Remove Old Leaky Drain Assembly

What happens here

Begin by loosening the nuts that secure the old drain assembly. Use a screwdriver to create a split or break the seal on the main nut under the sink. Then, use channel locks or a basin wrench to fully loosen and remove the nut. Once the nut is removed, carefully separate the drain assembly from the sink. Be prepared for some water or debris to fall, especially if the drain has been leaking. Remove the entire old drain body and its connecting pipes.

Goal: Disassemble and remove the existing leaky sink drain.
