Self-Closing Waste Valve 1.5″

Self-closing polypropylene 1.5″ waste valve – 153mm long
BSP female inlet nut x universal compression outlet.
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.
Can be fitted in horizontal or vertical position.
Can be fitted where a non-return valve can be of benefit to the plumbing installation.
No water seal so it can never dry out through evaporation or lack of use – the membrance remains sealed.
Not recommended for use with shower trays unless there is access for maintenance.
