How can I extend a sink drain pipe to accommodate a longer distance or different layout in my plumbing system?

To extend a sink drain pipe for a longer distance or different layout in your Plumbing system, you can use a PVC extension pipe and fittings. Measure the distance needed, cut the extension pipe to size, and connect it to the existing drain pipe using appropriate fittings and PVC cement. Make sure to secure the connections properly to prevent leaks.
