Impact Irrigation Sprinkler Heads Explained and Compared

Impact irrigation sprinkler heads are a crucial part of any effective irrigation system. They come in different types, each with its own unique characteristics and benefits.

Fixed spray sprinklers are the most common type, emitting a wide fan-shaped spray of water over a fixed distance. Their simplicity and affordability make them a popular choice for many homeowners.

Pop-up sprinklers are another popular option, designed to retract into the ground when not in use. This feature helps prevent damage from lawnmowers and other yard equipment.

Impact sprinklers, on the other hand, use a rotating arm to distribute water in a circular pattern, providing even coverage over a large area.

Impact irrigation sprinkler heads come in different types, each with its own unique features. Impact rotor sprinkler heads, for example, have been around for a long time and are known for their classic sprinkler head noise.

They're a great choice for large residential properties with access to only hard water or ditches, as well as large garden beds and commercial properties. Impact rotors can cover a larger area, with arc patterns ranging from 40 to 360 degrees and a water pressure range of 25 to 50 psi.

The coverage distance of impact rotors can be as short as 20 feet or as long as 150 feet, and they offer a precipitation rate between 0.1 to 1.5 inches per hour. The radius arc is easily adjusted, making them a versatile option for many landscaping needs.

Here are some key characteristics of impact rotor sprinkler heads:

Traditional Rotor Heads are a classic choice for irrigation systems. They've been around for a long time and are still widely used today.

Impact rotor sprinkler heads are a type of traditional rotor head. You'll recognize them by the noise they make as they rotate. They're designed to cover a larger area, with arc patterns ranging from 40 to 360 degrees and a coverage distance of 20 to 150 feet.

These heads are great for properties fed by well water, ditches, or hard water, which can be tough on other types of sprinkler heads. They're also a good choice for commercial properties.

Here are some key benefits of traditional rotor heads:

Impact rotors are constructed out of bronze or brass, which makes them more expensive than newer plastic sprinkler heads. However, they're also more durable and require less maintenance.

Impact heads are designed for dependability, with an uninterrupted water flow and clog-resistant design, even when used with dirty or reclaimed water.

They're perfect for large-area watering, with a spray diameter of up to 90 feet, making them ideal for covering a lot of ground.

The deflector shield allows for distance adjustment, while the anti-backsplash arm helps with spray pattern and area coverage.

A simple twist of the diffuser screw breaks up the water stream, creating larger or smaller water droplets for more efficient watering.

Impact sprinkler heads have been around for a long time, with the first one invented by Orton Engelhardt in 1933. They're a type of irrigation sprinkler that's driven in a circular motion by the force of the outgoing water.

Impact heads are designed to cover a large area, with arc patterns ranging from 40 to 360 degrees and a water pressure range of 25 to 50 psi. They're also known for their durability and can last for years.

One of the defining features of impact heads is their uninterrupted flow path, which makes them less vulnerable to damage and clogging by dirt and sand in the water. This makes them suitable for systems fed by well water.

Impact heads are available in both metal and thermoplastic materials, with the latter offering improved corrosion resistance since the 1970s. They're also known for their long spray radius and uniform water distribution, which re-creates the effect of natural rainfall.

If you're looking for a reliable impact head, consider the Orbit 1/2-in. Male-Threaded Brass Impact Head, which lets you replace or add an impact head to your yard's watering system. It's designed for dependability and features an uninterrupted water flow and is clog-resistant.

Here are some key features of impact sprinkler heads:

Impact heads are a great option for large residential properties with access to only hard water or ditches, as well as large garden beds and commercial properties. They're also durable and can last for years, but may be more expensive than other types of sprinkler heads.

Impact irrigation sprinkler heads use a weighted, spring-loaded arm propelled by water pressure to create circular movement. This type of sprinkler head is known as an Impact Drive.

Water pressure, measured in pounds per square inch (PSI), affects the type of pipe and sprinkler head required for efficient operation. A sprinkler head's precipitation rate, or depth per hour of operation, is typically expressed in inches per hour.

A sprinkler head's radius arc and arc pattern determine the degree of coverage it applies. For example, a 360-degree circle covers the entire area, while a 90-degree arc covers a quarter of the area.

Here's a quick rundown of common irrigation terms to keep in mind:

The 35ADJTNTB – ¾” Inlet Brass Impact Sprinkler features a rugged all-metal construction, making it last longer than competitor's zinc sprinklers.

It's constructed of brass, bronze, and stainless steel, ensuring durability and longevity.

This sprinkler is designed for long-life and heavy-duty use, making it perfect for medium and large lawn areas, as well as gardens and landscaping.

Here are some key features of the 35ADJTNTB:

The 35ADJTNTB also features a straight-through flow design for superior performance with dirty and reclaimed water, making it ideal for use in irrigation canals, ponds, and areas with high-mineral content.

The 35ADJTNTB - ¾" Inlet Brass Impact Sprinkler is a top-selling model, and for good reason. It's a traditional favorite with a classic impact sound.

Here are some key specs for the 35ADJTNTB:

This sprinkler is designed for long-life and is perfect for use in medium and large lawn areas, as well as gardens and landscaping. It's also ideal for use with dirty and reclaimed water, thanks to its straight-through flow design.

The new X500 model features a gear-driven transmission, which provides smoother and more precise shifting.

This design allows for better control and reduced wear on the gears, resulting in a longer lifespan.

The gear-driven system also enables the X500 to achieve higher torque and faster acceleration.

With the gear-driven transmission, you can expect improved fuel efficiency and reduced emissions.

This technology is a significant upgrade over the previous model's belt-driven system, which was prone to slipping and overheating.

The gear-driven system is also more durable and requires less maintenance, making it a reliable choice for heavy-duty use.

When deciding on an impact irrigation sprinkler head, consider the type of water source you have. You may need a different type of head if you have a well or a municipal water supply.

The design of your property is also a crucial factor, including the slope and soil type. This will determine whether you need a gear-driven rotor, an impact rotor, or a pop-up rotator.

The three different types of sprinkler heads are designed for different applications, so it's essential to choose the right one for your specific needs.

When installing a sprinkler system, the costs can add up quickly. The real expense comes from the water pressure systems, underground components, and accessories like water pumps, which can be a significant investment.

Water holding tanks, pipes, and valves are also major contributors to the overall cost. For example, a system can range from $3,500 to $6,500 depending on the size of your property.

You might be able to save a few hundred dollars by opting for the least expensive sprinkler head, but it's essential to consider the entire system's cost.

Here are some of the key components that make up the cost of a sprinkler system:

To determine the best sprinkler head for your property, consider the type of water supply you have. Impact rotors are ideal for areas with low water pressure.

The design of your property is also crucial, as it affects the type of sprinkler head needed. For example, if you have a slope, a pop-up rotator might be the best choice.

Deciding between impact rotors and gear-driven rotors depends on the soil type of your property. Gear-driven rotors perform better in areas with dense soil.

Your local climate and weather patterns also play a role in choosing the right sprinkler head. If you live in an area with heavy rainfall, you may not need a sprinkler head that can handle high water pressure.

In some cases, you may need all three types of sprinkler heads – impact rotors, gear-driven rotors, and pop-up rotators – to cover all areas of your property effectively.
