    adding another run

    Hypothetically speaking if another 6" supply is added almost at the end of a run(there are 2 supplies running in opposite directions at the end already), just wanna know what would this hypothetically do to overall staic pressure, and the amount of air going to the already installed 6" supplies. Thanks.

    Decrease the amount of air the other 2 supplies.
    Won't drop static much, since its at the end of the trunk.

    How many times must one fix something before it is fixed?

    Thanks you guys as always are great. The 2 end runs supply the exterior wall in townhouse. The extra run would supply a bit of exposed wall on the side , 3 feet or so. george

    Your throw could drop off enough that it doesn't cool as well as now if they are floor regs. Or it could help.

    A damper in the new run will make it so you can close it off if it hurts the room.
    I'm sure your contractor knows that.
