HEPVO

Waterless Drainage

HepvO is a unique self-sealing waste valve that prevents the escape of foul sewer air from waste water 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 while it is emptying, and closes to form a tight seal after the fixture has discharged under normal atmospheric conditions.

KEY FEATURES AND BENEFIT

Saves space - piping can be installed in a straight line or at a neat 90° angle from the fixture’s outlet.
Prevents odours escaping - the elastomeric one-way membrane of the valve opens to allow wastewater through then closes, forming a tight seal to stop odours from re-entering the room.
Hygienic - Because it’s water-free, the HepVO valve does not promote the build-up of waste materials which can cause bacteria.
Tested and approved - rigorously tested for most conditions. HepVO carries the Watermark Licence WMKT20062.
Reliable and effective - prevents sewer gases from re-entering your home in situations where water seals are weak.
Greater design flexibility - designers don’t have to work to the safety margins required to avoid the possible loss of a water seal.
