25 years ago, they used a certain type of pipe, and it gets pin hole leaks when lightning strikes nearby. They didn't discover this for 20 years and now everyone who has a 25 year old house is having to replumb all the pipes. The old pipes are no longer to code.
The plumbers did fix the leak last year, but this leak is a couple of inches away from the previous leak. So it's not the plumber's fault. We should have replumbed last year when we had the first leak, but we were hoping it wouldn't happen again so soon. If this is the second leak, then we probably have leaks all over, and I don't want any more surprises.
It's always something.
