## Overview

The BV1B/UA Hepvo Waterless Waste Valve is a stainless steel, self-sealing valve that replaces traditional water traps by preventing sewer odors and gurgling noises without relying on water seals. Its innovative membrane design resists evaporation, siphonage, and freezing, ensuring reliable, low-maintenance performance in both vertical and horizontal installations.

## Description

HepvO is a self sealing valve designed to close the waste connection below a sanitary fixture to prevent the escape of foul sewer air into the dwelling. HepvO is the innovative hygienic Self Sealing Waste Valve. It replaces the traditional water-seal trap and prevents the escape of foul sewer air from waste discharge systems. Unlike conventional waste traps, HepvO does not rely on trapped water to create a 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 depletion or freezing. 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. This means that secondary venting of the waste system via the inclusion of air admittance valves in the waste system is no longer necessary.

## Questions & Answers

**Q: Can this be used in under a normal vanity in a house?**
A: Yes. That's exactly where I used it due to space constraints. Couldn't fit a normal P- trap.  Works great.

**Q: Will this equalize grey tank pressure like a vent? Building campervan and can’t easily vent tank outside.**
A: All this is a trap for your shower or sink, not a vent. It is like P trap under your sink or shower to keep odors coming back up sink.  I used one under my shower where I have no room for a P-trap.

**Q: are the adapters shown in picture included?**
A: yes

**Q: Does this have a check valve inside or what method does it use to prevent backflow? What does the interior look like and how much pressure is needed?**
A: Yes, it a check valve, there is a soft tube inside that goes flat and stops on back flow.
