The SWEET-AIRE ODO-CHECK bag valve is designed to prevent the backflow of sewer gas into lateral sanitary sewage distribution lines. The prevention of the backflow of the sewage vapors eliminates the malodorous compounds from the main sewer from being forced back up the lateral line and ultimately discharged into the residence or industrial structure via the “p traps” or roof vents. Fabricated from reinforced, flexible PVC, the ODO-CHECK units are simple to install and provide a long service life.
