Keep nasty odours out of the bathroom with this self-sealing waste valve by Viva. The adaptable 32 mm waste valve can be used for basins, baths, bidets, urinals and sinks, and it can be installed under the fittings in either a horizontal or a vertical position. It's also ideal for places where space is limited like walk-in showers. 
The non-return valve has an internal membrane. It opens to release wastewater then automatically closes, preventing foul smells and sewer gases from coming into the building. Because it's a waterless trap, it won't give off any unpleasant gurgling noises.
The valve comes complete with a 90° inlet and straight compression adapters for quick and easy installation. Because it works both horizontally and vertically, there is no loss of flow wherever it's installed. Please note that drain cleaning products must not be used with this valve.
• Prevents foul smells and sewer gases entering the building
• Can be installed in a horizontal or vertical position
• Complete with 90° inlet and straight compression adapters
