The number one complaint of RVers is holding tank odors coming into the inside of their RV. The HepvO is the innovative hygienic self sealing waste valve that replaces the traditional water-seal P-traps and prevents the escape of foul sewer air from waste discharge systems.
Unlike conventional waste traps — which work well in stationary houses, but have many drawbacks when used in RVs — the HepvO® does not rely on trapped water to create an odor seal.
Water seals are prone to failure by evaporation, siphonage, and other mechanisms. Instead, HepvO uses a self sealing membrane which performs the same function as a water seal trap but without the risk of the water seal evaporating or freezing.
HepvO actively eliminates negative pressure within the waste system by opening and allowing in fresh air until a state of equilibrium with the atmosphere is reached. This means that secondary venting of the waste system by the inclusion of air admittance valves in the waste system is no longer necessary.
The HepvO valve means enhanced plumbing design and system efficiency, without compromising performance or risking the escape of foul air into the living space from the drain or sewer.
The HepvO valve can be installed vertically or horizontally (with an adaptor) and is available in 1.5 and 1.25 sizes. This allows valuable space-saving installation options by providing additional under-sink storage space.
