ABSTRACT:
The overflow and drain fitting has a drain pipe (10), into which a closing plug (4), a float (3), as well as a mushroom-shaped plug (2) are inserted. The closing plug (4) can be lifted via bars (15), thus opening a partition (10b) between a riser channel (6b) and a return channel (6c) of a hidden riser pipe (6). With a sealing edge (2c) of a mushroom-shaped plug (2), the float (3) forms a check valve, which prevents water that may be contaminanted from returning into the basin (5). The closing plug (4), the float (3), and the mushroom-shaped plug (2) are loosely connected to each other via grasping arms (4b, 3b) and can be lifted out of the drain pipe (10) together as one unit to clean the fittings.
