To edit text column, please see the EPANET user's manual, because it exactly what you need.
On the other hand, you must remember that some GIS elements (shortpipes, pumps, valves) are NODE on GIS but ARC on EPANET, You must know that you need to identify that elements on your rules and controls as ARC (because EPANET side). Remenber that nodarcos changes his id when are transformed (adding _n2a as sufix of node_id)
IN addition, node_id, arc_id and sector_id columns for that tables must be filled with ONLY ONE of the elements related on the rule, in order to activate it and send to the model.
