I had the exact issue that Jan described in a review where the days after I installed, water leaks out of the cold water top. Looks like they would replace part/all of it but not for weeks. So, I’m now going through the frustrating tasks of dissembling, and trying to replace I rings to see if we can get to be better when we have guests coming in a couple of days. The sink is beautiful and seems high quality but not so sure now.
