    Runout a pipe feeding or returning from a radiator consisting of horizontal and vertical pipe
    Take off a run out's or branch pipe connection to supply or return main
    Risers a vertical pipe could be supply or return with flow up or down
    Drips a pipe dripping (draining) condensate from a steam pipe either from a main, riser or runout
    or branch

    Steam branchor a pipe with a take off from a steam supply or return main that feeds several takeoffs
    return branch

    Some might call a branch a sub main

    Thanks for that info!

    What's the difference between a runout and a takeoff ?

    The runout starts at a takeoff.

    What do you call a pipe that leaves the main and connects to a radiator? Its as if its both?

    The takeoff is where the runout attaches to the main.
