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.
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!
Awesome product! I’ve told several people about it.
I installed one in my kitchen sink and one in my bathroom sink, both of which are in my rv certified tiny house.
Using the Hepvo waterless P trap has allowed me to eliminate vents to the roof of my RV. The Hepvo streamlined the plumping and allowed us to take advantage of otherwise useless space. No sewer odors from the p trap that has lost water letting orders into the RV. I no longer have to worry about having antifreeze in my p trip during the winter. I highly recommend Hepvo.
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 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.
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 breech in the water seal barrier.
No limescale
The flexibility of the HepvO valve seal prevents the accumulation of limescale.
Easy flow
HepvO allows discharge water to pass easily through, regardless of the volume.
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. It subsequently closes to reseal the waste system and prevent foul air release. This means that the venting of the waste system is improved. 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!
Performs 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.
Copes with Food Waste
HepvO continues to perform when fats, solid foodstuffs, and other household materials are rinsed down the drain.
