VIVA 40mm Magna Self-Sealing Waste Valve | 1½” Waterless Trap | WTSTC40

VIVA 40mm Magna Self-Sealing Waste Valve

The VIVA 40mm Magna self-sealing waste valve is a 1½” waterless trap designed for waste pipe installations where a compact, self-closing trap solution is needed. Instead of relying on a standing water seal, the Magna valve uses an internal membrane which opens when water is discharged and then closes again to help prevent foul smells and sewer gases entering the building.

This VIVA WTSTC40 self-sealing waste valve is suitable for installation under sinks, basins, bidets, baths and urinals. It can be installed in a horizontal or vertical position, making it useful where space is limited or where a traditional trap is difficult to fit.
