McAlpine WV-1 Space Saver with Self-Closing Waste Valve White 1 1/2"

Designed to allow full use of storage space below the basin within cabinet or furniture. Internal membrane opens under water pressure to allow discharge to flow freely and then closes to form a seal to prevent foul odour or sewer gas entering the building. Valve design eliminates the need for secondary ventilation to discharge pipework, allowing greater flexibility in plumbing design and can be easily cleaned without having to disassemble the discharge pipework. No water seal, so can never dry out through evaporation or lack of use, as the membrane seal remains closed. Not recommended for installation on kitchen or utility sinks. No Water Seal
