Sewage Backups: Common Causes, Prevention and Cleanup Arguably one of the most unsavoury things a homeowner may have the misfortune to endure is a sewage backup. A sewage backup can occur if there is a blockage or damage in the sewer line that obstructs the wastewater flowing from your home to the municipal sewer line on your property boundary.  The obstructed or restricted flow can cause wastewater flowing from the home to build up in the pipes and eventually back up, resulting in overflows at your drains, or in worst-case scenario water overflowing from the toilet bowl inside your home. Many aged sewer lines can also be damaged allowing large volumes of storm or rainwater to flow into the sewage line leading to the city sewer connection.  This large surge of water can certainly cause sewage backups into the home or basement of the home. As one can imagine, this can be very messy, rather smelly, and is generally not very pleasant and best avoided. The tips below will arm you with the knowledge to help you prevent a sewage backup in the first place, and also provide vital information on how to mop up should the proverbial... $%& hit the fan.
