The Patented Preventer Plus Backup Prevention Valve
"Its Rough, its Tough, and its Always Ready"


The Preventer Plus is a uniquely designed fully equipped, precision balanced, float operated system. The preventer provides absolute protection against sewer back up and does it completely automatically. The Preventer is a heavy gage steel valve. It is completely galvanized and pre-threaded for longevity. All parts are non-corrosive consisting of neoprone and plexiglass for definite and precise closing. It is designed for years of trouble-free service and is backed by a warranty. At less than half the price of and overhead sewer, and the fact that all work is done outside of your home, we believe this is the flood prevention system of the future.
