Head Pressure is a basic concept in plumbing that refers to the force of water in pipes based on height and gravity. Think of it like water pressure in a tall building - the higher up you go, the less pressure you have. Plumbers need to understand head pressure to properly design and fix water systems, especially in tall buildings or homes with multiple floors. It's similar to understanding water flow and pressure requirements, which are essential for making sure sinks, showers, and appliances work correctly.
