MOST HOME OWNERS ARE NOT AWARE that the main sewer line can become clogged over the years. This clog can be due to normal blockages from everyday use or roots working there way into the pipe through small cracks or openings in the connections of where the pipes meet. Whatever the reason behind the clog, there is no question that a blocked sewer line is going to cause problems. The sewer line is what transports waste from the home to the city sewer system, so resolving the problem should be done as quickly as possible.
