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.
Most sprinkler professionals recommend burying sprinkler lines 8 to 12 inches deep in the ground. Sprinkler lines should be buried at least the depth of the pipe, which is 4 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.
What Size PVC Pipe is Used For Irrigation? One of the most commonly used sizes of PVC pipe for irrigation systems are 13mm, 19mm, and 25mm. For irrigation laterals, PVC pipes that are at least ¾” thick (19.05mm) are preferred since those that are ½” thick (12.7mm) clog much faster and often.
The first factor in determining how deep to bury your sprinkler lines is the size of the pipe bringing water from the main to the individual heads. Depending on available water pressure, these sprinkler supply lines are typically three-quarters to one inch in diameter.
The most common pipe diameter for water mains is 6 to 16 inches, with 8, 10, and 12 inches also being used. Branch lines providing service to individual homes, offices, buildings, and businesses vary in size from as small as half an inch in diameter up to 6 inches.
Pipe slope is a critical element in reducing water collection following a sprinkler system drain. Water removal is important in that the largest detriment to sprinkler system life, corrosion, occurs across interfaces between air and water.
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.
Without digging, it is possible to find sprinkler lines by getting a design map from the company that installed the system. If this is not possible, one could go to the valve box and follow a line back to each of the head sprinklers in a circuit. Or one could utilize an electronic water-detection device.
Other secondary private utility lines can include site lighting, storm sewer lines, irrigation lines, underground storage tanks (USTs) and vent pipes. The 811 One Call system will generally not mark secondary utilities and will not provide the depths of any utilities as part of their locate.
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.

The standard depth for water lines in the U.S. is around 36 inches, but this can vary from location to location.
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".
Broken sprinkler pipe
The average cost of repairing broken pipes is $150 – $370, where the actual price depends on the type of pipe, the cost of labor, and how long it takes to complete the repair: PVC pipes typically cost $1.30 – $3.90 per linear foot. Polyethylene pipes usually cost $0.45 – $1.30 per linear foot.
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.
Wet pipe sprinkler systems are the most common. In this system the sprinkler piping is constantly filled with water.
Class 200 pipe, the most common class pipe used in irrigation, is rated for 200 pounds per square inch pressure (psi) and has a wall thickness of . 063” for a 1” pipe.
6 Deflector Position (Standard Pendent and Upright Spray Sprinklers) Under unobstructed construction, the distance between the sprinkler deflector and the ceiling shall be a minimum of 1 in. (25 mm) and a maximum of 12 in. (300 mm) throughout the area of coverage of the sprinkler.
Yes, PEX pipes can be buried underground. However, it's important to follow local building codes and guidelines to ensure compliance and the longevity of your plumbing system. To ensure optimal performance and protection against external factors, it is essential to bury insulated PEX pipe at the appropriate depth.

So, if a pipe gets narrower (A, the area, decreases), the velocity of water has to increase to compensate for the change. You can experience this increase in fluid velocity as a corresponding increase in dynamic pressure.
