I'd be inclined to go for used-defined tags. The existing tags do not
accurately describe the feature, and are at best misleading. A suggestion:
As far as capacity is concerned, I'd opt for the standard unit for
measuring large water volumes - megalitres (ML).
1 ML = 1000 cubic metres exactly.
In my experience, large water tanks are never stored under pressure.
Rather, the water surface is at atmospheric pressure, and the position
of the tank on a hill provides any pressure to taps below it. So the
lack of pressure is a given.
A large tank under pressure could be a dangerous thing.
