Remove Old Brass Drain Pipes

What happens here

Place a bucket underneath the P-trap to catch any residual water or debris. Use a plumbing wrench (channel locks) to loosen the slip nuts connecting the P-trap to the sink basket strainers and the wall drain. Fully remove the P-trap assembly and any horizontal brass pipes.

Goal: This step involves carefully disassembling and removing the old brass drain lines, including the P-trap and associated piping, from under the sink.
