    911, just remember that chart doesn't stand alone -- all those suctions have to be off the same side of the truck.

    It's an alternate -- either your full capacity through a single intake, -or- through the size & number listed -as long as- there all on the same side of the truck.

    A typical 1750 mid-mount pump has one intake on the drivers side, one on the passenger so it must be capable to do capacity through a single suction.

    This also explains why most of the pics I've seen of trucks with very large pumps have them rear mounted -- all the suctions come off the back i.e. all off one side.

      I was not aware of that, the only thing I can remember is reading the chart on suction tubes, I'll have to check my nfpa book agian when I get home.

          If you don't want to take time to take your intake off just turn the piece around and use the capped suction.While it is true pumps are rated for one side suction on short lifts you CAN gain volume by utilizing both suction ports.T.C.

            The easiest way is to have valves on your steamer ports, thats what we did an our last tender. Nobody seems to do that though.
