When there are no pipes connected to a junction structure, the rim and vertical pipe clearance take precedence over the sump.
The following sections describe the resize behaviors on junction structures that have no connected pipes.
When you move the structure’s rim up, and the Control Sump By property is set to Depth, the sump moves up the same distance as the rim.
When you move the structure’s rim up, and the Control Sump By property is set to Elevation, the sump moves up the same distance as the rim.
When you move the structure’s rim down, the sump does not move. You can move the rim down, but only to a location just above the sump. The rim must always be above the sump.
When you move the structure’s sump up, and the Control Sump By property is set to Depth, the new sump elevation can be below, at, or above the vertical pipe clearance area. This does not affect the rim elevation, and it sets the sump depth to zero.
When you move the structure’s sump up, and the Control Sump By property is set to Elevation, the sump can only move up as far as the bottom of the vertical pipe clearance area.
When you move the structure’s sump down, the sump is moved to its new location (new sump depth), but the rim elevation does not change.
