Not all sprinkler nozzles are the same, and choosing the right one can make a big difference in how your yard uses water.
If you’re wondering about the difference between spray nozzles vs. rotary nozzles, you’re not alone. They each work a little differently and are better suited for different parts of your landscape.
Spray Nozzles
- Deliver a fan-like, consistent stream of water.
- Operate best at lower water pressure (typically 15–30 psi).
- Have a shorter reach, usually up to 18 feet.
- Produce smaller water droplets, which makes them more prone to misting and wind loss.
- Typically less expensive, costing about $1–$3 each.
- Water quickly, applying about 1.0–1.5 inches per hour, which means shorter run times.
- Less likely to overspray in tight or small areas.
- Tend to have lower distribution uniformity, which can lead to brown spots.
- Usually last longer and require less frequent replacement.
Rotary Nozzles
- Spray multiple rotating streams of water.
- Designed for higher water pressure systems (typically 30–55 psi).
- Can reach a longer distance, often up to 24 feet.
- Produce larger water droplets, making them less likely to mist and more wind-resistant.
- Typically more expensive, costing around $4–$8 each.
- Apply water slowly, at about 0.25–0.5 inches per hour, so zones need to run 3–6 times longer than with spray nozzles — which can lead to long run times for larger yards.
- More likely to overspray in small or tight spaces.
- Offer higher distribution uniformity, which helps prevent brown spots.
- May need to be replaced more often due to wear or damage — clogged or damaged rotary nozzles can stop spinning or spin too fast.
Choosing between spray and rotary nozzles ultimately depends on your yard’s layout, water pressure, and water efficiency goals. Each type offers benefits, but it’s essential to use only one type per irrigation zone to avoid uneven coverage, dry spots, or overwatering. Take time to assess your landscape’s needs — and if you’re unsure, check your water provider’s resources or connect with a local irrigation professional.
