Down-feed? IPC 606.1

[steveray]

606.1 Location of full-open valves. Full-open valves shall be installed in the following locations:
5. On the top of every water down-feed pipe in occupancies other than one- and two-family residential occupancies.

commentary speaks of vertical pipes "through one or more stories"....In a single story, multi tenant building. Do you guys require valves on all "drops"?......For example, each exam room in a doctors office.....? Or is the intent multi story only?

Thanks!

Saw that one MT, but it is not what the commentary shows or speaks of.....Commentary shows a vertical riser with "drops" down to specific areas....But only shows multistory even though the language in the commentary references single story....

Designer option, most are only going to provide one main valve for shutoff for water supply to that tenant on that floor.

This is a good question that deserves some thought.

No for a single story. Yes for more than one story.
