Adjusting sprinkler heads is an essential task that every homeowner with a sprinkler system should know how to do. Hunter sprinkler heads are a popular brand of sprinkler heads used in many homes. However, it can be challenging to adjust them without the key. Fortunately, adjusting Hunter sprinkler heads without a key is possible, and it’s a simple process that you can do on your own.
The first step to adjusting Hunter sprinkler heads without a key is to locate the fixed right stop. Once you find the fixed right stop, turn the nozzle clockwise until it stops at the right fixed arc stop and hold it in that position. After that, use a hex wrench or plastic key end to adjust the arc located on the left side of the sprinkler head to regulate the water spray direction. With each full 360° turn of the wrench, the arc will increase by 90°. Adjust the arc to any angle between 40° and 360°.

When it comes to maintaining your lawn, having a reliable sprinkler system is crucial. However, even the best systems can experience issues from time to time. Here are some common issues that you may encounter with Hunter sprinkler heads, along with some tips on how to troubleshoot them.
Water Pressure Issues
One of the most common issues that you may encounter with your sprinkler heads is a lack of water pressure. This can be caused by a variety of factors, including a clogged nozzle, a faulty valve, or a leak in the system.
To troubleshoot this issue, start by checking the water pressure at the source. If the pressure is low, you may need to adjust the flow control valve or replace a faulty valve.

To troubleshoot this issue, start by checking the alignment of the sprinkler head. Make sure that it is pointing in the correct direction and that it is level. If the head is misaligned, use a wrench to adjust it.
If the head is aligned correctly, check the nozzle for damage or debris. If the nozzle is damaged, replace it with a new one. You may also want to check the nozzle size to ensure that it is appropriate for your system.
Water Pooling Issues
Finally, you may encounter issues with water pooling around your sprinkler heads. This can be caused by a variety of factors, including a misaligned head, poor soil drainage, or an incorrect nozzle size.
To troubleshoot this issue, start by checking the alignment of the sprinkler head. Make sure that it is level and pointing in the correct direction. If the head is misaligned, adjust it using a wrench.
If the head is aligned correctly, check the soil around the head for drainage issues. You may need to add soil amendments or install drainage tiles to improve the drainage in the area.
