This Siebkorbventil and the Sanitop-Wingroth pipe trap "22225 9" are a perfect substitute for the siphon of Ikea sink. The set can be mounted quickly and easily. The only drawback was that the Siebkorbventil no Exploded was printed, but the pipe trap already. In our sink had to be cut during the assembly only the tube for the overflow. Nice extra is the operation of the plug on the Drehnopf. With the new siphon the water now flows off much better. Would buy the product at any time again.
