Reassemble the P-trap and Check for Leaks

What happens here

Once the item is retrieved, carefully reattach the P-trap to the drainpipe by aligning the ends and sliding it back into place. Hand-tighten the plastic coupling nuts back onto the pipe connections. Ensure they are snug enough to prevent leaks, but avoid overtightening, which could damage the plastic threads or seals. After reassembly, turn on the sink faucet briefly and check for any drips or leaks around the connections of the P-trap. The narrator confirms that checking the P-trap is always a good first step when something is lost down the drain.

Goal: Restore the sink's plumbing to a functional, leak-free state.
