My recommendation is to bury sprinkler lines 8-12 inches. I usually try to keep a standard depth of 10" because it provides more safety if I need to do some type of ground work so I don't have to worry about hitting lines. A walk-behind rototiller generally won't go deeper than 8".
Dig for Your Sprinkler System
The trenches will be relatively shallow, usually 6 to 12 inches deep, depending on your area's freeze cycles and frost severity. The trench must also be deep enough to allow the sprinklers to retract underground to prevent breakage from lawn machines.
Dig trenches following the string. Mark the sprinkler locations with flags or the stakes. Typical trench depths range from 6 to 12 inches.
Check for a System Map
While it might seem obvious, the easiest method for quickly locating sprinkler lines is to refer to a system map. Installation companies often prepare a detailed map that shows the exact location of sprinkler heads and service lines.
To make sure you avoid the sprinkler lines when digging, it's best to use a sprinkler valve locator, which may be available in your local hardware stores. Once the batteries are placed, turn on the power. Similar to an ordinary metal detector, also perform the test to assess if the equipment is functional.
The service is free. Call 811 before installing septic tanks and sewer lines, swimming pools, wells, sprinkler systems and water lines, basketball goal posts, mailbox posts, fence and deck posts, trees and shrubs. Even if you've had lines marked for previous projects, call 811 any time you plan to dig.
If only one of the irrigation valves is causing a water hammer, the easiest solution is to reduce the amount of water that the valve is using. That will reduce the velocity and the water hammer should stop. You then need to reduce the number of sprinkler heads the valve operates.
Sprinkler lines should be buried below the grass roots, and deep enough the sprinkler heads sit flush with the soil surface or slightly above grade. The depth varies depending on factors but typically ranges from eight to 12 inches.
You can also use underground wire cable locator NF-826 to find the underground sprinkler wires without digging and it's the easiest way. Let's dig a little deeper. Table of Contents: Part 1: What Is A Sprinkler Valve Box and A Sprinkler Valve.
Today, the best tool for the job is ground penetrating radar (GPR) as it accurately maps metal and PVC pipes. Traditional pipe locators use electricity and magnets to locate underground pipes.
Q: How Deep Do You Bury Sprinkler Wire? A: Like the pipes, you should bury the conduit at least 6 inches deep. Depending on your municipal code, you may be required to dig them deeper. This will protect it from shovels and tillers.
If trench is to be a joint trench (shared with other utilities) the following separations must be maintained: 24 inches between gas and electric lines. 12 inches between water and electric lines. 24 inches between sewer and electric lines.
Proper placement requires: • Head to head coverage: Each sprinkler should spray to the head beside and across it. Equal spacing between heads: Permits uniform water distribution. On narrow strips of grass use strip pattern spray heads and space them evenly apart.
International Plumbing Code states exterior water supply system piping should ideally lie 6 inches below the frost line and not less than 12 inches under grade for best performance.
The number of sprinkler heads per zone depends on the water pressure and flow rate of a system's water source. A traditional system may have a dozen rotors and 8 to 10 spray heads. An Irrigreen system only needs one sprinkler head per zone.

Check the Blueprint. Most irrigation systems have a map or layout showing the sprinkler heads' location. This blueprint is an invaluable tool for pinpointing the exact locations of the sprinkler heads, helping you avoid unnecessary digging.
If you do not reroute your irrigation system before laying down concrete, you can accidentally block your drip lines. Any blockage to your drip lines can cause the system to malfunction.
The depth of lines varies depending on type. Cable and phone lines are typically buried at one foot or less. Electrical lines and water lines are typically buried at around 2 feet or 24 inches underground. Things like high voltage electric lines and water pipes are buried at around 3 feet underground.
A buried sprinkler head can lead to flooding and a whole mess of other problems. When you suspect your sprinkler head is buried, you will want to dig it out immediately.
Ignoring water hammer can ultimately result in the catastrophic failure of your flow system. The long-term effects of water hammer can include: Pump and Flow System Damage.
