I bought this product when I guess and redid my downstairs bathroom. The first model I had installed, there was a problem with the pull to drop the drain plug. When I called in to find a fix as the drain plug had broken the rest of the way. They sent me a revised model with a push down drain plug that does not need attaching to any other pieces. This is just a quick click down took engage it and push it again to open the drain.

I love this faucet assembly!!!!!
