Abstract: A door system includes a doorframe having opposing vertical jambs, a door pivotably coupled to the doorframe, a threshold extending between the opposing vertical jambs and providing an upper surface that defines a valley, and a dam removably mountable to the threshold at the valley. A valley seal interposes the dam and the threshold at the valley when the dam is mounted to the threshold and thereby generates a sealed interface between the dam and the threshold.
