It is necessary to know the GPM for each head in order to determine which heads will be connected to each valve and in order to determine the size of each pipe in the sprinkler system. For example, if you space the sprinklers 45′ apart, you must have at least 45 PSI of pressure at the sprinkler inlet. Protecting Pump against No Flow Damage if a Valve Fails. The writers of those brochures think you are going to look at the overlap and buy the brand of sprinkler that shows the least sprinkler heads. If the sprinklers need to overlap so that the spray from one head goes over and beyond the next that’s OK. Stream heights range from rom … You’re now ready to pencil in the sprinkler head locations on your drawing. Sprinkler Rotors, Sprayers, and Nozzles. Find the pattern (1/2, full circle,etc.) So don’t stretch the distance between sprinklers. One more time: The water from any single sprinkler should actually get the sprinklers on each side of it wet! Sprinkler Nozzles Sprinkler nozzles, also referred to as spray nozzles, are an important, but often overlooked component of well-designed irrigation systems. Note that in the example above only the lawn area outlined with a green curving edge is being watered. Rain Bird 751 . 1/4 circle . Impact Sprinklers. They don’t show enough overlap! 30h 30wh Rain Bird. This large sprinkler features excellent uniformity, long-lasting dependability, and is made for commercial agriculture.

Try to position heads so that if you were to draw a straight line between adjacent heads they would form an equilateral triangle (each side of triangle is same length). 5. R75 End of Pivot Sprinklers. Rotor heads move back and forth across the area to be watered. 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! No Comment, ExactApply: How to add “Section Flow %” Module to Run Screen. This will help avoid problems caused by the wind blowing the spray out of the irrigated area. Impact sprinklers tend to be better made – assuming you stay away from the cheap plastic versions. Adjust the locations to make the spacing between sprinklers as even as possible. (Optional reading for those who need explanations.) So the GPM of that sprinkler if you reduce the radius to 14′ will be 1.65 GPM. A Nozzle for Every Occasion From the water-saving MP Rotator, to standard sprays and side-stripped specialty nozzles, Hunter provides a solution you can trust for years on end. This is because the smaller heads with lower GPM rates are more susceptible to wind and evaporation, and thus it is assumed less of the water is actually reaching the ground. That’s the pressure at the sprinkler inlet, not the total pressure available. You may want to make additional adjustments to nozzle sizes after installation to compensate for your specific conditions. $21.73. That’s because when turn the radius adjustment screw to reduce the radius to 14′ what you REALLY did was reduce the pressure to 25 PSI! Remember, you will lose pressure in the pipes and valves, so the pressure at the sprinkler inlet will be lower than your available pressure! You need to trust me on this one! The other solution for smaller areas is to use nozzles made to spray less far, or that spray a special pattern. 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. .55 PSI – 3.0 GPM 3/4 circle . There is a conflict between the nozzles recommended for the 20-29′ spacing range of the chart and my previous advice to “avoid using rotors with nozzle flows that are less than 2.5 GPM”. When the manufacturer tested the rotor on their test range (inside a large building with no wind) they measured a few drops of water 32′ from the rotor. So why am I telling you to space it at 25′? Trashbuster. SKU: NAAN-5022-R. Only 41 left! I still recommend that you keep at least 80% of the sprinklers at head-to-head spacing! . For example, 15′ radius spray heads should never be more than 18′ apart (30′ diameter x 0.6 = 18′). For example, you can use the radius adjustments on the sprinklers to cut down the water in the over-irrigated areas. Once you’ve encountered your travel speed, move along the row to the left to identify the nozzle size and spray pressure. 24 ft 45 pop up impact sprinkler rain bird 2045pj maxi impact spreader nozzle for impact sprinkler rain bird spray nozzle chart toskin 3500 rain bird sprinklers ewing. .

The area between the lawn (green line) and the edge of the property (brown line) would most likely be planted with shrubs and irrigated separately from the lawn. So the GPM of that sprinkler if you reduce the radius to 14′ will be 1.65 GPM. To change the radius a small screw extends into the stream of water coming out of the nozzle. Software. Again, notice that the radius of each sprinkler’s spray goes all the way to the next sprinkler! Looking at the manufacturer’s literature you note that a radius of 14 ft. for the 1/2 circle nozzle in this sprinkler requires a pressure of 25 PSI and a flow of 1.65 GPM. The perfect sprinkler would put out a pattern of water that is heaviest right next to the sprinkler, then uniformly declines out to the radius. As with the example above, it is best if you arrange the sprinklers in a triangular pattern. . . Now that I’m a bit wiser and more knowledgeable I realize there is a good reason behind the head-to-head coverage. The Rain Bird company makes many different types of sprinkler heads, including impact rotors. (Remember most manufacturer’s give you the radius of the sprinkler, you need to multiply by 2 to get the diameter.) . Sprinklers that are placed closer than 6 feet apart need some special consideration. Sprinkler gpm equals 300 divided by time (seconds) to fill 5-gallon bucket. Stream heights range from 0.8 to 1.7 m above nozzle based on pressure and nozzle size. Brass Range Nozzle For Impact Sprinkler (10 Pack) - We offer several sizes of range nozzles for Wade Rain's WR-33 and WR-35 Impact Sprinklers. nozzle face. Sprayhead. The proper nozzle ensures accurate, even delivery of water in the pattern you need. It is critical that the water pressure (PSI) at the sprinkler be as high, or higher, than the distance between the sprinklers in feet (per Stryker’s Rule). Bottom line- use the radius adjustment screw on rotors only when nothing else will work. A lot of those free design guides you find in stores and on the Internet get this wrong. They get those distances by testing the rotors inside a building with no wind. A border using shrubs of various sizes, textures and colors can add greatly to the attractiveness of your yard. Standard spray-type sprinklers don’t work well if the radius is adjusted below 6 feet. When we test sprinklers for water coverage we set up a series of cups between the sprinklers to collect the water that falls. If possible always install a side-strip in the middle between 2 end-strips. After you’ve bought the sprinklers if you have dry spots, well hey, it’s YOUR problem now!

What if you need a smaller radius than the sprinklers available? Most rotors now come with a “nozzle tree” that contains most of the different nozzles for the rotor, so you can change the nozzle sizes if you need to. Pop-up sprinklers and nozzles a great for small areas. The tip of the screw deflects the water which “screws it up” (pun intended) so it doesn’t go as far. Not a good start for a future irrigation expert! Record nozzle size(s) and check nozzles for wear by inserting shank end of a new drill bit (same size as nozzle) into operating sprinkler. Once a month you need to weed and trim shrub areas, as opposed to the lawn that needs to be mowed every other week at the least in summer.

Hunter offers an assortment of nozzle options for any lawn sprinkler system — adjustable, fixed, specialty nozzles, and revolutionary MP Rotator nozzles. Almost all sprinklers have a radius adjustment device on them so that you can reduce the radius of the water throw. For example, if you are looking at a 25′ radius, the chart above says to use a 1.6 GPM nozzle for a half-circle rotor. Keep in mind that for most sprinklers you can’t reduce the radius by more than 50% without causing problems. Make sure that your travel speeds are achieved at a pressure that’s right for the nozzle you’re using. But, if the rotor does not spray far enough there is nothing you can do about it without a major expense! Only use recommended nozzle sizes and types for each model. . 1.

When you install it out in your yard it will not perform as well. Contact. 40 PSI – 4.5 GPM You can’t do it, can you? Orbitor FX. In this chart, identify your water volume along the top row, and follow the column until you encounter the travel speeds you’re interested in. For narrow strips wider than 5′ you would use regular half circle heads on both sides. A half circle rotor must have a nozzle that puts out 1/2 the water of a full circle. This is one way you can adjust for narrower areas. They also manufacture or distribute many other irrigation products.) Measure sprinkler discharge (gallons per minute) using a 5-gallon bucket, hose, and watch. So the spacing for this head is 14 ft. (the highest of the 3). Flows under 2.5 GPM give very poor coverage due to the tiny water stream. Another quick thing to mention is the durability of these two types of sprinklers. Rain Bird Spray Nozzle Chart Toskin.

By using this tutorial you agree to be bound by the conditions and limitations listed on the Terms of Use page. Other nozzle sizes are available. The other reason is that when you reduce the radius you really should also reduce the GPM of the sprinkler. When you use the radius adjustment on a spray you are simply reducing the water pressure by closing a small valve in the nozzle. Use a nozzle size that comes close to matching both the PSI – GPM combination. They are the world's most popular sprinklers and are preferred by professionals. Example: You note that a spray type head on your plan is a 1/2 circle pattern and the distance to the 3 closest adjacent heads are 13 feet, 12 ft., and 14 ft.. Otherwise you’ll wind up having to look the information up over, and over, and over…. Keep the distance as uniform as possible between heads.

In fact, it will probably take more sprinklers to fix the dry spots than it would have to do it right the first time. Ouch! 55 PSI – 11.0 GPM. Have Doubts? . In other words, use those listed in the chart for 30-39′ spacing for the 20-29′ spacing. Conversion Formulas    I prefer the so called “side-strip” type that you place along the edge of the area, they have better patterns than the center strip nozzles. This example shows the typical placement for sprinkler heads in a narrow planter. Right now you may be feeling pretty smug about how much money you saved by stretching the sprinkler spacing. . Precipitation rate must be considered when selecting your sprinkler heads to eliminate water application uniformity problems (dry spots). Looking at the manufacturer’s chart you see that the radius of the same sprinkler is 14′ at 25 PSI with 1.65 GPM.
