Step 1: The Materials for the Job

The first step of any DIY plumbing renovation is gathering the materials and tools you need to handle the task at hand; this applies to broken sprinkler head repair, just as it does for replacing a faucet or installing a new shower head.

Step 2: Clearing the Area and Accessing the Sprinkler

With shovel or trowel in hand, start careful digging around the sprinkler head in question. When digging, leave enough room for your hands to reach the entire sprinkler head unit, as well as the riser (the pipe segment connecting the head to the irrigation line). You should only have to dig around 6-8” to access the whole sprinkler unit.

Step 3: Removing the Sprinkler or Line

Now that you have access to your sprinkler and irrigation line riser, determine whether the task requires replacing just the sprinkler unit, or the irrigation line as well. If the irrigation line is severely broken or faulty, you may want to contact a plumbing specialist to deal with the problem.

Step 4: Replace the Sprinkler Head and Riser

For sprinklers without pop-up head features, you may have to cut out the riser connecting your sprinkler to the irrigation system (this is where that trusty handsaw or pipe cutter comes into play). Attach a threaded tee fitting to the existing pipe, and a male coupler onto the tee fitting once it’s in place.

Step 5: Filling in the Gap

Once the glue has hardened, you can refill the initial hole and attach the spray nozzle to your replacement sprinkler head. Make sure the dirt is compact, to keep the new sprinkler in place and level with other units.
