Today I used this waste sink in my (belonging to the apartment) and thus sent the 8 year old, completely rotted cheap copies with completely rusted rods closure mechanism in the hunting grounds. The dismantling of the old thing was more complicated than the installation of this new push-up closure. There was due to the enclosed seals partly derogatory reviews - which I can not or only partially to join. Sure, the attached seals are suitable for sealing rather for very shallow drain holes in tanks. In my case - it is probably many times - the sink in the area of the drain hole is round-conical shaped, ie, as formed with bevel the porcelain material. Here the flat seals do not work, you need a wedge-shaped seals above and below the Ausgußlochs. Taking into this and is preparing with the purchase of such seals before, the absolute well-fitting, perfectly sealed installation is done in minutes. The material of the waste is also contrary to other voice here not too thin, despite above existing hexagon pulling the lower part of the set only with the strength of their own hand, then you can also nix of the seals (conical!) Are squeezed. I recommend this waste so with a minimal obstacle to using the enclosed seal, and would buy again at any time!
