A Sprinkler Repair DIY Guide.
5 Simple Sprinkler Repair Tips.
1. Turn off the Water Supply.
Before you start any repair job, make sure to turn off the water supply going to your sprinkler. This is a very important step and needs to be done carefully in order to prevent unnecessary damage and accidents. Turn it off either at the main valve or at the hose valve on the side of your house nearest your sprinkler. Make sure all valves are completely shut, then proceed with the repairs.
2. Locate and Identify the Broken Sprinkler Heads.
Once you've cut off the water source, it's time to locate and identify the broken sprinkler heads. This can be done either in daylight or with a flashlight at night. Do a full inspection of your lawn and look for any sprinkler heads that are misaligned or leaking water, or perhaps even missing completely. Make sure to note their exact location so you know where to take them for repair when you're done.
After you’ve located your damaged, broken, or leaky sprinkler heads, it’s time to determine whether you should repair or replace them. If the sprinkler head is simply misaligned and not damaged, then realigning it will be enough; however, if the head is cracked or otherwise damaged beyond repair, then replacing it with a new one is likely the better option. Make sure to take all necessary measurements for the new replacement head before heading out to buy the part!
4. Clean Any Obstructions from the Sprinkler System.
It is important to ensure the entire sprinkler system is free of any dirt, debris, and obstructions that may be clogging it up. In some cases, the obstructions can simply be removed by hand. However, if necessary, you can use a power washer or garden hose with enough pressure to break through any tougher blockages in the system or in the joints connecting pipes.
5. Prime the Sprinkler System for Testing with Water Pressure Gauge.
After the clogs and other potential issues have been addressed, it’s time to prime the sprinkler system for testing. This is best done with a water pressure gage. A typical home lawn sprinkler system should operate between 35-45 psi. If you find the pressure is either too low or too high for your needs, you can then adjust accordingly to find the
best balance that works best.
