A supply line can release water into a cabinet, utility room, ceiling cavity, or wall. Water may then move along framing, insulation, subfloors, and other connected materials. It can appear in a different room from the original pipe break.
For example, a pipe above a kitchen ceiling may wet the ceiling surface first, then affect insulation and framing. Water can also run down a wall and collect beneath flooring. Drying only the visible stain may leave moisture behind.
The extent of damage depends on the type of pipe, how much water escaped, how quickly the flow stopped, and which materials became wet. No online description can determine the condition of a particular home. An on-site assessment is needed.
