Test for Leaks and Smooth Movement

What happens here

With the spout reassembled and tightened, turn on the water supply to the sink. Check thoroughly for any leaks around the base of the faucet spout. Also, inspect the plumbing connections directly underneath the sink to ensure no water is dripping. Finally, test the movement of the faucet spout; it should now turn much more freely and smoothly. The video briefly shows the plumbing beneath the sink to confirm no leaks are visible there.

Goal: Turn on the water supply and test the faucet for any remaining leaks, checking both the spout area and the pipes underneath the sink. Also, verify that the spout rotates smoothly.
