If you're ready to upgrade from a manual watering system, this step-by-step guide on how to install a lawn irrigation system the right way is for you.

Why Does Your Lawn Need an Irrigation System?

• Ensures even water distribution
• Reduces water waste
• Saves time and effort
• Keeps the grass and plants healthy
• Increases property value

Tools and Materials You'll Need

• PVC pipes or polyethylene tubing
• Sprinkler heads
• Trenching shovel or trenching machine
• Control valves
• Pipe cutter
• Irrigation timer/controller
• Backflow preventer
• Teflon tape
• Connectors and fittings

Step-by-Step Guide to Install Lawn Irrigation System

Step 1: Plan Your Irrigation Layout

Start by measuring your lawn and drawing a simple layout.

Mark:

• Lawn size and shape
• Water source location
• Plant beds and grass areas
• Slopes or uneven surfaces

Step 2: Check Water Pressure and Flow

Test your water pressure and flow before purchasing sprinkler heads. Most systems require:

• Water pressure between 30–50 PSI
• Adequate gallons per minute (GPM)

This ensures your sprinklers work efficiently without weak spray or pressure loss.

Step 3: Mark and Dig Trenches

Use spray paint or string to mark where the pipes will run.

• Dig trenches 6-12 inches deep
• Keep trenches straight for easier pipe installation
• Avoid damaging existing utility lines

Rent a trenching machine to save time for your larger lawns.

Step 4: Install the Main Line and Valves

Connect the main irrigation setup line to your home's water supply.

Install:

• Backflow preventer (required by many local codes)
• Control valves for each zone
• Valve box to protect components

Use Teflon tape to wrap the threaded connections to prevent leaks.

Step 5: Lay the Pipes and Install Sprinkler Heads

Lay PVC pipes or tubing inside the trenches. Connect the sprinkler heads at planned intervals.

Consider these tips:

• Keep sprinkler heads level with the ground
• Space them evenly for full coverage
• Use the correct sprinkler type (rotor for large areas and spray heads for small lawns)

Step 6: Install the Controller

Mount the irrigation controller in a sheltered location, such as a garage wall.

• Connect wires from valves to the controller
• Program water schedule
• Set zone timing based on plant needs

Modern smart controllers adjust watering times depending on rainfall and temperature.

Step 7: Test the System

Before covering the trenches:

• Turn on the water supply
• Adjust sprinkler direction and spray pattern
• Ensure proper water pressure
• Check for leaks

Fix all the issues before burying the pipes.

Step 8: Cover Trenches and Final Adjustments

Once everything works perfectly:

• Carefully refill trenches
• Press soil firmly
• Replace sod if needed

Run the system to ensure nothing shifted during backfilling.
