Pressure Tank Volume Control

The tank contains a supply of water for household use along with a pocket of air.

Pressure tank volume control.

If you convert from a non bladder type water pressure tank to a water tank using an internal bladder part of that installation will include the removal of any air volume control valves on the system including an avc that may be mounted on the well pump above ground jet pumps or a hidden avc that is found inside the well piping submersible. The tank s steel shell supports the water weight to ensure water never sits in loose fitting vinyl or rubber bags that can fold crease and wear. The more modern style has a rubber bladder or diaphragm inside that separates the air chamber from the water chamber. 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.

An 80 gallon size tank only holds 23 gallons of water and a 20 gallon size tank only holds 5 35 gallons of water. 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 old style tank is just an empty galvanized tank that is equipped with an air volume control that keeps the tank charged with air. There are basically two types of pressure tanks which are hydro pneumatic and bladder or captive air tanks. 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. How a well water pressure tank works.

As water fills the tank the air is compressed and when it reaches a certain preset level the well pump shuts off. Types of tanks and total tank volume.
