for the same reason the inspector's test for a wet system does not have to be located at the physically farthest from the flow switch- i.e., in a closed hydraulic system, pressure (change) is transmitted instantaneously to all parts of the system. with an expansion chamber, you happen to have a little 'play' in the closed aspect, ~.13369 ft3

Only a very small part of the piping is exposed to temperature extremes. If anti freeze expands only when temperature extremes are encountered, why size a tank for the whole system that sits in in conditioned or heated air? Just curious!
