HepVO Sanitary Waste Valve

The P-Trap Alternative!

Wavin offers a complete solution in combination with Bow’s ABS pipe and fittings.

Wavin’s HepvO is available in 3.18cm (1-1/4”) and 3.81cm (1-1/2”) dimensions, and can be installed vertically or horizontally, thanks to an angled adapter. For sewer pipes with low, intermittent or seasonal use, Wavin’s HepvO is an effective alternative to conventional p-traps. Already used in North America in recreational vehicles and boats, Wavin’s HepvO technology is approved for use in residential and commercial units by the 2024 Uniform Plumbing and Mechanical Codes for HVAC applications.

Frequently Asked Questions

is Wavin HepVO used in addition to a conventional trap?

NO, unlike other products which prevent foul odors entering the living space, HepvO is used instead of a conventional water-seal trap.

When using a Wavin HepVO in place of a P-trap in a residential or commercial building what should I do about venting?

The full venting requirements of the applicable Plumbing Code shall still be followed, irrespective of whether a P-trap or a Wavin HepvO is installed.

Can I use drain cleaning chemicals?

Wavin HepvO is resistant to standard caustic-based drain cleaners. It is also resistant to acid-based cleaners with concentrations up to 10%. When flushing with higher concentrations of acid based cleaner, the valve must be removed before the operation. After any maintenance, it is recommended that the valve is flushed through with clean water.

Wavin HepVO is a new product to me - how can I be confident that it will provide good performance once installed? 

Wavin HepvO is new to the North American market, but it is not a new product. It has been in volume production in the UK since 1997 and it is widely used in Europe, Australia and the Far East. It has attained numerous international approvals against very demanding standards and has achieved an enviable track record of trouble-free performance.

Will Wavin HepVO promote better hygiene by stopping the escape of foul sewer air into habitable spaces?

YES - The valve has been proven to perform under conditions in which traditional water seal traps are vulnerable to failure. It will continue to perform under back pressures 10 times greater than those experienced in correctly designed soil and waste systems.

Does the airtight seal break down if a strand of cloth or hair collects in the strainer and falls down between the faces of the valve?

NO – Wavin HepvO has undergone extensive foreign body testing (ASME A112.18.8). Tests show that the valve will maintain an airtight seal around an obstruction such as hair, fabric strands or spaghetti.

What is the life expectancy of Wavin HepVO?

Installed correctly can be expected to have a life expectancy at least equivalent to current water sealed traps. In addition, Wavin HepvO is guaranteed against defects in materials or manufacturing for a period of 3 years.

Will Wavin HepVO block easily for example if fat is discharged through it?

NO - Extensive testing has shown that Wavin HepvO is less prone to blockage than traditional water seal traps. Note: because the ‘straight through’ design of Wavin HepvO does not trap debris discharged through the waste fixture care should be taken with jewelry and other valuables.

Will the seal be maintained even when the fixture hasn’t been used for some time?

YES - Wavin HepvO does not depend on a water seal and so it will continue to maintain a seal whether a fixture never gets used or is used very infrequently.

Does the valve make a noise?

Under normal conditions Wavin HepvO operates silently, unlike normal traps that are prone to ‘gurgle’.

Will Wavin HepVO support microbiological growth?

NO - The materials used to manufacture Wavin HepvO will not support microbiological growth, for example mold and mildew.

Building healthy and sustainable environments

Safe and Efficient

Future generations face a 40% shortfall between water supply and demand. Alongside other experts, Wavin is working to deliver safe and clean water security through enhanced rainwater reuse, the digitalization of water management and more secure and durable piping.

Sanitation and Hygiene

Outdated sewer systems are overwhelmed by a triple whammy of urbanization, population growth and climate change. We are working towards a healthier future with long-lasting sanitation solutions that deliver greater capacity, fewer leaks, less clogging and better monitoring. 

Climate Resilient Cities

Smarter systems are needed to meet the five big challenges our cities face: floods, droughts, heat stress, ground water depletion and surface-water pollution. From roof to river, we are helping with connected water capture, attenuation, cleaning, reuse, and transportation solutions to make cities climate resilient. 

Building Performance

Constrained by time, cost, and product sourcing challenges, many of today’s buildings fail to deliver on their expected performance. Through improved digital modelling, we can help our partners predict time and resource needs throughout the building process and provide intelligent solutions for better urban living.
