Check valve that reduces the risk of backflow of surface water.
Dimensions Ø110-Ø200 are installed in most sinks. Easy installation.
Can be easily removed from ground level using the aluminum rod and handle – without having to go down into the well.
The check valve consists of a self-closing flap and is delivered with a sleeve. The aluminum bar is 140 cm, but can be joined if needed.
The check valve is made of age- and corrosion-resistant material, PP (polypropylene). The flap has a rubber gasket and is made of chrome-nickel material to prevent the intrusion of rodents.
