Elements for a perfect installation

Non-return single or dual plate valve

Climate change and the increasing urbanization of land can cause overload problems in sewer networks with the consequent risk of flooding.
To prevent such risks it is necessary to install non-return single or dual plate valves. The valve is installed outside the house, along with a trap, and positioned inside a gully for an easy inspection. It is made of a resistant ABS and is available in diameters 110 to 200 mm.

The trap should be installed together with a nonreturn valve positioned inside a gully. The dual cap allows for simple access and cleaning.
