Repairing a Punctured Polyethylene Irrigation Line

Quick Fix for a Cut Poly Pipe

If you've punctured the black polyethylene (poly) lateral line, repair it with insert fittings and hose clamps.

Step-by-Step

1. Expose ~12" of pipe on each side of the break.
2. Cut out the damaged section cleanly.
3. Slide a stainless steel hose clamp onto each cut end.
4. Insert a barbed coupling (same size as pipe, usually ½", ¾", or 1") into both ends.
5. Center the coupling, slide clamps over barbs, and tighten securely.
6. Turn on water and check for leaks.

Notes

• Use NSF-rated clamps and fittings for potable/irrigation use.
• For mainline (constant pressure), consider compression fittings or glued PVC for a more permanent repair.
• If the pipe is old and brittle, replace a longer section.
