How to Connect a Zinc Ring to a Pipe Under the Sink

The metal flange, directly underneath your sink, is a metal ring that is attached to the drain pipes. This ring is commonly made of zinc, but can also be made of other types of metal. If you notice that the ring is rusted or cracked, then you can replace it with a zinc ring part. Connecting the ring is a simple process, and a new zinc ring can be purchased from a home improvement store or online retailer.
