a riser like you use on a curb stop, but it is and actual irrigation valve box circular style. I forgot to grab a picture while I was there(one of my things I am working on for 2012 is pictures). I might try and grab one tomorrow when it is light out. Thanks for your help, gives me a route to go and start.

    For round boxes you can also use a piece of NDS drain pipe vertically to extend the box and cut it to whatever height you need. 8" dia. pipe works well with a dura box of the same size but I'm not sure about other manufacturers. The down side is you have to dig up and remove the exisiting box to put the pipe under it. An extension would be easier. Just another option.

    The small round boxes will fit atop drain pipe, but you might lose repair access if you extend those.

    Easier to remove the box completely and just bury whatever is inside it.

    Some installers never use boxes for valves. Go figure.
