HepvO® self-sealing waste valve prevents the escape of foul sewer air from waste discharge systems, and maintains pressure equilibrium in soil and waste installations.
Uses a purpose designed silicone rubber membrane membrane to create an airtight seal between the living space and the drainage system.
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.
Space saving in-line design makes HepvO easy to install in confined spaces, like pedestals, shower units, baths and under kitchen sinks. Hep?O can be installed vertically or horizontally by using the 90° adaptor.
HepvO is available in 1 ¼” and 1 ½” dimensions. HepvO joints are compression type. Running adaptors and knuckle bends are available as part of the system.
