How to Repair a Broken Sprinkler Pipe

July 19, 2010 at 12:02 pm | Category: Remodeling Contractor

Step 1
Turn off the water supply to your sprinkler system. This can usually be done by turning off the water supply to the house at the city meter. Contact the city water department if you are unfamiliar with how this is done. If you have a separate meter or a well, there should be a cutoff valve located near your sprinkler control box.
Step 2
Clear out the area around the broken section so that you have room to work. Make sure you have adequate room to saw if necessary.
Step 3
Cut the pipe on both sides of the leak, approximately 2 to 3 inches from the leak. Remove the broken pipe section.
Step 4
Measure the broken piece and cut a replacement section from the new pipe. Compare your new pipe to make sure that it will fit into the gap. Dry fit the connector sleeves onto the new section and install it on the existing pipe to verify the fit.
Step 5
If everything looks good, take the new pipe section apart and coat all pipe ends and the inside of the connectors with PVC primer. Let dry completely.
Step 6
Once the primer has dried, apply a coat of PVC glue to the inside of the connectors and the outside of the pipe ends. Assemble the new pipe by installing the connectors to the new section and then installing the new section in the gap left in the existing pipe. Push the sections together to ensure a tight fit. You will want to work quickly, as the glue dries in a short amount of time.
Step 7
Allow the glue to dry according to the directions on the package. This is usually a couple of hours, and is a very important step. If you turn on the water before the glue has time to set, the water pressure could cause the new section to come apart.
Step 8
Once the new section is completely dry, turn on the water and check for leaks.
