Bath Space Savers with Self-Closing Waste Valve

WV-1: Bath Space-saver. 1½” BSP female inlet nut x 1½” universal compression outlet

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. This allows for greater flexibility in the plumbing design

The valve can be easily cleaned without having to disassemble the discharge pipework. Simply remove the cover at the front of the valve, take out the plug and membrane and clean in hot soapy water.

WV-1 self-cleaning waste valves have no water seal, so can never dry out through evaporation or lack of use, as the membrane seal remains closed

WV-1 Overall height 75mm

NOTE WV-1 is not recommended for installation on kitchen or utility sinks.
