Is HepvO used in addition to a conventional trap?
No, unlike other products that prevent foul odors entering the living space, HepvO is used instead of a convetional water-seal trap.
What are the dimensions of the HepvO valve?

Will I still need to install auxilary venting on waste pipe branches?
No, HepvO acts as a highly effective local air admittance device, removing the need for secondary venting.
Can I use acidic drain cleaning chemicals?
HepvO is resistant to standard caustic-based drain cleaners. It is also resistant to acid-based cleaners with concentrations up to 10%. When flushing with higher concentrations of acid-based cleaner, the valve must be removed before the operation. After any maintenance, it is recommended that the valve is flushed through with clean water.
Do I still need to connect each fixture on its own dedicated waste branch?
No. HepvO prevents induced siphonage between adjacent fixture traps so it is now possible to make multiple connections on the same branch. This can save yards of tubing or piping and gives great flexibility for locating fixtures and designing waste systems.
HepvO is a new product to me - how can I be confident that it will give a good installed performance?
HepvO is relatively new to the North American market but 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 5 million installations worldwide including more than 1 million in North America.
Will HepvO promote better hygiene by stopping the escape of foul sewer air into habitable spaces?
Yes. The valve has been proven to perform under conditions in which traditional water seal traps are vulnerable to failure. It will continue to perform under back pressures 10 times greater than those experienced in correctly designed soil and waste systems.
Does the air tight seal break down if a strand of cloth or hair collects in the strainer and falls down between the faces of the valve?
No. HepvO has undergone extensive foreign body testing (including IAPMO IGC203-04 and ASME/ANSI A112.18.8). Tests show that the valve will maintain an air tight seal around an obstruction such as hair, fabric, strands or spaghetti.
What is the life expectancy of the HepvO Valve?
Installed correctly can be expected to have a life expectancy at least equivalent to current water sealed traps. In addition HepvO is guaranteed against defects in materials or manufacturing for a period of 3 years.
Will HepvO block easily for example if fat is discharged through it?
No. Extensive testing has shown that is less prone to blockage than traditional water seal traps. Note: because the ‘straight through’ design of HepvO it does not trap debris discharged through the waste fixture care should be taken with jewelry and other valuables.
Will the seal be maintained even when the fixture hasn’t been used for some time?
Yes. HepvO does not depend on a water seal and so it will continue to maintain a seal. Even if a fixture never gets used or is used very infrequently.
Does the HepvO valve make a noise?
Under normal conditions HepvO operates silently, unlike normal traps that are prone to ‘gurgle’.
Will HepvO support microbiological growth?
No. The materials used to manufacture HepvO will not support microbiological growth, for example, of mold and mildew.

I see the HepvO can be used on a bidet, so can I install one on my toilet as well?
HepvO can be installed on a bidet and any other bathroom / kitchen application where a 1 ¼” or 1 ½” tubular p-trap is normally used. HepvO is not suitable for use on toilets which have a 4” trap built in as part of the complete fixture.
