Signs a hidden pipe problem needs attention
A pressure change, damp wall, growing water stain or visible leaking connection deserves a closer look. Other warning signs include unexplained water use and the sound of running water while fixtures are off. These clues help frame an inspection, but none identifies a specific failed pipe on its own.
Note where the change appears and whether it is persistent. Tell us about earlier repairs near the same area and whether more than one part of the home is affected. A stain shows where moisture became visible; it does not by itself establish the source or the full extent of the problem.
