Irrigation Sprinklers from Impact to Flush

So, you're ready to keep your landscape lush and lovely with a sprinkler system, but feeling overwhelmed by all the lawn sprinkler options? Don't sweat it! This guide will walk you through the wonderful world of irrigation sprinklers with zero technical headaches.
Impact Sprinklers: The Classic Workhorses
Remember that distinctive tick-tick-tick sound from childhood summers? That's the calling card of impact sprinklers! These trusty veterans of the irrigation world have been keeping lawns green for decades.
How They Work: Impact sprinklers operate using a spring-loaded arm that's pushed by water pressure. As the arm swings back, it creates that signature clicking sound while propelling water across your lawn. Simple yet effective!
Perfect For: Large areas like expansive lawns, sports fields, and agricultural applications.
Smooth Sailing with Any Water: One of the biggest superpowers of impact sprinklers is their ability to handle dirty or effluent (waste) water without clogging. While other sprinklers might throw a fit with less-than-pristine water, impacts keep on ticking!
Pattern Adjustment Made Easy: Need to adjust your coverage? Impact sprinklers offer straightforward pattern control with:
- Adjustable trip pins to set the arc of coverage
- Diffuser screws to control spray distance
- Easily accessible adjustment points that don't require special tools
Water-Saving Tip: Modern impact sprinklers can be adjusted for distance and arc, helping you target exactly where the water needs to go without wasteful overspray.
Rotors (Gear Drives): Smooth Operators
If impact sprinklers are the noisy old-timers, rotors (also known as "Gear Drives") are their smooth, quiet cousins that get the job done with a bit more finesse.
How They Work: Rotors use internal gears powered by water pressure to rotate smoothly in a pre-set arc. No clicking, just a steady stream of water that rotates silently.
Perfect For: Medium to large landscape areas where you want consistent coverage without the soundtrack.
Water Conservation Champions: Gear drives typically use 30% less water than impact sprinklers while covering the same area. That's like getting the same job done while taking fewer trips to the gas station!
Adjustment Options Galore: Unlock your landscape's potential with precise control:
- Adjustable arc patterns (often from 40° to 360°)
- Distance control through simple set screw adjustments
- Orbit Voyager rotors feature numbered nozzles for quick identification (1 for 90°, 2 for 180°, and 4 for 360°)
- Low trajectory nozzles available for water savings in windy areas
- Number 8 Nozzle for pasture or field applications
- Every nozzle offers matched precipitation rates to keep your lawn green
Clean Water Required: Unlike their rugged impact cousins, rotors prefer cleaner water to keep their precision gears running smoothly. Think of them as the sophisticated relatives who prefer filtered water.
Quick Win: Most rotors are incredibly easy to adjust – just use a screwdriver or adjustment tool to change the arc or distance. Your neighbors will appreciate the lack of accidental driveway watering!
Spray Heads: Versatility Champions
Now we're getting into the multi-talented members of the sprinkler family. Spray heads are the versatile performers that can handle a variety of watering needs.
How They Work: Spray heads deliver a fixed (or adjustable) spray pattern from a pop-up body. When water pressure activates, the head rises from the ground and sprays in its designated pattern.
Tech Made Easy - Check Valves: Spray heads can come equipped with built-in check valves that prevent low-head drainage. This smart feature:
- Stops water from draining out of the lowest heads when the system shuts off
- Saves gallons of water with each irrigation cycle
- Helps pop-up heads rise faster when the system turns on
Check valves, although sounding complex, are usually just an O-ring or washer that fills the space between the stem and can of the spray body.
Tech tip: Watch out for nozzles that sit flush on the cap. This can indicate that the check valve is not working. The check valve should force the nozzle to sit slightly above the cap.
Fan Spray Nozzles
The Classic Choice: Fan spray nozzles distribute water in familiar patterns like full circle, half circle, or quarter circle.
Perfect For: Smaller areas and oddly shaped spaces that need consistent coverage.
Adjustable Options Available: When standard patterns don't quite fit your unique space, adjustable arc nozzles come to the rescue! These clever nozzles let you dial in the exact arc pattern needed—perfect for those tricky spots where standard patterns just won't cut it.
Orbit Advantage: All of Orbit's spray nozzles are designed to have matched precipitation rates. What does that mean? Whether you have 4 quarter-pattern nozzles, 2 half-pattern nozzles, or 1 full-pattern they will all distribute the same amount of water.
Rotator Nozzles
The Efficiency Stars: Unlike traditional spray heads that mist water, rotator nozzles deliver multiple rotating streams of water.
Why You'll Love Them:
- Use up to 30% less water than traditional sprays
- Provide more uniform coverage
- Reduce runoff with their slower application rate
- Work well even in windy conditions
The Game-Changer: Pressure-Regulating Spray Heads
Let's talk about one of the smartest upgrades you can make to your irrigation system: pressure-regulating spray heads. Think of these as the brilliant problem-solvers of the sprinkler world.
What Makes Them Special: Unlike traditional full-flow spray heads that operate at whatever pressure comes their way, pressure-regulating heads maintain optimal pressure regardless of what's happening in your main water line.
The Advantages Are Clear:
-
Consistent Coverage: Say goodbye to dry spots and puddles! By maintaining the ideal pressure, these heads deliver water exactly as the nozzle manufacturer intended.
-
Dramatic Water Savings: Reducing excess pressure can save 20-40% of water compared to non-regulated heads. That's not just good for the planet—it's great for your water bill.
-
Misting Elimination: Too much pressure creates tiny water droplets that drift away before reaching your plants. Pressure regulation keeps water droplets the perfect size to land where they should.
-
Extended System Life: High pressure is like highway speeding—it causes more wear and tear. Regulated heads reduce stress on your entire irrigation system.
-
Reduced Maintenance: Less pressure means fewer blown nozzles, broken seals, and leaking heads. Your future self will thank you!
Spotlight on Orbit PR Heads - Adjustability That Adapts: Orbit pressure regulating spray heads take efficiency to the next level with adjustable pressure settings:
- Easily toggle between 30 PSI (perfect for standard fan spray nozzles) and 40 PSI (ideal for rotator nozzles)
- Clear "PR" marking on the cap for quick identification in the field
- Same standard size and installation as regular spray heads for hassle-free upgrades
Tech Made Easy: Most pressure-regulating spray heads look almost identical to standard models, making them a simple swap-out upgrade that delivers instant benefits.
Shrub Heads: The Specialized Squad
When you need water delivered right to specific plantings, shrub heads step into the spotlight.
How They Work: Similar to spray heads but mounted on fixed risers instead of pop-up bodies, shrub heads sit permanently above ground level.
Perfect For: Flower beds, shrub areas, and anywhere you need targeted watering that rises above plant material.
The Orbit Advantage: Orbit offers an impressive lineup of shrub head options to match your precise needs:
- Traditional shrub head bodies for standard applications
- Pressure regulating models for optimal water efficiency
- The game-changing Titan – a rotor mechanism on a ½-inch FPT socket that delivers up to a 25-foot radius with all the water-saving benefits of a gear drive rotor
Smooth Sailing Tip: Position shrub heads carefully to ensure water reaches plant roots without wasting a drop on walkways or patios.
Flush Heads: The Ground-Level Guardians
Rounding out our sprinkler family are the low-profile flush heads that keep a low profile while delivering stellar performance.
How They Work: These heads sit flush with the ground and don't pop up. Instead, they deliver water from their stationary position.
A Bit of History: Flush heads are almost as vintage as impact sprinklers, though they're gradually becoming less common in modern installations. Traditionally installed on fixed risers, many landscapers now opt to replace them with pop-up spray heads on swing joints (a topic we'll cover in a future blog post!).
Perfect For: Areas where pop-ups might be hazardous or impractical, like along walkways or in areas with heavy foot traffic.
Quick Win: Flush heads are virtually invisible when not in use, making them perfect for areas where aesthetics are important.
Choosing the Right Sprinkler: Your Action Plan
Still wondering which sprinkler type is perfect for your sprinkler system? Here's a simple decision guide:
- Large, open areas: Impact sprinklers or rotors
- Medium-sized regular shapes: Rotors or spray heads
- Small or irregularly shaped areas: Spray heads with appropriate pattern nozzles
- Water conservation priority: Pressure regulating spray heads
- Flower beds and plantings: Shrub heads or the Orbit Titan
The Distribution Uniformity Rule: For optimal performance, avoid mixing different sprinkler types (impact, rotor, spray, etc.) within the same zone or station.
Orbit sprinklers are specifically designed with matched precipitation rates in mind, meaning they apply the same amount of water across their coverage area when used together. This uniformity ensures your landscape gets evenly watered without dry spots or soggy patches.
