Allow the water to run for about 2 minutes before you check the lines. Do this in the daytime, where you’ll have an easier time spotting the leak.
You may not be able to find the leak just by listening, but it can help you narrow down your search.
If the sprinkler line is exposed enough for you to see water spraying out of a break or crack, check the line for a visible crack, and use a marker to mark the location of the leak.
Place an item like a shovel or a rock on the ground near the leak.
The break or leak in the water line will be located between the last working sprinkler head and the first nonworking one.
Wait 1-2 minutes to allow the water to finish flowing through the system. Be sure to shut the valve completely so there isn’t water flowing through the line when you make your repairs.
A larger break in the system could mean a costly repair.
Cut a square or rectangular shape so it’s easier to fit back into place when you’re finished.
Cut the roots with the hand trowel if they cling to the ground, but be sure to leave enough so they can regrow.
Make the whole wide enough so the pipe is exposed for 6 inches (15 cm) on each side. Dig about 3 inches (7. 6 cm) below the line so it’s easier to remove. Pile the dirt you remove next to the hole so you can replace it when you’re finished.
Remove the damaged piece of pipe after you cut it.
You can find band clamps at your local hardware store, department stores, or online.
Bring the damaged section of pipe to the hardware store so you can get a slip coupling with a diameter that fits into it. Use a slip coupling with a 1 inch (2. 5 cm) slip. You can find a slip coupling at a hardware store or online. Extend the coupling as far as it will go into the pipe.
Use a screwdriver to tighten the band clamps.
Allow the system to run for 5 minutes so you can be sure the coupling and clamps won’t come loose.
