The second cause of blockages is the presence of sand or roots entering the line through a break or other damage to the line. Tree roots will seek out sources of water, such as sewer lines, and will enter even the smallest cracks in the line. Roots will inevitably clog a sewer line. Larger cracks will not only allow roots to enter, but will cause sand and dirt to enter the line, blocking the flow. As dirt flows into the line, a small "sink hole" or depression appears in the ground above the leak. These sink holes almost always indicate a problem with a sanitary sewer line or a storm drain, and therefore should be investigated or reported.
