Hepvo is an innovative hygienic Self Sealing Waste Valve. It replaces the traditional water-seal trap and prevents the escape of foul sewer air from waste discharge systems.

Unlike conventional waste traps, Hepvo does not rely on trapped water to create a seal, instead, HepVo uses a self sealing membrane which performs the same function as a water seal trap but without the risk of depletion or freezing. Hepvo actively eliminates negative pressure within the waste system by opening and allowing in fresh air until a state of equilibrium with atmosphere is reached. This means that secondary venting of the waste system via the inclusion of air admittance valves in the waste system is no longer necessary.
