Detecting a pipe leak behind your wall can be tricky, as many signs are subtle and may go unnoticed until significant damage occurs. Look for unusual dampness, mold growth, or water stains on your walls or ceilings. Additionally, changes in your water bill or the sound of running water when no taps are on can indicate a hidden leak. It's essential to consider factors like the age of your plumbing and the materials used, as these can affect leak susceptibility.
