Irrigation pipe installation

Black roll pipe is somewhat more difficult to install, but not appreciably so. Black roll pipe is used in Northern areas because it will expand a small amount, which allows the water in it to be frozen with little or no damage — an important characteristic in the North.

In the South we typically will not have pipe freezing problems if we install the piping to the recommended 12 inch depth. Either black roll piping or PVC piping will work well in our climate, but you may find the PVC piping easier to install and repair.

Just imagine that your sprinkler system is installed and working nicely. Uncle Bob stops in to visit, and as he leaves he backs into the yard — right over a sprinkler. The sprinkler is crushed, of course, but since the sprinkler was screwed directly into the PVC pipe, a good portion of the pipe below ground is broken, too.

Swing pipe is installed between the PVC piping and the sprinkler to allow some flexibility if the sprinkler is crushed or driven over. Usually two feet of swing pipe will be used to attach a sprinkler to the PVC, but three or four feet may be used if needed. Specialists In Flood Irrigation.

Our Core Values. Proper installation requires planning and care, but pays off in efficiency and consistent water pressure.

Mark the path of your pipes in your yard using spray paint. Check the plan for your irrigation system, making corrections to reduce the number of bends and turns in the pipe because each bend will reduce water pressure slightly. Dig a trench approximately 6 to 12 inches deep along your marked lines using a trenching shovel or mechanical trencher. Although they're more work, deeper trenches provide better protection against freezing or other pipe damage.

Dig trenches for your main irrigation lines first, then come back and dig the trenches for branches off the main lines. Check the grade of your trenches, digging portions of them out with a trenching shovel to create a level trench bottom. If the trenches aren't level, you may lose water pressure within your pipes.

This is an example of large pipe being installed at the same time as a wire. The larger the pipe, the more the soil is displaced. This will settle or it can be compacted after installation. As you can see, healthy grass results in very little damage to the grass. This is a closeup view of the pipe being pulled into the ground.
