Irrigation Main Line Installation

Trenched irrigation mains, valve manifolds and sleeves for lawns, athletic fields and commercial landscapes that need water they can count on.

A good irrigation system starts with its mains. The pressurized line from the water source to the valve boxes is buried deep and expected to last, and a leak in it can turn into a sinkhole in a lawn. Doing the trenching and piping well lets the irrigation crew focus on heads and zones.

We trench and install irrigation mains, set valve manifold boxes at the right locations and place sleeves under driveways and walks before paving. The work coordinates with your irrigation designer and landscaper so the pipe goes where the plan needs it, and the trench is closed before the sod goes down.

Sleeves before paving

Installing sleeves under future driveways, walks and parking lots avoids cutting new concrete later. We set and mark them so the irrigation crew can find the ends.

Depth and pressure

Mains carry full line pressure. Joints, restraint and depth follow the design so lines survive frost and traffic.

Working with other trades

Landscape and irrigation schedules overlap. We coordinate so the trench is open when needed and closed and compacted before sod, seed or beds are installed.

Winterizing mains

Irrigation mains need to be drained or blown out where freezing is possible, and valve boxes need accessible drains. We plan the system with a low point and a drain so winter does not damage it.

Questions

Irrigation Main Lines FAQ

Do you install sprinkler heads?

We focus on the underground mains, sleeves and manifolds. Heads and controllers are usually installed by the irrigation contractor, and we coordinate with them.

Can you bore under my driveway instead of cutting it?

Often. Boring or sleeves placed in advance protect the surface and save restoration work.

How deep is an irrigation main?

Depth depends on pressure, frost and traffic. We build to the design and local practice.

Can you add a main to an existing system?

Yes. We tie into the existing line with the right fittings and restore the lawn afterward.

Do irrigation mains need winterizing?

In many areas, yes. Systems are drained or blown out before hard freezes, and good design makes that easy.
