A method for at least partial installation in a floor or a room of a drainage arrangement, comprising the steps of:

• providing a drainage body (2) with an opening (9), through which water is drainable, the drainage body (2) having on its top side a groove (8),
• providing a flexible sealing film (3),
• connecting a connecting portion with the sealing film (3) and with a portion of the drainage arrangement, wherein the connecting portion comprises a seal (6) and a support (5) which supports the seal (6), the connecting portion and the flexible sealing film (3) have an opening (4) defined therethrough through which waste water is passable, wherein the connecting portion and sealing film (3) comprise a sealing device (1) arranged at least partially above the drainage body (2), so that water that has passed through the opening (4) of the sealing film (3) is receivable in the opening (9) of the drainage body (2),
• connecting the seal (6) to the support (5) before attaching the sealing device (1) to the drainage arrangement,
• inserting at least in portions the support (5) together with the seal (6) arranged circumferentially about the opening (9) in the drainage body (2) into the groove (8),
• snapping in place in the groove (8) or clipping into the groove (8) the support (5) together with the seal (6).
