If you’ve decided to invest the time and money into irrigating your lawn, choosing the right sprinkler head is a must.

The proper sprinkler head will ensure proper water distribution and over time, will save you valuable time and money.

Yet, with so many sprinkler heads on the market today, it can be difficult to determine which is the best fit for your home and garden.

Today, we’re taking a look at a few considerations to keep in mind when picking yours out to take the guesswork out of your next trip to the hardware store.

Types of Sprinkler Heads: Finding One That Fits

One of the most important aspects of your selection will be picking the type of sprinkler head that’s appropriate for your intended use, it’s not just about budget! Let’s take a look at the top three most common types:

Spray HeadsSmart Irrigation sprinkler lawn perth

These are the most traditional types of sprinkler heads. They distribute water in a fan shape. You can usually interchange their nozzles to switch the pattern up, spraying water in a circular pattern, half circle, etc. These
types of heads are usually spaced around 18 feet apart, and you can adjust them to determine how far the water reaches.

Rotor Heads

These types of sprinklers work by rotating a water stream over your lawn in full or half circles. Due to their position, you can space rotor heads farther apart, typically between 8 and 65 feet.

Rotary Nozzles

These are essentially miniature rotors that fit onto smaller rotator bodies. They are designed to produce less of a stream, and more a light mist and thus, conserve water.

Selecting the Right One

Not sure where to start when deciding between these types of sprinkler heads? Here are some key points to think about:

Water Pressure

Spray heads require between 20-30 PSI of water pressure. PSI is the pressure of a column of water – about 0.433 psi per foot of water column height.

Rotor heads require at least a little more water pressure than the distance between rotators (so if your rotators are 45 feet apart, around 55 PSI). Rotary nozzles work the same way, but on a smaller scale.

If your water pressure is less than 40 PSI, you’ll want to consider spray heads or rotary nozzles. Rotor heads are typically designed to cover a larger area and thus need more PSI.

Shape of Area

Is your lawn wide and long? If so, the far-reaching rotor heads might be just the ticket. On the other hand, if it’s narrow, between 12 and 28 feet wide, rotary nozzles should work great. They have a water spray radius of between 15-35 feet and are ideal for smaller areas.

Landscaping Design

When planning your irrigation system, keep in mind the shape of your landscape, taking into account any curves and edges.

Think about what would happen if water sprayed past the edges of your sidewalks, garden beds, and more. Would it be OK, or would it cause damage? If you need to keep it contained, spray heads or rotary nozzles would be your better option.

How many times have your driven past a home or commercial property and seen more water on the road – and your car – than actually on the lawn? This isn’t just a waste of water and money, but leaves the lawn and grounds at risk of damage by over or under-watering. Getting a proper irrigation system with the correct fittings and optimised for location and pressure is the best way to save waste and keep your garden healthy!
