K-Rain sprinkler heads can be adjusted to ensure optimal watering for your lawn or garden. Here’s a step-by-step guide on how to adjust them:
1. Locate the adjustment screw on top of the sprinkler head.
2. Use a flathead screwdriver to turn the screw clockwise to decrease the spray radius or counterclockwise to increase it.
3. If you want to adjust the spray pattern, rotate the nozzle turret to the desired position.
4. For adjusting the spray distance, use the radius adjustment screw.
5. Test the sprinkler after each adjustment to ensure it is watering the desired area effectively.
Remember to make small adjustments at a time and test the sprinkler to achieve the desired coverage and watering pattern for your lawn or garden.
K-Rain sprinkler systems have simple methods for adjusting the coverage of your lawn without wasting water. To ensure all zones in your yard receive water, you can adjust each sprinkler head. While K-Rain’s K-key tool is often used for adjustments, a small flat-head screwdriver can be used as a substitute if the tool is not available. It is important to make adjustments with the water turned off.
Changing the Start Position
When you want a sprinkler head to rotate a full 360 degrees, there is no need to change the start position. This adjustment is only necessary if you want to avoid watering a specific area, such as the side of a building.
To remove the sprinkler head from the ground, insert the K-key into the keyhole on the top of the head. Turn it a quarter turn and use it as a handle to lift the sprinkler head. Grasp the lower riser assembly, which is the section directly below the top nozzle section. Locate the nozzle arrow on the top of the sprinkler head and rotate the assembly until the arrow points to the desired starting point for the spray.
Adjusting the Rotation
It is important to note that changing the start position does not limit the rotation of the spray to a specific area. K-Rain sprinkler heads can rotate between 40 and 360 degrees. By default, K-Rain sprinklers rotate a full 360 degrees.
To set a new stop position, insert the K-key into the arc selection slot in the center of the sprinkler top. Turn the key until the arrow on the slot points to the desired stopping point, which is indicated in degrees on the sprinkler. When adjusting the spray pattern, start at the lowest setting and turn the key clockwise to the desired setting.
Setting the Spray Distance
K-Rain sprinkler heads have interchangeable nozzles with different angles to adjust the spray distance. Ideally, the spray from one sprinkler head should overlap the spray area of all adjacent sprinkler heads. The spray should reach far enough to touch the adjacent sprinkler heads.
To change the nozzle and adjust the spray distance, remove the nozzle retention screw using the K-key. The screw is located inside the arrow, indicating the position of the nozzle on the top of the sprinkler head. Pull the sprinkler head out of the ground by sliding the K-key into the key slot and turning it a quarter turn. Press the K-key behind the prongs on the nozzle to pry it out. Insert the new nozzle with the prongs facing upward, and then reinstall the nozzle retention screw.
Adjusting the Sprinkler While Water is On
While you may get slightly wet, you can make minor adjustments to K-Rain sprinkler heads while they are spraying water. For small adjustments to the spray distance, loosen or tighten the nozzle retention screw with the K-key until the desired distance is achieved.
To change the rotation of the sprinkler head, turn the top nozzle section, known as the turret, to the right until it stops. Then, turn it all the way to the left, which will position the nozzle at its starting point. Use the K-key to turn the arc selection slot and arrow to the new setting. It is important to keep the settings between 30 and 360 degrees to avoid damaging the sprinkler head.
