I have a friend who installed 184 feet of water line by joining 100 ft rolls of 3/4" polyethylene underground with the barbed joiners and hose clamps. He told me that initially it would not hold together after applying pressure and that each time he thinks he has it repaired, the joint fails within a few days. I have no experience with polyethylene, but I found a few threads on here that mentioned the technique of heating the pipe carefully to insert the barbed connector, installing two clamps (opposed) per side, the torquing them correctly after the pipe cools.
I have not seen the installation, but he told be he abraded the pipe to get more "tooth" in an effort to get more grip on the barbs. Could this be a problem? I am not sure if he was aware of the techniques described above. Any advice is greatly appreciated.
