I agree, I’m just trying to find where it was allowed in earlier editions.

If your demand is 1000 gpm for 60 min and your city supply can do 500 gpm, then you just store 500 gpm for 60 min. I'm out on the road so I can't look up the exact reference. But the good thing is you don't need crazy formulae with a hundred exponents to figure this out. It's just simple math.

I have researched earlier editions but I have not been able to find where the reliable automatic refill has been previously allowed; however, I recall this being the case. Am I overlooking something?
