To Reverse the Flow of a Plumbing Run

When you reverse the flow of a plumbing run, you cannot see the change in direction unless flow arrows are applied to the run. However, you can determine it by looking at the sweep on the sanitary tees.

To reverse the flow of a plumbing run

  1. Select a segment on the plumbing run in your drawing.
  2. Click Plumbing Line tabCalculation panelReverse Flow.
  3. For information on applying flow arrows as you draw, see Specifying Plumbing Preferences for Labels and Flow Arrows.

    Note: Reversing the flow of a plumbing run does not propagate to the connected objects. If you reverse the flow of a plumbing run after performing sizing calculations, you need to resize the run.
