I recently installed a new vanity and purchased a faucet and push drain for them. They don't leak, and everything works well.
However, it appears as if the top of the drain in the basin isn't properly sized for the sink hole, or the sink hole has some issues. I'm not sure which is the issue as I researched both products and didn't find anyone discussing this issue.
Would a plumbing silicone around the edge solve for the standing water, or is this okay? You can see a slight gap on the drain.
