How to Replace a Sprinkler Head

Irrigation is the lifeblood of a healthy lawn, yet sprinkler heads are frequently the first components to fail under the pressure of foot traffic and lawn mowers. A broken or clogged head not only wastes water but leaves brown patches where your grass needs it most. Fixing this is a straightforward maintenance task that saves you a costly service call. Done well, a replacement ensures the nozzle spray pattern matches the rest of your zone and sits flush with the soil to prevent future damage. You are essentially resetting the system to its peak efficiency, ensuring even distribution across your lawn. It is a quick win that keeps your landscaping vibrant and your water usage in check.

1. Cut and expose the head. Carefully cut a circle in the turf around the sprinkler head using a hand trowel or spade. Remove the sod in one piece so you can replace it later, then dig down until you reach the base of the head where it connects to the riser pipe.
2. Clear debris and threads. Clear away the loose dirt and debris from around the base of the head. This prevents grit from falling into the riser pipe when you unscrew the damaged unit.
3. Unscrew the broken head. Grip the body of the sprinkler firmly and twist it counter-clockwise to unscrew it from the riser pipe. If it is stuck, use a pair of channel-lock pliers, but be careful not to crush the plastic pipe.
4. Flush out trapped debris. Briefly turn on the sprinkler zone to allow water to spray out of the riser. This clears any rocks or debris that might have fallen into the line during the removal process.
5. Thread on the new head. Thread the new sprinkler head onto the riser by hand until it is snug. Ensure it is perfectly vertical so the spray pattern covers the intended area correctly.
6. Test and restore the lawn. Turn the system back on to check for leaks and confirm the spray pattern is correct. Once verified, backfill the hole with dirt and replace the sod you removed earlier.
