Abstract: Sealing device (1) for sealing a drainage arrangement, including a flexible sealing film (3) with an opening (4), through which waste water can pass, and a connecting portion that is connected with the sealing foil (3) and that can be connected with a portion of the drainage arrangement.

Abstract: Drain component having a surface which in the installed state of the drain component may at least partially come in contact with one or several layers of a floor structure, wherein connecting means are at least partially arranged on the surface of the drain component for forming a connection to one or several layers of the floor structure. The drain component may include, for example, a tubular section (1) and a flange (2) protruding outwardly from the tubular section (1), wherein connecting elements (7) for the interlocking connection with a screed are arranged, for example, on the bottom side (6) of the flange (2), as viewed in the installed position.

Abstract: Drainage device for arrangement on a floor tile, the drainage device, when at least partially assembled in the floor, has at least two pipe lengths moveable relative to one another in such a way that a movement of the pipe lengths relative to one another allows an aperture in the floor tile and the upper inlet aperture of the drainage device to be made to coincide at least partially with one another. At the same time the pipe lengths have flanges extending radially outwards, which are sealed against one another by seals.

Abstract: A floor drain has at least a drain channel, a cover, and a fixing device for the releasable connection of the cover and the drain channel. The fixing device includes a latch connected with the cover and moveable with respect to the cover, and an element connected with the drain channel. The latch is adapted to come into releasable connection with the element connected with the drain channel. There is also described a method for installing and a method for de-installing such a floor drain.
