Adding a Zone to an Existing Sprinkler System: The Complete Guide

Are you facing the challenge of having a wooded area in your garden that is not adequately watered by your current sprinkler system? Don't worry! In this comprehensive guide, we will walk you through the process of adding a zone to your existing system to ensure that your newly planted seeds receive sufficient water. Additionally, we will cover the fundamentals of irrigation, including understanding mainline and zone line connections, valve and diaphragm functioning, and wiring the system. So, let's get started and transform your irrigation system into a well-watered paradise!

1. Introduction

Maintaining a lush and healthy garden requires a reliable and efficient sprinkler system. However, there are often areas that are overlooked or not adequately watered, such as wooded areas. This can result in parched plants and unsuccessful growth. To address this issue, adding a zone specifically for the wooded area is essential. In this guide, we will show you how to modify your existing system to accommodate this zone and ensure that your plants receive the water they need.

2. The Issue with the Existing Sprinkler System

Before diving into the solution, let's understand the issue with the existing system. The client, in this case, had a wooded area in their garden that was not being watered by their current sprinkler system. This led to the growth of unhealthy plants and an unsightly garden. Recognizing the problem, the client reached out for assistance in adding a separate zone to water the wooded area adequately.

3. The Solution: Adding a Zone to the Wooded Area

To address the issue at hand, the solution was to add a new zone to the sprinkler system dedicated solely to the wooded area. By doing so, the newly planted seeds in that area would receive the necessary amount of water for healthy growth. The following sections will guide you through the steps involved in adding the zone to your existing system.

4. Understanding the Basics of Irrigation

Before proceeding with the modification of your sprinkler system, it is crucial to have a basic understanding of irrigation. This knowledge will help you make informed decisions and ensure that the added zone functions effectively. Let's explore the fundamental concepts of irrigation:

Mainline and Zone Line

In an irrigation system, the mainline is a pipe that runs around the garden, supplying water to various zones. The mainline follows a clockwise direction, maintaining a continuous flow of water. Each zone is connected to the mainline via a valve, which controls the water flow to that specific area. The section beyond the valve, known as the zone line or lateral, delivers water to the sprinkler heads in that zone.

Valve and Diaphragm Function

The valve is a crucial component of the sprinkler system. It acts as a gateway, regulating the flow of water to the zones. When the clock sends a signal, the valve opens up, allowing water to pass through the diaphragm and reach the sprinkler heads. It is essential to understand the valve's components, such as the solenoid and diaphragm, for proper installation and functioning.

Wiring the System

The irrigation system requires appropriate wiring for seamless operation. Understanding the wiring connections can help you efficiently modify your system. The common wire connects to all the valves, while each color wire represents an individual zone. Programmable sprinkler clocks make it user-friendly to set up and control the watering schedule.

5. Recommended Setup for Winter Months

To ensure optimal functioning and prevent freezing during winter months, it is essential to have a proper setup. While a standard ball valve in the basement or crawlspace can be used to shut off the water, an alternate recommendation is to use a tee with a threaded plug or cap. This setup allows any residual water to drain out, preventing system damage or freezing.

6. Modifying the Existing System

Now that you have a grasp of the irrigation basics, it's time to modify your existing system and add the zone for the wooded area. This section will guide you through the necessary steps and ensure a successful integration.

Installing Additional Zones

Adding more zones to your sprinkler system requires the incorporation of extra wires and connections. By following the appropriate procedures, you can seamlessly expand your system to cater to the specific needs of your garden. We will cover the process of installing the necessary equipment and properly connecting the wires.

Connecting Wires

Wiring plays a crucial role in the proper functioning of your sprinkler system. This subsection will walk you through the steps of connecting the wires to the valves and ensuring the correct setup for smooth operation. We will explain how to link the common wire and the zone line, simplifying the connection process.

7. Installing the Sprinkler Heads

The sprinkler heads are responsible for distributing water to the desired areas of your garden. Installing the right type of heads and adjusting their settings is crucial for optimal watering. This section will cover the installation process, including adjusting the arch, choosing the appropriate nozzles, and positioning the heads correctly.

Types of Heads: Rotor and Spray

There are different types of sprinkler heads available, such as rotor heads and spray heads. Each type serves a specific purpose, and choosing the right one depends on factors like water pressure and desired coverage. We will discuss the advantages and disadvantages of each type, enabling you to make an informed decision.

Adjusting the Arch and Direction

Properly adjusting the arch and direction of the sprinkler heads is essential for achieving the desired watering coverage. We will guide you through the process of fine-tuning the settings to ensure that water is distributed evenly across your garden.

Choosing the Correct Nozzle

The choice of nozzle greatly influences the water output of your sprinkler heads. By selecting the correct nozzle size based on your water pressure and desired flow rate, you can optimize the efficiency of your system. We will provide guidance on how to determine the appropriate nozzle size for your specific requirements.

8. Connecting the Pipe and Funny Pipe

Connecting the pipes in an irrigation system requires careful consideration. This section will cover the steps involved in connecting the mainline and lateral pipes, ensuring a secure and reliable connection. Additionally, we will introduce the concept of funny pipe, a flexible and convenient option for connecting the sprinkler heads.

9. Stabilizing the Sprinkler Heads

To maintain consistent and accurate water distribution, it is essential to stabilize the sprinkler heads. This subsection will explain the importance of proper stabilization and guide you through the process of using pipe cutters to secure the heads in place. Preventing movement and angular deviations ensures optimal water coverage.

10. Conclusion

With the completion of the modifications and installation, you can now enjoy a well-watered garden, including those previously neglected wooded areas. By following the steps outlined in this guide and understanding the basics of irrigation, you have empowered yourself to enhance the efficiency and effectiveness of your sprinkler system. So, grab your tools and get started on transforming your garden into a flourishing oasis!
