Identifying the Issue

This sprinkler was installed incorrectly, necessitating a lateral PVC pipe repair. The installer hard piped / glued the fitting for the sprinkler head. We always recommend using swing joints to prevent such issues.

Exposed broken Sprinkler PVC Pipe with Elbow ready for repair

Step 1: Expose the Lateral

Begin the repair process by carefully exposing the lateral pipe. This allows for better access to the damaged area.

Cutting out the damaged section of Sprinkler PVC Pipe

Step 2: Remove Damaged Section

Cut out the broken section of PVC pipe. If the break is too close to the elbow for a coupling repair, you'll need to remove the elbow as well.

Step 3: Assess the Damage

This example covers the removal of the sprinkler PVC pipe with elbow. A coupling repair would be a standard lateral repair, but removing the elbow provides more flexibility in the lateral line when assembling the repair.

Step 4: Prepare Replacement Parts

If possible, use the removed section as a guide for cutting your replacement PVC piping. This ensures a more accurate fit.

Assembling PVC pipe fittings for the repair

Step 5: Begin Assembly

Start building the repair toward the elbow. Use couplings or a tee with threads for attaching a swing joint to supply a sprinkler.

Step 8: Attach the Elbow

Apply glue to the PVC elbow and attach it to the repaired section. Ensure proper alignment before the glue sets.

Step 9: Secure the Connection

When gluing the PVC elbow, prep both sides simultaneously. Bend the longest lateral back to allow pushing the elbow on, then force it onto the short side. Once in position, hold it firmly until the glue sets.

Testing the repair by running the valve to check for leaks

Step 10: Test and Finish

If installing or replacing a sprinkler, assemble the swing joint and backfill. Test the repair after the appropriate drying time to ensure there are no leaks.
