We had a pin hole leak in a line over the kitchen cabinets a while back. Plumber
blamed copper from China. Said a small imperfection in the pipe can cause a
buildup of minerals and eventually eat through the copper. Said it would start
as a small drip taking a long time to drop. The leak could have started years
before I noticed the wet sheet rock in the bathroom adjoining the kitchen.
Cost USAA over $26,000. Plumber cost me $100 to fix the leak.
