How to Install a Low-Flow Irrigation System

Installing a low flow, or drip irrigation system is a great way to save time and money during the growing season. Drip irrigation systems allow you to regulate a slow flow of water over time, keeping your lawn, garden or annuals adequately watered throughout the summer. Drip irrigation systems are fairly easy to install and use and can be modified to meet your changing water usage needs.

Difficulty: Moderate

Instructions

1. Compare the irrigation plan to your site and make changes as needed for actual conditions.

2. Begin at the water source and add a backflow preventer. This is usually required by local codes. If your system has more than one zone, add a filter, ¾-inch swivel adapter and a pressure regulator for each zone. Add a control valve and a battery controlled operator for automated systems.

3. Run ½-inch poly tubing near your plants. Keep a single dripper flow by placing the drippers into the poly tubing. Increase the size and number of drippers per plant based on plant size. Place drippers uphill from plants that are on a slope to prevent pooling at the bottom. Keep your space between drippers to 12 inches.

4. Maintain your system by inspecting drippers and tubing regularly to check for clogs. Flush filter screens once a month to remove buildup. Flush the line at least once a year.

Tips & Warnings

• Depending on rain amounts, you should run your drip watering system 45 minutes to 2 hours, 2 to 3 times a week.
