Polypropylene check valve Clapet OZO

Protection against backflow flooding from rainwater (RW)(1) networks in public, private and industrial infrastructures is apriority and a necessity. On existing networks, the installation of flap check valves may be limited by: • difficult access to the installation; • the absence of water fall (a culvert, etc.); • a sloping or uneven surface that prevents surface- mounted installations (damaged surface, etc.). For these and all other configurations,OZO® is the ideal solution, because it can be installed inside the pipe itself, whateverthe material, in the networks RW networks(1). Quick and easy to install, it provides optimum protection for homes and buildings against flooding. Unpleasant odours from the sewer system are also confined to the pipe thanks to the check valve's innovative, patented membrane.
