Measure & Cut Tailpiece Extension

What happens here

Take the new P-trap assembly and loosely fit it to the new Tee fitting installed in the wall, ensuring the P-trap is oriented correctly (the curve facing downwards). Hold the P-trap's horizontal arm level or with a slight downward pitch towards the wall. Measure the distance from the vertical sink tailpiece down to where it will connect with the P-trap. Also, measure the distance from the sink tailpiece to the trap for a potential extension. Cut the appropriate extension tube or a section of pipe to this measured length using a PVC pipe cutter. Ensure cuts are straight and clean.

Goal: Accurately measure the required length for the sink tailpiece extension and cut the new pipe to size.
