Test Faucet Functionality

What happens here

Finally, turn the hot and cold water supply valves back on by turning them counter-clockwise. Slowly open them all the way. Test the faucet by operating the handle to check for leaks around the stem and to confirm a steady, improved water flow from the aerator. If any leaks or issues persist, re-check the installation of the components.

Goal: Verify the faucet is working correctly with no leaks and proper water flow.
