Watch closely to see the spray from three pinhole leaks. Pinhole leaks are possible in new CIPP liners. Small, unseen pinhole leaks in the liner coating can cause minor infiltration. Pinhole leaks are normally the result from athe liner manufacturing process, not from the installers. Leaks can be repaired by chemical grouting or placement of a CIPP point repair.
