Description
The Wavin Osma HepVO BV1 WH WH is a 32mm waterless self sealing waste valve in white polypropylene. Rather than relying on a water seal, it stops foul sewage gases escaping into the living space and admits air into the pipe system, which also makes it suitable for branch pipe ventilation.
It suits domestic and light commercial installers and DIY buyers fitting washbasins, sinks and similar appliances where space under the unit is tight. Its slimline design and connection options make it practical for both new installations and replacements.
