Does anyone know where I can purchase this part? It has split as it is made of plastic and home depot does not carry the replacement. I only need the donut part, I have the tube to connect to the overflow. Thank you

I have the same problem, did you findone?

Since his post has not been answered for 6 months I don't think so. Give me all the information you can, Brand named, model numbers, etc. And a picture would help a lot, Back to you, Tom

I know what he is talking about, Tom. Drstukatl, you will need to contact Dupont directly @ 800-906-7765 (call Monday-Friday).

They should be able to help you find a replacement donut. You will NOT find these available at any stores.
