Depending on the dimensions of the garden we can use the manual irrigation system or if the dimensions are very large and the time we have is limited we have automated irrigation systems, finding the drip and the sprinklers as the most popular.

Installing a sprinkler system in your garden is a good idea, especially during the hot summers when the plants in your garden or lawn need more frequent watering to survive. The installation of an irrigation system is not easy and is best done by a professional, but the adjustment of the head of a sprinkler if it is something that we can do by ourselves. It is very important to have correctly adjusted the sprinklers since a bad adjustment can mean leaving areas without any irrigation so they would dry out or areas with excess irrigation, both very damaging options. Today in this post we will show you how it is done.

If we observe carefully, we will see that the heads of the sprinklers follow a different pattern, for example, those installed in the centre of the garden rotate at 360 °, those that are installed along the edges rotate at an angle of 50 ° and those at the corners, at 45 °. This arrangement is preferred because it ensures that there is no overlap in the coverage areas of the sprinklers.

There are different types of irrigation heads available, but an emerging sprinkler is the most common. The mechanism and the design of a sprinkler allow adjusting the head to regulate the flow of water. It can be easily adjusted by turning the tip of the nozzle and the screw.

How to adjust the head:

The first step in adjusting a sprinkler head is to adjust the water pressure of the source. By doing so, you can decrease the area covered by the sprinkler or increase it by increasing the pressure. Once it has been determined that the water pressure is adequate, it is time to establish the position of the head of the sprinklers at a particular angle. Adjust the direction of the head of each one in such a way that there is no obstacle in the path of the water expelled by the sprinklers when they are in use. Here we will learn how to adjust a pop-up sprinkler to change the radius and height of the bow and much more.

Fixed side adjustment (end stop)

One side of the sprinkler head must be fixed, while the other side rotates to form the bow angle. Whether you choose to fix the right or the left, it’s up to you to decide and there are two ways to do it. The first method is to remove the dirt around the sprinkler head, firmly grasp the entire sprinkler assembly and rotate it to the desired position. Another way to do this is to completely remove the inner assembly from the rotating head and put it back in the desired position.

Arc Adjustment

The arc is defined as the angle formed by the rotating model. If you take into account the sprinkler is installed inside a circle, then the part of the circular area to be covered by the sprinkler determines its arc of rotation. Let’s say, you want the sprinkler to spray water to a semicircular area, then the angle of rotation should be 180 °. In other words, the angle formed by the rotating sprinkler between the two stopping ends is the angle of rotation and the path of this covered mode will be the arc.

To adjust the arc of the sprinkler, here is what to do :

  • Locate the adjustment hole in the top of the sprinkler head.
  • Turn the turret to the right stop and hold it firmly.
  • To increase the arc angle, insert the plastic head of the key into the adjustment hole and turn clockwise. It can rotate at a maximum angle of 360 °.
  • To decrease the arc angle, use the plastic head of the wrench to rotate the adjustment hole in the anti-clockwise direction. Note that the minimum arc angle is 40 °.

Radio Adjustment

The radius of the sprinkler is defined as the distance from the sprinkler head to the furthest point where the water arrives. Suppose that the sprinkler is in the center of a circle and we have chosen to set the sprinkler arc to irrigate a semicircular area. But how big would that semicircle be? To determine this, it is necessary to set the radius of the sprinkler. That is how:

  • Locate the radio adjustment screw on top of the head.
  • To increase the radius, turn the screw counterclockwise.
  • To decrease the radius, turn the screw clockwise.

In addition, the use of a smaller nozzle decreases the radius during use of a larger one means the sprinkler sprays water over a larger radius.

As we have seen, adjusting an emerging sprinkler is not that difficult after all. You can even install a timer to make sure the garden or lawn is watered regularly, even in our absence.
