Ignored the little pool of water at first, but when pink mold began growing around the drain, decided I needed to do something about it. The problem has to be related to the finish Delta put on this fixture. I have installed other Delta fixtures and never had this problem before. Sent a note to Delta about it but haven't heard back yet. This site is much faster

. Hoping to come up with some way to improve the surface wetting characteristics of the drain flange without destroying the finish. May be impossible.
