how to add sprinkler head to existing system

Adding a sprinkler head to your existing irrigation system might seem daunting, but with the right tools and a little know-how, it's a manageable DIY project. This guide will walk you through the process, helping you get that extra coverage you need for a lush, healthy lawn.

Assessing Your Needs

Before you even grab your tools, take some time to plan. This will save you time, effort, and potential headaches down the line.

1. Identify the Water Source

Locate your main water valve and the nearest sprinkler zone. Adding a new head is easiest when connecting to an existing zone, avoiding the need to run new pipes. If you need more zones, you may need to install a new valve. This is a more involved task that usually requires professional help.

2. Determine Sprinkler Head Type and Placement

Consider the type of sprinkler head best suited to the area you want to water. Rotary heads offer wide coverage, while spray heads provide a more focused spray. The optimal placement depends on the size and shape of your lawn. A poorly placed head can lead to uneven watering.

3. Gather Your Materials

You'll need these materials:

Sprinkler head: Choose a head compatible with your system's pressure.
PVC pipe: The diameter should match your existing system.
PVC fittings: Elbows, tees, and couplings as needed to connect the new head. Use high-quality fittings for a secure and leak-free connection.
PVC cement: Use a PVC cement specifically designed for your pipe size.
Pipe cutter or hacksaw: To cut the PVC pipe to the correct length.
Measuring tape: For accurate measurements.
Shovel or post hole digger: To dig trenches for new pipe if needed.
Safety Glasses & Gloves: Always protect your eyes and hands.

Step-by-Step Installation

Once you have your materials, follow these steps:

1. Turn Off the Water

This is crucial to prevent leaks and potential water damage. Locate your main water valve and turn it off completely.

2. Locate Connection Point

Decide on the best location to connect the new head to your existing system. Ideally, you'll tap into an existing pipe near the desired location.

3. Cut and Prepare the Pipe

Carefully cut the pipe using your pipe cutter or hacksaw, ensuring a clean, square cut. This is important for a tight fitting.

4. Install Fittings

Using PVC cement, connect the necessary fittings to create the pathway for the new head. Ensure a proper fitting. Allow the cement to cure fully according to the manufacturer's instructions.

5. Install the Sprinkler Head

Once the fittings are secure and the cement has cured, attach the new sprinkler head.

6. Bury the Pipe (if necessary)

If you had to run new pipe, bury it carefully, ensuring it's deep enough to be protected from damage. Backfill the trench.

7. Turn on the Water and Test

Slowly turn the main water valve back on. Carefully inspect all connections for leaks. Adjust the sprinkler head as needed to achieve optimal coverage.

Troubleshooting Tips

Leaks: Check all connections for tightness. If a leak persists, you may need to replace the fittings or the pipe.
Low Water Pressure: This could indicate a problem with your main water supply or a clogged sprinkler head.
Uneven Watering: Adjust the sprinkler head to achieve uniform coverage.

Adding a sprinkler head is a straightforward process that can significantly improve your lawn's health. Remember to plan carefully, gather the right materials, and follow these steps for a successful installation. If you're unsure about any part of the process, it's always best to consult a professional.
