Sewer Back up Pros

Causes of Sewer Backup

•Blockages due to Tree Roots: Shrubs and trees seeking moisture can make their way into sewer line cracks causing extensive damage. They may start out small, getting into a small crack in the pipe; but as the tree or shrub continues to grow, so does the root. Tree roots can enter the service pipe at joints and cause blockages. They can also travel a long way, and roots from different types of trees act differently. If you suspect that city trees are responsible for sewer line damage, your plumber can contact the city and samples of the roots will be used to help identify the trees and who is responsible for cleanup. Sometimes a blockage is the result of a combination of city and private trees. In this case costs are split between the city and property owner.


•Sanitary Main: A blockage can occur in a city sanitary main. If the blockage is not detected in time, sewage from the main can back up into homes and businesses through floor drains. Usually this happens slowly, giving the owner time to call a licensed plumber to assess the damage. If water is entering your basement at a rapid rate, call the city public works office and report the problem immediately so that a city operator can investigate.


•Water in Basement: Most basement flooding is not related to the sanitary sewer system. In many cases, soil settles adjacent to the building and, if not corrected, leads to rainwater flowing towards the building and down the outside of the foundation wall. This is particularly true in older buildings where cracks may have developed in the foundation or floor slab which allow water to enter the basement. The cement floor and basement walls of these structures may have deteriorated to the point that they are no longer waterproof. Thus, water can show up in a basement which has never had a water problem. This frequently happens when the ground is saturated after repeated or heavy rain storms. Drainage can be improved by making sure that water drains away from the building. Homeowners can also prevent flooding by water-sealing the basement.
