Finally, combine small sprinkler heads into clusters of various circuits, and each cluster will be controlled by one valve. Next, group valves together and connect them to the irrigation controller. Afterward, arrange the pipes, sprinkler heads, fittings, and valves so they can function smoothly. Make sure the piping is the right diameter to supply consistent water flow.
GET STARTED NOW!
The main line from your water source is the most expensive run of piping that you’ll lay, so it’s best to keep these runs short. Of course, we don’t recommend putting all your boxes in the front yard, but you don’t want to space boxes all over the yard either. Once you have followed these steps and designed your sprinkler system, now is the time to install the irrigation system based on your design.

After considering all these factors, check out your landscape to decide where you should put sprinkler heads so they'll be effective during watering hours. Maintaining a healthy and flourishing lawn requires more than watering and regular mowing. You also need a well-designed sprinkler system that provides even and efficient water coverage. A carefully designed sprinkler system not only saves water but also saves you time and money.
Sketch your yard
What head you use will be determined by the size of the watering area. For areas larger than 25’ x 25’, you’ll want to use large area sprinklers (either gear driven or impact heads). Areas smaller than 25’ x 25’ will use popups (either traditional or rotary). For flower beds, shrubs, ground cover, etc. you’ll want to use small area sprinklers, drip, or soaker lines.

When mapping out the zones, it’s important to provide sufficient water pressure to each zone. All the heads in the zone combined must be using at or below the total available water flow (GPM). You might even want to step it down by 1-2 GPM just to make sure there is enough water in the case of a drop in pressure. Note how we’ve grouped the two zones on the right in the example above.
Residential System Design Guide
There are many different kinds of heads, and knowing which ones you need will help your design process go more smoothly. Then, determine where your water supply will be coming from (a well? city/town source?). Ensure there’s enough pressure available to provide an adequate flow rate throughout the entire area being watered. As their name implies, these sprinklers are effective in covering large areas of turf.
Check your water pressure
A great solution is low-volume drip irrigation that allows you to customize the water delivery to each plant individually. Designing a system with multiple independent zones allows you to schedule watering according to each area's unique watering needs. Attach the water pressure gauge to an outside faucet, turn on the water and record the reading in pounds per square inch (PSI). Most automatic sprinkler systems require between 40 to 60 PSI to operate properly. Knowing these two things, you can begin to group your heads into zones.
Correctly choosing your sprinkler heads is one of the most necessary steps in designing your sprinkler system. There are various types of sprinkler heads, and their choice varies depending on the watering needs of your zone. Some types include Rotor sprinkler heads, spray heads, fixed sprays, bubblers, solid stream rotors, and drip irrigation. All these sprinklers feature different flow rate, pressure, and coverage. This booklet is intended to be used when designing and installing small, single-family residential sprinkler systems.
Water flow and water pressure are two imperative aspects of any sprinkler system operation. You need to measure the water pressure and flow rate to ensure proper coverage and to design an accurate system. Insufficient water pressure can be the cause of sprinkler system failure. Designing an automatic sprinkler system for your home can seem daunting, but following these simple tips will help make the process easier. Our Rain Bird Sprinkler Design Service can help you make your personalized plan.
If you have any questions on the design or installation process, your best resource is your local Hunter distributor. Pop-up, gear drive, and impact sprinkler heads work great for the lawn but they aren’t precision instruments. These will work well if you have a lot of ground cover, but what if your beds just have shrubs, flowers, etc.?
The pop-up Eco-Stream Rotator Sprinkler Head is a hybrid between pop-ups and rotors. Often called the rotary sprinkler, it looks like a popup, but behaves like a handful of gear drives being sprayed in a kaleidoscope pattern. Further, they offer the adjustability of rotors with the effectiveness of popups.
Often sprinklers waste water on sidewalks and driveways or spray against the house or garage. The final steps of designing your home sprinkler system are to draw a layout of the zones and then calculate your design’s water requirements. As you’ll see, the process of planning a sprinkler system can be a worthwhile challenge.
