Backwater valve

Multitube

The high-performance solution for larger pipes.

The Multitube is a powerful backwater valve for large-diameter pipes in public,

municipal and industrial areas. It can be installed in an exposed drainage pipe.

The Multitube is also completely corrosion free as it is made entirely from

polymer. Available in diameters of Ø 260 mm to Ø 515 mm.

Area of application

The Multitube backwater valve is suitable for use in leaching and pond systems

and behind cisterns that are separately connected to a rainwater channel or that

lead to a drainage ditch. It provides not only reliable protection against backwater,

but also provides additional protection against rats, mice, frogs and vermin.
