Your home’s plumbing system is pretty large and pretty complicated, but there are two main lines that make the whole system work: the main water line, which brings in the potable water, and the sewer (or septic) line that removes all the waste water. When there’s an issue with either of these lines, your plumbing system will develop problems.

So if you have a sewer line problem, how are you going to know about it? Here are some tips from our Carney Plumbing Heating & Cooling experts.
