Sprinkler Drip Supply Line Repair: A Comprehensive Guide

Water leaking out of a half inch drip line

Identifying the Damage

This image shows a sprinkler drip supply line that was broken by the blade of a tiller. Such accidents can cause significant water loss and reduced irrigation efficiency.

Assessing the Damage

The tiller has sliced cleanly through the line, creating a cut about 3 inches long. Without repair, the drip line will not function properly, leading to uneven watering and potential plant stress.

Cutting out a damaged section of drip line with PVC cutters

Step 1: Remove Damaged Section

Using PVC cutters, remove the damaged area from the existing line. While this repair is small, you can replace entire sections using the same method if necessary.

Step 2: Prepare Repair Piece

Create a repair piece using two barbed half-inch couplings and a new section of drip line. Insert the barbed couplings into each end of the new piece.

Inserting a repair piece into the broken drip line

Step 3: Insert Repair Piece

Begin inserting the repair piece into the broken drip line. You may need to work the pipe and fitting side to side while pushing them together for a secure fit.

Step 4: Secure the Connection

Continue pressing the fittings in until the pipe meets the collar on the fitting. This ensures a tight, leak-free connection.

Step 5: Test the Repair

After completing the repair, test the fitting to ensure it holds and that there are no leaks. These fittings don't require clamps since the pressure in the drip line should be below 40 PSI. However, if you experience persistent leaks, consider using clamps for added security.
