The Wavin HepVO Hygienic Self Sealing Waste Valve replaces the traditional water-seal trap and prevents the escape of foul sewer air from waste discharge systems. The unique HepVO waterless trap from Wavin won't dry out due to siphonage, evaporation or movement, and because there is no water, it won't leak, gurgle or crack due to freezing temperatures. This valve can be installed vertically or horizontally, and is ideal in places where space is to a minimum.

• No siphonage, no noise
• Prevents foul smells escaping the drainage system
• Can be installed vertically or horizontally
• Ideal in tighter applications
