Hello all, would greatly appreciate any help with this frustrating issue. Bought our house 2 years ago, it was built in the 40s. Late 2022 had a couple of pinhole leaks, one after another, in the old 108ft copper water main. On the advice of our plumber, replaced the entire water main with new copper and protective sleeve in Jan 2023 as it was presumably at the end of its service life. Fast forward to March 2023, we had pinhole leak in the new main line. Plumber was puzzled, repaired it under warranty. We have since had 2 more pinhole leaks, also repaired under warranty. Thats a total of 3 leaks in a 4 month old copper line. The leaks are in the straight copper pipe, not at the joints. I have sent off soil for testing and will send water as well. Yesterday I found out that 4 other neighbors in very close proximity have all had water main leaks since January, a few of them have had more than multiple leaks. Presumably most of them still have an old copper line, but still. What is going on here? (Photo attached is of the leaks in the new copper at 3 months)
