Which non-return valve do I need for my Fekabox?
The Fekabox has a 50mm (2") outlet. Therefore you need a 2" ball check valve.
The outlet of the pump might be smaller, but all the pipes and connections in the Fekabox are already included, so you need a valve that fits with the Fekabox' outlet.
How should I install the Fekabox?
The Fekabox is a pre-mounted system that can be installed directly. They need no regulations, and are ideal for the collection and processing of contaminated waste water in the house from basements that are situated below the level of the sewer system. The Fekabox must not be used for disposal of flammable or explosive liquids such as gasoline, diesel, gas oil, fuel oil, solvents etc.
