Wavin HepvO: Self-sealing Waste Valve for Waterless Drainage

HEPVO

HYGIENIC SELF-SEALING WASTE VALVE

HepvO, manufactured by Mexichem Wavin, is a unique self-sealing waste valve that prevents the escape of foul sewer air from waste discharge systems, and actively maintains the pressure equilibrium in soil and waste installations. As a dry sealing valve, HepvO utilises 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 an appliance emptying, and closes to form a tight seal after the appliance has discharged under normal atmospheric conditions.

KEY FEATURES AND BENEFITS

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 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 re-entering your home in situations where water seals are weak.
Greater design flexibility - designers don’t have to work to safety margins required to avoid the possible loss of a water seal.
