Introducing HepvO
The World’s Most Amazing Waterless Drain Waste Valve
Introducing HepvO
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.

The HepvO sanitary waste valve opens under the water pressure of a fixture emptying and closes to form a tight seal after the fixture has discharged.
Horizontal installation
Installed at any angle other than vertically, the HepvO must have ‘ribs down’ to ensure correct drainage, using the supplied angled adapter.
The benefits of HepvO
The World’s Most Amazing Waterless Drain Waste Valve
No foul odors
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.

Hygienic
The HepvO valve 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.

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

No "gurgling" noises
HepvO operates silently and is not subject to "gurgling" noises typically associated with siphonage and indicative of a breach in the water seal barrier.

No limescale
The flexibility of the HepvO valve seal prevents the accumulation of limescale.

Perfect for occasional use
Perfect to solve problems in existing failing systems and on applications where fixtures are only used occasionally, such as RV's, guest bathrooms, holiday homes, boats and mobile homes.

Improves venting to negative pressure
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. In many cases, on an RV for example, the inclusion of a branch air admittance valve is no longer necessary.

Different climates
HepvO is the perfect solution for hot and cold conditions. In Arizona, (a hot, snowbird destination), the water in P-traps evaporates, causing a horrible smell. Not with HepvO!
See all product detailsPerforms under back pressures
The HepvO valve will perform under back pressures which are ten times greater than those experienced in a typical soil and waste system.

HepvO continues to perform when fats, solid foodstuffs, and other household materials are rinsed down the drain.

I've had a HepvO valve installed in my Airstream for several years and it is great! No risk of freezing and I didn't have to sacrifice any headroom in the shower. I couldn't be happier.
Installed valve in bathroom sink, no more odor just like advertised. Great product!
The Hepvo valve is just what we needed for the tricky plumbing in our remodeled bathroom. It has been working great for the past year. Very happy with it.
