Where you need to prevent foul sewer gases from entering a building, HepvO can be installed as an alternative to conventional water traps. HepvO is suitable for use on sanitary appliances (e.g. wash hand basins, kitchen sinks, showers), and can also be installed on discharge pipework from un-vented domestic hot water systems and condensate lines from boilers and air-conditioning units. HepᵥO is widely exported around Europe and the rest of the world to countries such as US, Australia and Japan. HepᵥO currently holds a number of product approvals in those countries in which it is sold. The innovative nature of the HepᵥO waterless valve makes is suitable for use as a problem solver, for instance in hot countries where water traps are prone to drying out or in recreational vehicles, where water traps are prone to losing their seal.

As house design becomes more complex, and as more and more buildings are converted into flats, there is greater potential for pressure fluctuations to occur in plumbing systems. Read more here.
How it works
HepvO is different to traditional water traps as it uses a soft silicone rubber membrane to create a seal, instead of “trapped” water. HepvO can be installed vertically or horizontally.
HepvO is available in 1 ¼” and 1 ½” dimensions. HepvO joints are compression type. Running adaptors and knuckle bends are available as part of the system.

HepvO & chemical cleaners
Strong acids, e.g. cleaners containing high concentrations of sulphuric acid, must not be used on HepvO. When rodding or flushing with a sulphuric acid solution, the valve must be removed before the operation. HepvO is resistant to standard caustic-based drain cleaners.
