HepVO is a unique waterless 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.
When you need to prevent foul sewer gases from entering a building, HepVO valve can be installed as an alternative to a conventional plumbing water trap.
As a dry-sealing valve, HepVO uses 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.
Watch our overview video to find out more about how HepVO works.
Traditional water traps can sometimes lose their seal due to evaporation, siphonage, leaking or movement, but since HepVO doesn’t rely on water to create a seal, it doesn’t carry these risks of failure.
It also offers a great range of other benefits for both installers and end-users:
HepvO is suitable for use on sanitary appliances and can also be installed on discharge pipework from unvented domestic hot water systems and condensate lines from boilers and air conditioning units. Click here to find out more
