I could be wrong, but I think your “common feed and only one meter” is the “common water connection” referred to in the code section. So, it would still be an additional 5 gpm that you would account for through that section, not an additional 40 gpm.

That's a nice clarification in the '25 edition. Thank you very much Tom. So it sounds like if you have one connection for the whole townhome then 5gpm. Otherwise, in my case, bam bam bam x8 ..enjoy your 2" water meter. ;-) Thanks, AJ On Wed, Aug 7, 2024 at 2:11 PM Tom Wellen <[email protected]<mailto:[email protected]>> wrote: AJ, NFPA 13D, 2025 Edition A.6.5.2 The 5 gpm (20 L/min) provision is intended to be per connection and not per dwelling unit. A townhouse with more than two dwelling units fed by a common water connection would only require 5 gpm (20 L/min) to be added to size the common piping. Does this answer your question?

I have about eight being a townhome - each getting their own system but a common feed and only one meter. Should I include 5 gpm for ea unit or just 5 gpm for the whole lot?
