Refill Paint Sprayer Reservoir

What happens here

After the initial spraying, the painter proceeds to refill the paint cup of the handheld sprayer. He pours paint from a larger 5-gallon bucket directly into the sprayer's cup, being careful not to overfill it. Once the cup is adequately filled, he securely reattaches it to the sprayer unit, ensuring a tight seal to prevent leaks during operation.

Goal: Ensure a continuous supply of paint for the spraying process.
