Q: I have leaks where the ¼” fitting has been inserted into the larger mainline
A: The leaks may be caused from irregular shaped holes or improperly seated barbed fittings. Sometimes a gentle tug on the barbed fitting will snug it up against the tubing wall. If this does not fix the leak then you may remove the dripper or fitting and insert the large end of a goof plug in the hole and you can then punch a new hole nearby.
Please note: If the hole is too large for a goof plug to fix, the section would need to be cut out and then coupled together with a tubing coupler. Please see videos on item pages.
