Pressure tank
A diaphragm pressure tank is used on the discharge side of the pump to maintain pressure in the
pipes when there is no water demand. The unit stops the pump from continuing to run at zero
demand and reduce the size of the tank that is required for supply purposes.
The tank must be permitted and suitable for systems pressure.
