How to Replace Sprinkler Heads Like a Pro

Before learning how to replace sprinkler heads, you should assess them to ensure that replacing the heads is the right fix and that there’s not some other sprinkler system repair you need.

Make Sure You Need a New Sprinkler Head

Here are some signs that you need to replace your sprinkler head: 

• The sprinkler is not spraying evenly or at all.

• There are visible cracks or broken components.

• Water is leaking from the base of the sprinkler.

• The head doesn’t rise properly when activated.

• You notice water pooling around the head even when it’s off.

Choose the Right Sprinkler Head

Sprinkler heads vary based on water pressure, spray patterns, and the type of lawn or garden they serve. Check the existing sprinkler head’s model number or take it to a local home improvement store to find a suitable replacement.

Turn off your water at the sprinkler shut-off valve. Then, it’s time to dig:

1. Use a shovel or trowel to carefully dig a circular hole around the sprinkler head. Aim for a radius of 2 inches.

2. Dig 4 to 5 inches deep, ensuring you don’t damage the underground piping.

3. Keep the removed grass and soil intact so that you can replace it later. You might find it helpful to set the grass on a piece of plastic or a small tarp.

4. If the soil is loose, gently compact the sides of the hole to prevent it from collapsing while you work. You can also pour a cup of water onto the top of the sprinkler head before removing it to help the soil compact itself a bit.

Now that you’ve exposed the sprinkler head, you can remove it:

1. Grip the base of the sprinkler head and gently twist it counterclockwise.

2. If it’s stuck, use pliers or an adjustable wrench to loosen it.

3. Once it’s loose, carefully pull the entire sprinkler head, including the shell, out of the ground.

4. Inspect the connecting pipe for debris or damage before proceeding.

With the old head removed, you can install the new one:

1. If you want to, you can wrap the threads of the new sprinkler head with plumber’s tape to prevent leaks, but this isn’t a requirement.

2. Align the new sprinkler head with the existing pipe and screw it in clockwise by hand.

3. Once snug, use pliers or an adjustable wrench to tighten the head, but avoid over-tightening.

4. Adjust the sprinkler head to ensure it’s level with the ground.

If your sprinkler head requires a nozzle, attach the correct size and adjust it to control the spray pattern.

Before calling it a day, make sure your new sprinkler head is working correctly:

1. Turn on the sprinkler system and watch the new head do its thing.

2. Check for leaks around the base.

3. Ensure the spray pattern covers the entire area you need to water, and adjust it as needed.

If the sprinkler isn’t performing like you think it should, recheck the nozzle size and alignment.

With the new head installed, you can put your lawn back in order:

1. Refill the hole with the removed soil, gently tamping it down to eliminate air pockets.

2. Place the grass or sod back over the hole, pressing it down firmly.

3. Water the area to help the grass settle and encourage regrowth.
