Drainage installation for positioning on floor tile has opening for waste water and three parts which can be positioned against one another so as the alter the position of inflow opening

摘要

Drainage installation has an upper inflow opening (10) into which waste water enters, a first part (2) pre-assembled on the floor, a second part (3) whose position when assembled either influences or determines the position of the inflow opening. The second part, when at least partly assembled on the floor, can be moved against the first so as to alter the position of the inflow opening. The installation has a third part (4) which can be tilted against the vertical, so that the second part can be moved against the first.
