Turning is not good...the drain and especially the pop-up arm nor the seals. I'm not a pro, nor have I installed one. I'd seriously consider resetting it with some silicon under it. You could probably mask and wipe any that oozed out to maintain a clean look, but that would probably stop it. I'm picturing this as a sink thatsits above (mostly) the vanity. If I don't have the right idea, or to help others maybe consider posting a picture (manage attachments under the submit reply boxes).
