Stop The Leak In Your Kitchen Sink! Learn How To Replace The Drain Strainer
What happens here
Due to heavy corrosion, the retaining nut must be forcibly removed. Put on safety glasses. Use an oscillating tool with a metal-cutting blade to carefully cut a slot into the side of the nut, being cautious not to cut into the sink itself. Once a cut is made, use a flathead screwdriver to pry the nut open at the cut, breaking it free. Pliers can also be used to help break the weakened nut apart.
Goal: Remove the old basket strainer's retaining nut.
