I'm sure it is 'well defined' someplace in the sales literature, but since most of us live in the real world, it makes absolutely no sense at all. i have from 47 to 120 gallon xtrols, and there is no logic when you look at a tank that says 47 gallons and your mind pictures a tank the size of a 55 gallon barrel......and you say 'NO F......Way! The 120's are even more dramatic...... If you shut down a 120 gallon tank, you'd be hard pressed to get 30 gallons out of the pressure bladder side of the thing.
Thought you'd luv to hear more confusion about 'equivalent storage'.
I am learning a lot, your right the tank only holds about 1/4 of the rated size.
