    I believe in areas where the ground does not freeze, 2 feet is the depth used. For areas where the ground does freeze, you must have your piping at least 4 feet deep. Anything less, can allow them to burst when the water in the pipe freezes and is turned on prior to the pipe water thawing completely.

    Assume Las means Las Vegas. Any below ground water line should be below the frost level in your area. I don't know what that is. Up here is eastern WA, we always blow out our irrigation lines with compressed air in late October - after growing season is done and irrigation canals are shut down. Be sure to go deep enough to prevent accidental damage when planting in the area where the line is buried.

    You may want to use pex if you are concerned about frost. Not sure where you are located so it may not be an issue. We converted all plumbing to pex and haven't had any burst pipes in 3 years at our farmhouse. Love that stuff, it expands when frozen.
