HepᵥO System Overview
The HepᵥO valve delivers all the benefits of a traditional water trap—without the common drawbacks.
Reliable, Hassle-Free Performance
Conventional water traps can fail over time due to:
- Evaporation
- Siphonage
- Leaks
- Movement or displacement
HepᵥO eliminates these issues by using a self-sealing elastomeric membrane. This innovative design performs the same function as a water trap but without the risk of losing the seal—ensuring long-lasting protection against foul sewer gases.
