    I have dampers in my heating pipes but no levers. There is screw and wing nut and the screw has 2 flat sides. Are the flat sides of the screw any indication of which way the dampers position might be -open or closed?

      Not really.

    Ny husband wants to put PVC pipes in a main floor duct to direct the warm air flow into the 2 rooms that the one duct now services - he wants to do this because the warm only comes out of one side of the duct so only one room is warm- can he use PVC pipe inside the duct to direct the hot air flow? Is this safe?
    Thanks

      The heat won't hurt the PVC. If that's what you're asking.
