This will help avoid problems caused by the wind blowing the spray out of the irrigated area. Do not blow off my advice on sprinkler spacing in order to save a few bucks on sprinkler heads! Avoid operating a low-drift spray below 30 psi – its pattern will be too narrow and likely its spray quality will be too coarse for good results. Important! However, if your sprinkler system will be located in an area with little or no wind you can go ahead and use the smaller nozzles in the chart. The chart tells you the GPM the nozzle must have. Stream heights range from rom … Bonus landscape design tip: Creating a border of shrubs around the perimeter of your yard is, in most cases, a good landscape design practice.

Even a slight breeze will distort the watering pattern and give you dry spots. Page 1 of 1 Start over Page 1 of 1 . If all or a majority of your rotors will be spaced at 20-29′ apart, then you should probably use larger nozzles than I recommend in the chart. As we saw previously, the flow rate in gallons per minute (GPM) of each sprinkler head is determined by the nozzle installed in the head. . Ignore the radius given by the manufacturer. Rain Bird Impact Sprinkler Nozzle Chart. I still recommend that you keep at least 80% of the sprinklers at head-to-head spacing! What if you need a smaller radius than the sprinklers available? The other solution for smaller areas is to use nozzles made to spray less far, or that spray a special pattern. This is one reason I strongly suggest that you use a smaller nozzle if possible rather than using the radius adjustment screw on the sprinkler. Sprinkler nozzles, also referred to as spray nozzles, are an important, but often overlooked component of well-designed irrigation systems. Remember, if the sprinkler sprays too far, most rotors have a radius reduction screw that will allow you to very easily reduce the radius. So don’t stretch the distance between sprinklers. 1/4 circle . For 20-29′ spacing between sprinklers- Write down the flow of 1.65 GPM next to the sprinkler head on your drawing. .55 PSI – 3.0 GPM See the separate guidelines for designing drip irrigation systems. When designing systems with rotors do NOT rely on the manufacturer’s stated radius for design. Select the nozzle size closest to these GPMs without regard to the radius the manufacturer gives. So the GPM of that sprinkler if you reduce the radius to 14′ will be 1.65 GPM. The proper nozzle ensures accurate, even delivery of water in the pattern you need. Looking at the manufacturer’s chart you see that the radius of the same sprinkler is 14′ at 25 PSI with 1.65 GPM. As with the example above, it is best if you arrange the sprinklers in a triangular pattern. They tend to have a weak coverage area on either side of the nozzle (the yellow area in the drawing above). Important: see notes below! ), as winds over 10 mph really mess up the sprinkler patterns. • In the diagram below you can see what happens when there are various distances between the sprinklers. In other words, if the planter is 8 feet wide you would install half circle heads on both sides of the planter, not more than 9 feet apart from each other. Tom focuses on practical advice that is research-based to improve the efficiency of producers. O.K. To match the precipitation rates between these sprinklers, the quarter circle rotor must have a nozzle that puts out 1/4 the amount of water that the full circle nozzle puts out! $$$ Ching, ching!

For 30-39′ spacing between sprinklers- If you have rotors that are adjusted for different radii you will need to adjust the nozzle size to compensate for the radius change also! The tip of the screw deflects the water which “screws it up” (pun intended) so it doesn’t go as far. This is why when you buy a rotor-type sprinkler head they often include a handful of different size nozzles with it. Some manufacturer’s don’t offer nozzles sizes larger than 3.0 GPM for their economy-priced heads (providing those extra nozzles would probably cost them at least another nickel in costs!). Rotors: Rotor-type heads aren’t quite as easy. For most air-induced nozzles, this will be about 60 to 70 psi (highlighted). Find the pattern (1/2, full circle,etc.) 6. That means each sprinkler throws water ALL the way to the next sprinkler in each direction. Add to Cart. Now that I’ve told you that you SHOULD use head to head spacing I’m going to backtrack a bit and tell you that you can space a few of the sprinklers slightly farther apart as needed to work around odd shaped areas. Later on you will need to know the flow rate for each sprinkler you use, so it might be helpful to make some notes on the back of your Design Data Form showing the nozzle size and GPM you will need for each different sprinkler you plan to use.
