Flooding can sometimes cause sewage from sanitary sewer lines to back up into houses through drainpipes. These backups not only cause damage that is difficult and costly to repair, but they also create health hazards. A good way to protect against sewage backups is to install backwater backflow valves, which are designed to block flow into the house
There are two types of check valves:
The Backwater Valve must be installed on each drain line plumbing fixtures located below the street level (Basement).
The Main Backwater Valve is installed on the main sewer of a building.
