It is an ideal plumbing solution which is cost effective and easy to install.
McAlpine self closing waste valve is manufactured from high-quality acrylonitrile butadiene styrene (abc) making it resistant to corrosive chemicals and physical impacts.
This equipment features a membrane that 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.
It has no water seal so it can never dry out through evaporation or lack of use of an appliance as the membrane remains sealed.
This valve can be fitted in both horizontal and vertical position.
It includes BSP female inlet nut x universal compression outlet.
Not recommended for use with shower trays unless there is access for maintenance.
