Initial Water Turn-On & Leak Check (at stem)

What happens here

With the new stem and packing nut securely installed, it's time to check for leaks. Go back to the angle stop valve under the sink and slowly turn the hot water supply back on. Carefully observe the faucet stem area for any signs of dripping or leakage. If there are no leaks, the stem replacement was successful in stopping the drip. Turn the water supply back off at the angle stop valve before proceeding to the next step.

Goal: Verify the new stem prevents leaks at the faucet body.
