Source Node (Reservior and Tank not included)

[Gehad]

Hi

I just began using EPANET and I would appreciate your help and advise.

My water network has no a reservior nor a tank. My network includes just links, and nodes (Junctions) I understand that I should input a negative head (pressure) for the source node. However, I could not do that. Please advise

Thanks,
