The packing on the washbasin's kelep (the part that moves up and down for drainage) has gone bad. I bought a replacement at a home center, but I got the wrong size and couldn't use it. I opened the package once, so it's "like new," but it hasn't come into contact with any of the washbasin parts in use. I measured it carefully, but since I'm an amateur, please refrain from purchasing if you require perfect accuracy. Immediate purchase is OK.
