Not knowing how to adjust a pulsating sprinkler can lead to frustration, but adjustment is not as technical as you might think. With the steps below you can save time and money by adjusting your pulsating sprinkler yourself. The components of the sprinkler will allow you to adjust it without any extra tools.
Step 1 - Map out the Zone
Map the areas you would like the sprinkler to cover. Take note of the type, height, and density of plant cover. The sprinkler must be adjusted in such a way that water can reach the farthest extremes of its zone. Another important reason for mapping the area is to understand the soil’s water retention capability, all other factors being constant (such as the rate of evaporation). Soil that displays high water retention levels should receive less water than that with lower retention. Lastly, watering a lawn covered with low-cut grass is different from how one waters flowers and shrubs.
Step 2 - Check the Sprinkler Head for Damage
Examine the sprinkler head to confirm that there is no crack or blockage that may be causing irregular or low-pressure output. If the head is faulty, you'll have to replace or repair it.
Step 3 - Adjusting the Rate of Water Output
Push the depressible tabs on either side of the sprinkler nozzle to move the throughput to the desired level. This helps control the amount of water that leaves the nozzle. Run a full cycle through the sprinkler system to confirm the throughput before proceeding to the next step.
Step 4 - Adjusting Sprinkler Reach
Use the knob at the top of the pulsating sprinkler nozzle, to adjust how far you want the water stream to go. Directions on the knob will detail which side to turn it for further and which direction for closer. On some sprinkler models, you must apply pressure (using your hand) to the nozzle in order to turn the knob. Run a cycle through again as a test.
Step 5 - Adjusting Angle of Rotation
If the sprinkler is to be placed at a corner of the lawn or close to the sidewalk, having the sprinkler do a 360° will be wasteful. Different manufacturers manage rotational adjustment in different ways. Most pulsating sprinkler models come with a lever that blocks a set of protrusions on either side of the sprinkler head to prevent the full-circle rotation. You lift when you need the full-circle turn and lower it to hold it within the pre-set angle. Further, there are stops that enable adjustment of the angle of rotation.
