Stop unpleasant odours escaping into your living space with the HepVo Waste Non-Return Valve 32mm. 

The hygienic self sealing waste valve is made for closing your waste connection below a sanitary appliance. It aims to reduce negative pressure within the waste system as it opens and brings in fresh air until a pressure equilibrium is reached.

The valve is efficient without impacting performance and risking foul air escaping from the drain or sewer.
