The underwriters often have their own preferences so in his book, the refill rate might not be a consideration. So it’s back to the owner to decide if the legally adopted code allowance for including the refill rate is good enough for him while understanding that it gives the insurer some heartburn. Let them hash it out and come back to you with a decision on how to proceed.
Apparently if the system is that close, way back when no one considered Fire Flow requirements from the Fire Code. Has the local Fire Code official rendered an opinion on the matter? I would want his buy-in as well. Craig L.

I just thought that it was always an acceptable practice. The situation is I have a new owner of a warehouse with an existing ground tank and pump house. We will be replacing the pump. The tank is only 3000 gallons short of the largest system demand plus the outside hose times the duration requirement. The city supply to the tank will be more than able to make up the difference. The underwriter is saying that the “reliable automatic refill” cannot be considered. I was wanting to show proof that it was acceptable prior to the 2013 edition.
