This dialog allows you to assign boundary valves for a flushing event.

On the Elements to Close tab you can specify the elements to close for a given area.

Click the Select From Drawing button to select the valves you want to serve as boundary valves. Highlight a valve and click the Remove button to remove it; click Remove All to remove all valves from the list.

Boundary valves can be any of the six standard valve types, isolation valves and pipes.

Each individual element can have their own notes. An ellipsis [...] button is provided that opens the notes editor.

As there is for events, there is a primary view for the boundary valves. In the Report View tab, you can override the default primary view and specify your own user defined primary view by clicking the Primary Report View button and dragging a box in the drawing view to define the view, or by checking the "Is User Defined?" checkbox, which makes the 4 coordinate fields editable, allowing you to manually enter in values.

You can also define Secondary Views in the bottom pane of the tab.
