Hello Friends,
The flange in a kitchen sink is the visible portion of the drain system that connects the sink to the plumbing. It can become scratched or discolored, and the metallic finishes can sometimes begin to peel off the base metal. When there's a leak under the sink, it's possible that the flange has cracked, come loose or lost its seal. Fortunately, replacing the flange is a simple repair.
Thanks and Regards
