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 to guarantee an easy inspection. It is made of a resistant ABS and is available in diameters 110 to 200 mm.
The range of traps with dual inspection cap is available in diameters from 110 to 400 mm.
The trap should be installed together with a non-return valve positioned inside a gully. The dual cap allows for simple access and cleaning.
The manholes allow the inspection of the sewer pipes in order to collect samples or to clean when necessary. The manholes in this range do not allow access to people.
The inspection chambers have a diameter of 1100 mm and an inlet from 640 mm allowing the access of qualified personnel for inspection.
The chamber contains steps as established by the standards to facilitate access; they are made of HDPE and are monoblock, they ensure a rapid and safe installation, as well as simple handling during transport.
Available in different heights, up to 5080 mm, they allow the inlet and outlet of pipes of different diameters. The larger diameter chambers are triple layer to guarantee greater resistance to pressure created by the surrounding earth.
