Sewer Backup Prevention

It is not uncommon during heavy rainstorms for municipal sanitary sewers to become overloaded with more volume than they can handle, and the result is sewer backup into basements and other low lying drains in that area. Large quantities of sewage contaminated water can be pushed through floor drains, toilets or showers and can create a potentially dangerous and unhealthy environment in your home.
