Keeping your sprinkler system in good working order is one of the easiest ways to conserve water and maintain a healthy landscape. That’s why, through Resource Central’s Slow the Flow sprinkler evaluations and other water conservation programs, we share practical tips to help homeowners reduce water waste and keep their irrigation systems running efficiently.
A broken sprinkler head might seem like a small problem, but it can waste hundreds of gallons of water, leave dry patches in your lawn, and increase your water bill. Fortunately, replacing a sprinkler head is one of the easiest sprinkler repairs homeowners can tackle themselves.
Whether your sprinkler head has been damaged by a lawn mower, won’t rotate properly, or no longer pops up, this guide will walk you through the replacement process.
Signs You Need to Replace a Sprinkler Head
Before grabbing your tools, make sure the sprinkler head is actually the problem. Common signs include:
- Water spraying from anywhere besides the nozzle
- Water pooling around the sprinkler head
- The sprinkler head won’t pop up or retract
- Cracked or broken sprinkler housing
- Uneven watering or dry spots in your landscape
Replacing a damaged sprinkler head can restore even coverage and help your irrigation system operate more efficiently.
What You’ll Need
Before you begin, gather:
- Small shovel or a multipurpose gardening tool, like a hori hori knife
- Replacement sprinkler head
- Adapter (if needed)
- Bucket for removed soil and grass
- Garden gloves
How to Replace a Sprinkler Head
Step 1: Dig Around the Sprinkler Head
Carefully dig a few inches around the sprinkler head using a small shovel. Place the removed soil and grass into a bucket so it’s easy to refill the hole later.
Take care not to damage the lateral irrigation pipe beneath the surface.
Step 2: Remove the Old Sprinkler Head
Once you’ve exposed enough of the sprinkler assembly, unscrew the old sprinkler head from the riser or swing joint.
- Pro tip: Try to keep dirt out of the open pipe. If soil does get inside, briefly turn on that irrigation zone to flush it out before installing the new head.
Step 3: Check the Thread Size
Before installing your new sprinkler head, compare the inlet size to the old one.
Most residential sprinkler heads use either:
- 1/2-inch inlet
- 3/4-inch inlet
If the sizes don’t match, you’ll need an adapter before installing the replacement.
Step 4: Install an Adapter (If Needed)
If your replacement sprinkler head has a different inlet size, attach the appropriate adapter first.
For example, you may need a 3/4-inch to 1/2-inch adapter, which can typically be found in the plumbing section of most hardware stores.
Step 5: Install the New Sprinkler Head
Thread the new sprinkler head onto the riser or swing joint.
Before moving on, make sure:
- The head is snug but not overtightened.
- The top of the sprinkler sits flush with the soil.
- The sprinkler’s rotation stop (hard stop) is adjusted correctly according to the manufacturer’s instructions.
Step 6: Refill the Hole
Replace the soil and grass you removed earlier, gently pressing everything back into place with your foot.
The sprinkler head should remain level with the surrounding lawn.
Step 7: Test the Sprinkler
Turn on your irrigation zone and watch the new sprinkler head operate.
Check that:
- The sprinkler pops up properly.
- Water is covering the intended area.
- The spray arc and radius are adjusted correctly.
Make any final adjustments before moving on to the next zone.
Tips for a Successful Sprinkler Repair
- Replace broken heads quickly to prevent water waste.
- Match the new sprinkler head to the old model whenever possible.
- Avoid overtightening, which can damage plastic fittings.
- Keep sprinkler heads level with the surrounding soil to prevent mower damage.
- Run your irrigation system after every repair to confirm everything is working correctly.
