That's a good idea. If it doesn't cost too much in the way of bulk pipe I may give it a try.

Then serve "B"'s racks off of "A"'s roof system riser. Reasoning for this is that if you had an impairment in system "A" you only impact one system, either the roof or the racks not both within that particular area. OF course this all depends on the building configuration and whether you're manifolding the risers or have separate run-ins so it may or may not work in your building. Craig L.

The racks span an area that is protected by 4 roof systems. Can we use a single system to supply the in-rack and have all 65,000 sqft on a single valve? I thought that I read somewhere once upon a time that in-rack systems had to be zoned similar to roof systems i.e. 40,000 sqft max etc...
