Reinstall Aerator and Test Flow

What happens here

Before reinstalling the cleaned aerator, always check for the presence and good condition of the small rubber gasket (O-ring) inside the aerator. This gasket is essential for creating a watertight seal and preventing leaks. If it's missing or damaged, replace it. Carefully place the gasket back into the aerator, then screw the aerator clockwise onto the faucet spout until it's hand-tight. Avoid over-tightening. If you needed pliers for removal, use them gently with a rag to prevent scratching the finish. Turn on the hot and cold water to test the flow. You should observe a significant improvement in water pressure and a steady, aerated stream.

Goal: Ensure the rubber gasket is properly seated in the aerator, then screw it back onto the faucet spout clockwise by hand. Turn on the water to confirm improved pressure and a steady stream.
