How an irrigation system is installed, step by step

A well-installed irrigation system should run for decades with seasonal service. Here's exactly what happens between your first estimate and your first automatic watering cycle.

Step by step

  1. 1

    Property assessment and water test

    Measure water pressure and flow at the supply; this decides how many heads each zone can run.

  2. 2

    Zone design

    Group areas by exposure and plant type: lawns on rotors or sprays, beds on drip.

  3. 3

    Utility locates

    Underground utilities are located and marked before any digging.

  4. 4

    Supply connection and backflow

    Tie into the water supply and install backflow prevention where required.

  5. 5

    Trenching and pipe

    Pull or trench pipe with minimal lawn disturbance; lines are laid to drain and blow out cleanly.

  6. 6

    Valves, heads and wiring

    Install the valve manifold, set heads at grade, and run low-voltage wire to the controller.

  7. 7

    Controller setup and coverage test

    Program the controller, run every zone, and adjust arcs and nozzles for head-to-head coverage.

How long does it take?

Most residential installs are completed in one to two days depending on zone count and hardscape crossings. Lawn trenches settle within a few weeks.

What makes installs last

  • Correct zone sizing for your actual pressure and flow
  • Serviceable fittings (we use Blu-Lock) rather than buried glue joints
  • Valve boxes you can find and open
  • Head-to-head coverage so there are no dry corners

Common questions

Will installation wreck my lawn?
Trenches are narrow and the sod is replaced; most lines disappear within a few weeks of watering.
What does a system cost?
A single zone starts at $499 and two zones at $699; the instant estimator prices larger systems.
Do I need to be home?
