One of the most challenging aspects of dealing with a shower cartridge leak behind the wall is identifying it. Here are some signs that may indicate a leak behind the wall:

1. Water stains on the ceiling or walls: If you notice water stains or discoloration on the ceiling or walls near the shower, it could be a sign of a leak behind the wall.
2. Musty smell: A persistent musty smell in the bathroom may indicate the presence of mold or mildew, which can be caused by water damage.
3. Sound of dripping water: If you hear the sound of dripping water even when the shower is not in use, it could be a sign of a leak behind the wall.
