What is the difference between a freshwater leak and a sewer leak?
A. Freshwater or, supply lines carry water to fixtures such as faucets and sinks while sewer or drain lines carry waste water away from fixtures. A general rule of thumb is that if the leak is fresh water it will leak at a constant rate regardless of whether or not a fixture is in use and will have no odor while a sewer leak will leak only while a fixture is in use and will generally be accompanied by an unpleasant odor.
