No.
Manifolding multiple systems on a single run-in is common. Just don't get too crazy. Depending on the building layout, occupancy and other factors, consideration for putting all your eggs in one basket needs to compared to costs for multiple run-ins. In certain buildings while placing all the risers and hose systems on one run-in may be permissible, it is often better to split systems up and have run-ins in different locations so that if one system was down, hose lines could be pulled from an adjacent system to the impaired area. Just saying it's good to think about what would happen if everything was in one place and an impairment occurred. Can you easily design it minimize impact or does cost or logistics out weigh the risks? Craig L.
