What is the click-clack plug ?

The click-clack plug is installed in the washbasin plughole without the need to connect it to the fitting. The name comes from the click sound at the moment of opening and shutting the water outflow. The method of operation is very simple. To shut the plug hole you just push the cap of the plug and it gets locked in a “shut” position. If you push the cap again, the plug locks out and the plug hole is opened. Thanks to its simple construction and a special nut, the BISK plug is universal and fits all types of washbasins (with or without drainage) and all types of fittings, both with or without the hole for a leverage in the back of the washbasin body.
