Disassemble and Empty the P-Trap

What happens here

Place a bucket, or a makeshift container like a bag-lined box, directly beneath the P-trap to catch any standing water and debris. The P-trap is the U-shaped pipe under the sink. It typically has large plastic nuts at both ends connecting it to the tailpiece (from the sink) and the wall drain pipe. Loosen these nuts by turning them counter-clockwise. While often hand-tight, if they are stiff, use channel locks or specialized plumbing pliers (like 'Knipex Cobras' as shown in the video). Once the nuts are loose, carefully detach the P-trap and empty its contents into the collection container. The video demonstrates the P-trap being heavily clogged, showing a narrow passage of only about 3/8 inch remaining.

Goal: Remove the P-trap to clear major blockages
