Locate the damaged area.

The first step in repairing a sprinkler line is to locate the damaged area. This can be done by turning on the sprinkler system and observing where the water is leaking or spraying or were it is puddling up, usually the greenest part of your lawn.Once you have identified the damaged area, turn off the water supply to the sprinkler system to prevent further water waste and damage. It's important to note that if the damage is extensive or you are unsure of how to proceed, it may be best to call a professional for assistance.

Turn off the water supply.

Before beginning any repairs on your sprinkler line, it's important to turn off the water supply to the system. This will prevent any further water waste or damage while you work on the line. Locate the main shut-off valve for your sprinkler system and turn it off. If you are unsure of where the valve is located, consult your sprinkler system manual or "As-Built Diagram". If you don't have either contact a professional for assistance or try to find near the water meter. Now, you can shut off the water to just the irrigation by locating the shut off ball valve or you could shut it off at the backflow preventer. If you can't either then you will have to shut off at your water meter. Once the water supply is turned off, you can begin repairing the damaged area of the sprinkler line.

Dig around the damaged area.

Before you dig call your dial 811 to locate any utilities that might be buried in your yard. Once the water supply is turned off, use a shovel to carefully dig around the damaged area of the sprinkler line. Be sure to dig deep enough to expose the entire damaged section of the line. This will make it easier to work on and ensure that you don't accidentally damage any other parts of the line while making the repair. Be careful not to dig too close to the line, as this could cause further damage. Once you have dug around the damaged area, make sure to dig all the way around the pipe.

Cut out the damaged section.

Using a PVC pipe cutter or hacksaw, cut out the damaged section of the sprinkler line. Make sure to cut straight and clean edges on both sides of the damaged area. Measure the length of the removed section and purchase a replacement piece of pipe that is the same length. It's important to use the same type of pipe as the existing line, whether it's PVC, polyethylene, or another material. The easiest way to fix is using a slipfix or a PVC union which come all sizes. If your not sure what size you have. Take the piece of damaged pipe to your local hardware store and ask for help locating the part that is best for you. If you have to use PVC Pipe and couplings make sure to use PVC Primer and Cement.

Install a new section of pipe and fittings.

Once you have removed the damaged section of the sprinkler line, it's time to install a new section of pipe and fittings. make sure to clean both eands of the remaining pipe. Begin by applying PVC primer to the outside of the existing pipe and the inside of the coupling or slipfix. Then, apply PVC cement to both surfaces and quickly push the new pipe into place. Hold the pipe in place for a few seconds to allow the cement to set. Repeat this process for any additional fittings needed to connect the new pipe to the existing line. Make sure all fittings are tight and secure before turning the water back on.Before you backfill wait 15 minutes and turn the water back on and check for any leaks.

Hope this helps you tackle any sprinkler line breaks you may have been reluctant to repair. If you really don't feel comfortable taking on this project, please feel free too reach out to a Local Licensed Irrigation Professional.
