What is Backflow Testing?

In a typical plumbing system, pressure is maintained in order to keep clean water flowing into a home. When these pipes freeze, begin to leak, or fail in any way it often leads to backflow. Backflow testing is a sewer repair service that is conducted to detect water contaminants that could be harmful to people. It is also critical to ensure the system is in working condition.
