McAlpine Basin Space Saver with Self-Closing Waste Valve
1.25 inch BSP female inlet nut x 1.25 inch universal compression outlet
Designed to allow full use of storage space below the basin within the cabinet or furniture as overall height is only 62 mm
The 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
The valve allows air to be drawn into the discharge waste pipe when negative pressures occur and eliminates the need for secondary ventilation to the discharge pipework
The valve can be easily cleaned without having to disassemble the discharge pipework. Simply remove the split pin at the front of the valve, take out the plug and membrane and clean in hot soapy water
The Wash Hand Basin (WHB) self-cleaning waste valve having no water seal can never dry out through evaporation or lack of use of the basin as the membrane seal remains closed
