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.
How deep do you trench for sprinklers?
Dig trenches following the string. Mark the sprinkler locations with flags or the stakes. Typical trench depths range from 6 to 12 inches. To run pipe under existing walkways you can “drill” using water pressure.
What size pipe should I use for sprinkler system?
For schedule 40 PVC, use 1/2-inch pipe for a 4 GPM system, 3/4-inch pipe for 8 GPMs, 1-inch pipe for 13 GPMs, 1 1/4-inch pipe for 22 GPMs, 1 1/2-inch pipe for 30 GPMs, and 2-inch pipe for 50 GPMs.

Does reducing pipe size increase pressure?
Because if the diameter of a pipe decreased, then the pressure in the pipeline will increase. As per Bernoulli’s theorem, pressure can be reduced when the area of conveyance is reduced. In the narrower pipe, the velocity can be high, and pressure can be higher.
Can PEX be used for lawn sprinklers?
One of the benefits of PEX is that it is easily adapted after it has been installed, creating a custom sprinkler design based on your lawn needs. You are able to modify existing sprinkler heads easily using the same techniques as when it was first installed.
How many sprinkler heads can you have on one line?
At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
How do I find a buried sprinkler line?
You can tell (roughly) where the pipes will be for that zone by finding the shortest path from the valve box that connects all the sprinklers in a zone. As long as you dig carefully, you shouldn’t have too much trouble. The pipes are usually pretty tough and are usually buried about a foot or so under the ground.
Where are PVC sprinkler lines?

What is Schedule 40 PVC pipe?
PVC Schedule 40 pipe is used for drainage and lower pressure water flow applications. Schedule 40 PVC pipe can handle up to 140 degrees F in temperature. PVC schedule 40 pipe is available in plain end or belled end that do not require coupling for installation. Pipe sizes range from ½” through 24” in diameter.
How long can a sprinkler line be?
LENGTH OF RUN LIMITS: ½ inch tubing can run up to 200 linear ft. ¼ inch tubing should not exceed 19 ft in length. MAXIMUM FLOW CAPACITY: ½ tubing can handle a maximum of 240 GPH or 4 GPM.
What is a trench digger?
What Is a Trencher? Trenchers are pieces of earthmoving equipment that use a metal chain with teeth made of high-strength steel to rip into the ground like a chainsaw would into a tree. Similar to an excavator, a trencher rips up the soil and any roots in the way to create a trench.
What tools do I need to dig a trench?
There are four types of hand tools used for trenching. They are the SharpShooter Shovel (or Drainage Spade), a couple different types of Trenching Shovels, the new Bottom Digger clean-out scoop, and the surprising Trenching Hoe (also called a Grub Hoe).
