Frequently folks call and ask us how big the HepvO waterless P-trap is.

 HepvO complete kit

  The HepvO can be installed both vertically or horizontally.

 

If you are not familiar, The HepVo Waterless Valve replaces the old P Trap with a short tube and internal diaphragm that prevents backflow of air and water into showers and sinks.

The water inlet pipe side of the HepvO uses industry standard thin wall pipe. The output side of the HepvO adapts to both thin wall or sch. 40 or 80 drain waste 1.5″ ABS/PVC piping.

The HepvO® is certified to meet the requirements of ASME/ANSI A112.18.8 and can be installed in new homes and industrial buildings by having the building inspector use the “Alternate Materials section” of the Building Code. HepvO® can also be used to fix existing plumbing systems by replacing p-traps which are suffering from odor or noise.

While the HepvO® is relatively new to the North American market  it is not a new product. It has been in high volume production in the UK since 1997 and it is widely used in Europe, Australia and the Far East. It has attained numerous international approvals against very demanding standards and has achieved an enviable track record of trouble-free performance. There are over 2 million installations worldwide.
