@HU-330341168 - I was the one who said I was mystified, so thanks for that explanation. However, there are some things you wrote that need clarification and correction. When you decide to replace your sink as you mentioned, please keep these things in mind: First, the issue in this thread appears to be the flat bottom of a sink that is not sloped properly - that can occur in a farmhouse sink or in an undermount sink if either is not made well.
