How Does a Sewer Backflow Valve Work?
Sewage backups are not only gross and inconvenient, they can cause thousands of dollars in damage in addition to creating health hazards for occupants in your home. All of this can easily be avoided, however, with the addition of a mainline sewer backflow valve to your plumbing system.
What causes sewage backup?
There are a variety of reasons for sewage backup. The main line that runs from your home to the sewer may become clogged due to grease, tree roots, and other blockages. In addition, water used in area homes as well as excess rain water can overwhelm the sewer system, causing water to back up in the lines and into your home.
