HepvO is a unique self-sealing waste valve that prevents the escape of foul sewer air from waste discharge systems, and actively maintains the pressure equilibrium in soil and waste installations.

As a dry sealing valve, HepvO utilizes a purpose designed membrane to create an airtight seal between the living space and the drainage system. The self-sealing valve opens under the water pressure of a fixture emptying and closes to form a tight seal after the fixture has discharged under normal atmospheric conditions.

HepvO is not affected by siphonage and will therefore not allow the escape of foul air into the living space from the drain or sewer.

The HepvO valves promotes hygiene, particularly where a fixture is infrequently used. HepvO differs from conventional traps, which can dry out or hold water which can become stagnant causing the emission of smells and enhancing bacterial growth.

HepvO allows the placement of a greater number of fixtures together on fewer discharge pipes without compromising performance of the sanitary discharge system.

HepvO operates silently and is not subject to “gurgling” noises typically associated with siphonage and indicative of a breech in the water seal barrier.
