Before You Design

To insure the most efficient irrigation system design, use a professional irrigation designer and installer. The Irrigation Association (IA) at certifies irrigation designers. The California Landscape Contractors Association certifies irrigation installers.

If you decide to do it yourself, follow the steps below:

  • Determine the water pressure in your neighborhood, attach a pressure gauge to a faucet nearest the irrigation system’s point of connection to the home’s water supply. Pressure gauges are available at many hardware stores. Knowing the site’s static water pressure is very important in the design of an irrigation system that works properly.
