Source of Leak Found!
When they told us the closet floor was wet, and they thought the leak was coming from under the concrete, we pictured them jack-hammering the beautiful concrete floor in long mazes like a gopher, across the room and down the hallway …
But hooray, the leak was in the closet wall. So they just need to patch up the pipe and repair the damage to the wall. Phew.
Will keep you posted!
