Outlets in SWMM 5 can have reverse flow
Outlets in SWMM 5 can have reverse flow (1) if the downstream head is greater than the upstream head (2), a flap gate (3) will prevent the flow reversal (4). An outlet can have both positive and negative flow as long as you do not prevent it by having a flap gate.
