What is the purpose of a well system pressure tank and how does it contribute to the overall functioning of a well system?

The purpose of a well system pressure tank is to regulate the water pressure in a well system. It helps maintain a consistent water pressure throughout the system by storing water under pressure. This contributes to the overall functioning of the well system by reducing the frequency of the pump turning on and off, which can extend the life of the pump and provide a more consistent water flow to the household.
