McAlpine Basin Space Saver with Self-Closing Waste Valve

McAlpine Basin Space Saver with Self-Closing Waste Valve

The McAlpine Basin Space Saver with Self-Closing Waste Valve is designed to maximise storage space beneath your basin while ensuring efficient and hygienic waste management. Its compact design allows for full use of under-basin cabinets or furniture, while the self-closing membrane opens automatically under water pressure to allow free discharge and then seals shut to prevent foul odours or gases from entering the room. The valve also draws in air to balance negative pressure, eliminating the need for secondary ventilation and offering greater flexibility in plumbing design. Easy to maintain, it can be cleaned without dismantling the pipework by simply removing the split pin and rinsing the membrane in warm soapy water. With no traditional water seal, it won’t dry out from evaporation or disuse, ensuring reliable, long-term performance.
