Our house has a twenty gallon pressure tank operating off the well pump. We have a generator to run the pump as well as other things.
We went with multiple redundancies in our water plan. We live in Florida and without AC we’ll need a lot of water. Water supply isnt a problem for us, only making it fit to drink. In hurricanes we’ve gone through a case of water very quickly.
I have the same (maybe 15, it’s the diaphragm pressure tank). At any rate, you might be interested in a hand pump that works in unison with your well pump in case your run out of fuel for the generator or the generator just decides to quit.
I was checking out this one of these types myself:
