The pressure is assumed to be 18bars at the outlet point. A major disadvantage with the break tank is that it is a pressure-neutral tank that absorbs the pressure coming from the public supply, removing any potential inlet pressure. Other factors such as the tank inlet flow rate and the usage patterns of the building should also be taken into account - buildings with a poor rate of mains water supply will require .

A siphon break is provided at the top of the seal to avoid siphoning the whole tank content to the drain. This pressure bleeder will (like all of them) will fill your master cylinder up to the very top. For one vendor the minimum set pressure is 0.07 barg (1 psig, 28" WC) which may require a higher tank design pressure resulting in a more expensive tank.
