My house was just completely re-piped thru class action suit for the “gray” stuff. Now that the plumber has finished, I now have water on the outside of my shower and cabined near the shower plumbing. He is now saying that the shower pan is leaking and not due to his work. How can I test?? I had no leak before he started job. Can this be just a coincidence?
The simplest way is to call a different plumber and have the test for and verify if there is a leak in the plumbing supply line or the shower stall.
If the second plumber verifies the shower stall leak, you can use either plumber for the repair. If the second plumber finds the supply piping is leaking, call the first plumber back and have them repair it.
