Adding 1/2 Inch Drip Supply Lines: A Step-by-Step Guide

Introduction

This comprehensive guide demonstrates my preferred method for adding 1/2" drip supply lines. My approach minimizes the risk of damage from foot traffic in the area, ensuring a long-lasting and efficient irrigation system.

Required Parts

For this installation, you'll need the following recommended parts:

1. 1/2" Funny Elbow (connects to swing pipe, reducing damage risk)
2. 1/2" Threaded Coupler
3. 1/2" Barbed Male Adapter
4. 1/2" Tubing
5. 1/2" Barbed Ball Valves

Tubing Color Variations

Note that the 1/2" tubing shown here is black, but it functions identically to the brown tubing featured in other images. The color difference does not affect performance or installation methods.

Assembly Step 1: Connecting Fittings

Begin by threading the coupling onto the funny elbow and barbed adapter. For a secure and leak-proof fit, I recommend using Teflon tape on these threaded connections.

Tubing Installation

Next, attach the 1/2" tubing to the assembled fittings. While the length can vary from a few inches to over 100 feet, we recommend keeping individual sections under 30 feet for easier management and maintenance. Remember, this tubing has a maximum flow rate of approximately 4 gallons per minute (240 gallons per hour). Exceeding this rate will result in poor system performance.

Adding a Ball Valve

To insert a barbed ball valve, simply cut the line at the desired location and press the valve into place. This step allows for greater control over your irrigation system.

Ball Valve Usage and Benefits

While not strictly necessary, I prefer using barbed ball valves on installations. They allow you to shut off water to specific sections when not in use, providing greater control and efficiency in your irrigation system.

Typical Installation Length

This image shows a short example for demonstration purposes. In most real-world applications, the tubing will run the full length of a garden or flower bed, providing water to multiple plants or zones.

Application Examples

These images demonstrate various ways to utilize this 1/2 inch supply line in your irrigation setup, showcasing its versatility in different garden layouts and plant types.

Micro Spray Application

This example shows a micro spray emitter, which can be easily connected to your 1/2 inch drip supply line for targeted watering of larger areas or groups of plants.

Bubbler Application

A bubbler can be attached to your 1/2 inch drip supply line for localized, high-volume watering of larger plants or trees, ensuring deep root hydration.

Drip Tubing Example

This image demonstrates how smaller 1/4 inch drip tubing can be connected to your 1/2 inch supply line, allowing for precise water delivery to multiple plants in a row or in a specific pattern.
