This seems a little weird, as my expansion tank, takes overflow from the swirl pot via a pressure release cap. If the cap reaches a certain PSI, then it releases and dumps water into the expansion tank. Why can I not have the just dump to the ground?
My expansion tank does not feed back into the system... well, it doesn't seem too...
Thoughts?

I would say you could do what you are proposing, but finding another solution for a catch tank would be the best solution. There is plenty of room in that side of the wheelhouse.

If you routinely overflow the pressure tank, and it doesn't refill from the expansion tank, then your pressure tank cap may be faulty / wrong. Get a Stant #11230 cap. That is the proper cap.
