Changing a sprinkler head is a relatively simple DIY task that can save you money on lawn care. Here's how you can do it, with options for replacing the entire unit or just the internal components:
1. Replacing the Entire Sprinkler Unit
This is often the easiest option, especially if the entire sprinkler body is damaged.
- Turn off the Water: Locate the sprinkler's water supply valve and shut it off to prevent flooding.
- Unscrew the Old Sprinkler Head: Using your hands or appropriate tools (like adjustable pliers or a sprinkler wrench), carefully unscrew the broken sprinkler head by turning it counterclockwise.
- Inspect the Riser: Check the riser (the pipe that connects the sprinkler head to the underground plumbing) for any damage or debris. Clean or repair it as needed.
- Apply Plumber's Tape: Wrap the threads of the riser with Teflon tape (plumber's tape) in a clockwise direction, applying two to three layers. This creates a watertight seal.
- Screw on the New Sprinkler Head: Screw the new sprinkler head onto the riser, turning it clockwise until it's snug but not overly tight.
- Turn on the Water and Test: Slowly turn the water supply back on and check for leaks. Adjust the sprinkler head's spray pattern and distance as needed.
2. Replacing Only the Internal Components
If the sprinkler body is in good condition, you can replace only the internal components (nozzle, strainer, etc.).
- Turn off the Water: Shut off the water supply to the sprinkler system.
- Unscrew the Sprinkler Head: Unscrew the broken sprinkler head from its casing.
- Open the Casing: Carefully open the top of the existing sprinkler casing. This might involve releasing clips or unscrewing a small component.
- Remove Old Components: Take out the old and broken internal components (e.g., the nozzle, filter screen, and any other parts). Note their positions for easy replacement.
- Install New Components: Slide the new internal components into the casing, ensuring they are properly seated and aligned.
- Reassemble the Sprinkler Head: Reattach the sprinkler head to the casing, tightening it securely.
- Turn on the Water and Test: Turn the water back on and inspect the sprinkler for proper operation, adjusting the spray pattern and distance as necessary.
Tips for Success:
- Matching the Sprinkler Head: Make sure to buy a replacement sprinkler head that is compatible with your existing system (same brand, type, and spray pattern).
- Proper Tools: Using the correct tools will make the job easier and prevent damage to the sprinkler system.
- Avoid Over-Tightening: Over-tightening can damage the threads and cause leaks.
- Flushing the System: Before installing a new sprinkler head, briefly turn on the water to flush out any debris in the pipes.
- Consider a Sprinkler Wrench: A sprinkler wrench is specifically designed for removing and installing sprinkler heads and can be helpful, especially for tight spaces or corroded fittings.
