a. Accumulator tank / pressure tank contains a factory charged air cushion. This is usually 10% the rest fills with water.

b. When the pump starts, water enters the accumulator reservoir. At maximum pressure the system is filled. The pump then shuts off.

c. When water is demanded at the tap / outlet, pressure in the air chamber forces water into the system. The pump stays off until the water in the pressure tank has emptied or till minimum pressure is reached, then the pump starts and runs until pressure is reached. Therefore the pump doesn't necessarily turn on each time you demand water at the outlet.

The pressure tank will absorb excess pressure in your system before it reaches your pump and causes damage. Therefore protecting the life of the pump and the pump pressure switch.
