Hrm. I have not had good luck with plumbers. This is a 2 inch copper pipe leaking in the wet wall between the men and women’s locker rooms at the 2 year old pool. I had to crawl into a tiny crawlspace and shimmy 20 feet to get to this spot. We put a temporary cover over the leak. How exactly some certified plumber is going to get in there I will love to see. Hopefully this is under warranty – this should have been caught during pressure testing. who knows how long it has been leaking.
