Best Rotating Lawn Sprinklers: What are they?
The term “rotating” refers to the fact that there are multiple units, each with its own settings. Each unit controls a different amount of water, depending on how much rain it receives during the day. The sprinkler’s rotational speed determines how fast it turns (or spins) and thus whether or not the water is turned on at all.
Rotary sprinklers are used in many types of landscapes. They’re most common in lawns where you want to ensure that the grass gets watered evenly throughout the day.
Some models have a timer function so you don’t need to worry about turning them off when your workday ends. Others allow you to set specific times for watering, such as before bedtime or before leaving for vacation.
Why Use One?
There are several reasons why you might choose to use a rotating sprinkler instead of a standard one. You may prefer the ability to turn on and off the sprinkler manually rather than having it automatically do it for you. Or perhaps you’d like to control the amount of water that reaches certain areas of your yard without having to constantly adjust the size of the sprayer nozzle. Either way, a rotating sprinkler will make watering your lawn easier!
How It Works
Rotary sprinklers typically have multiple heads, each of which is attached to a disk that can rotate independently of the other nozzles. Most of these are driven by an electric motor and work on a timer.
When it’s time for your lawn to be watered, each head begins to spin slowly over the area that needs to be watered. As it passes over the soil, the water is released in a circular pattern.
As the sprinkler makes another rotation, it’ll water a different patch of grass. You can adjust how much area each head is responsible for watering as well as how long each one stays on.
There are many types of rotary sprinkler nozzles to choose from. Some have straight streams while others have a fan-like spray.
A few models even release an aerated stream that looks similar to a fire hose! These are perfect for getting moisture down deep into the soil.
What Type Do You Need?
If you’re looking to water a small area, such as a flower garden, a hand-held sprinkler is the perfect choice. These can either be attached to a hose with a spray nozzle or have the ability to plug into any outdoor outlet.
If you’re watering a large surface area, like your lawn, you need something that will cover more ground with each rotation. A stationary sprinkler with an adjustable spray nozzle is the best way to water a large area evenly.
There are some nozzles, however, that offer a 360-degree spray so you can drench your grass in a circular pattern.
Rotating sprinklers are especially helpful for anyone with a large yard who doesn’t want to waste time or water over watering certain areas. There are even models that have a built-in timer and can be programmed to water at certain times throughout the day.
Also make sure to keep in mind the size of your yard when shopping for a sprinkler. A smaller yard will require less coverage than a large acreage.
Using the wrong sprinkler could result in uneven watering or worse, a leaky hose!
