How a well water pressure tank works. It is easy to install. Selecting the pressure tank total volume for typical systems will consider the tank draw down as compared to the pump capacity and required pump run time. The water worker 32 gal.

The three pressure switch settings for pressure tanks are 20 40 30 50 and 40 60. This air volume control ensures proper balance of air and water in a galvanized water tank. Water pressure or captive air tanks come in two different basic configurations. Tanks without air seal for pre charging will require an air volume control mounted on tank and connected to pipe tap marked a v c.

Types of tanks and total tank volume. The pressure switch setting is the pressure at which the pump turns on to fill the tank up and the pressure at which the pump shuts off knowing the tank is full. Pressurized well tank the water worker 32 gal. As water fills the tank the air is compressed and when it reaches a certain preset level the well pump shuts off.
