Spray Head Sprinklers
Pros: This system can be installed so the sprinkler heads are visible at all times or so they only pop up when the system is activated. This can be a purely aesthetic choice, but it is important to consider. Spray head sprinklers spray in shape patterns that range from circles to rectangles, with the various circle patterns being the most common. Some of the spray heads can even be adjusted to spray water from many different angles. This system is considered to have a high application rate, which means the sprinkler heads release a large amount of water in a short amount of time.
Cons: Due to their high application rate they are not the best system for slopes or for nonabsorbent soils, such as clay and sand. This system works best for flat areas. However, it is not impossible to use them with slopes and nonabsorbent soils; it just takes a little more work. The system needs to be specially programmed to reduce any run-off that may occur. Spray head systems do not cover as much ground as some other systems, so they are best for small areas, such as gardens and small lawns.
Rotor Head Sprinklers
There are two types of rotor head sprinkler systems: stream and impact. The stream rotor head sprinkler uses pressurized water to move the gears inside the head, which rotates the sprinkler head around. The impact rotor head sprinkler uses a swinging arm to rotate. When the arm swings it hits the sprinkler head and moves it a little.
Pros: The rotor head sprinklers distribute water more evenly than spray head sprinklers do, which makes them ideal for larger areas like big lawns. They also have a lower application rate. The rotor head sprinkler system works better for slopes and nonabsorbent soils because of its lower application rate. With the lower rate there is less run off water, because there is less water to overwhelm the soil. These sprinkler heads spray water in circular patterns of different sizes, and certain heads can be adjusted to different angles.
Cons: Since both types of rotor head sprinkler systems require pressure, the most common issue is having low pressure. This can especially be true in residential situations where there is usually lower pressure than in commercial situations. Impact rotor sprinklers also often need more maintenance than other types of sprinklers.
Drip Watering Systems
This system is completely different from a conventional watering system; it doesn’t use sprinklers at all. It uses a special tube with specifically placed holes in it that allow water to drip directly onto the soil.
Pros: The system is easy to customize because the holes can be placed anywhere along the tube. The tube can use a generic hole pattern for even distribution, or the holes can be placed at specific points to only water the plants and avoid watering the soil in between. This system also conserves water, because it drips water on to the soil instead of spraying it in the air which causes more evaporation. This system works great for gardens.
Cons: The system does not work very well with lawns, because it does not distribute water very far. Also, if you want to change the location of the holes in the tube for any reason, you need to buy a new tube.
Another key point about sprinkler systems is they need regular maintenance checks. These checks are important because they make sure your system is working right.
