I have a laundry sink made of what looks like concrete in my basement. The house is about 50 years old, I don't know if the sink itself is that old.
Under the sink, there is an small extension where the drains are located. This is the rusty-looking thing at the top of the picture in the URL below.
There is some kind of bushing which is screwed into this extension into which the drain pipe is inserted that prevents water from running onto the floor (this is the white thing on the left of the pipe at the top).
This bushing, which I think is made of rubber, is deteriorating and has broken off on the right side of the pipe, so that water is running out from a crack between the drain pipe and the extension under the sink -- not a lot, but enough to be annoying.
Does anyone know if this bushing is some part which is still available? I have checked a few online sites for information, and can't find anything...
