The Difference Between a Water Leak and Sewage Problems
Many people confuse a supply-network leak (clean water) with sewage problems, even though each has completely different signs.
Supply network leak
Usually continuous and pressurized because it comes from a network that operates under constant pressure, and its effect usually shows up as a higher bill before anything else.
Sewage problems
Usually associated with a clear bad odor, and the moisture typically appears only when the bathroom or kitchen is used, not continuously throughout the day.
Why does the distinction matter?
Because the inspection and repair approach differs completely between the two cases, and knowing the correct type saves you unnecessary time and cost.
