Re-Connect P-Trap and Test for Leaks

What happens here

With the new drain flange securely installed, re-connect the P-trap and any other drain pipes that were previously removed. Ensure all slip nuts are hand-tightened first, then give them a slight snug with channel locks if necessary, being careful not to overtighten plastic nuts. Once all connections are made, run water into the sink. Observe all connection points carefully for any signs of leaks. Check around the drain flange, the P-trap connections, and any other re-attached pipes. If any leaks are observed, tighten the corresponding nut slightly until the leak stops.

Goal: Complete the drain connection and verify the absence of leaks.
