If we are validating a model in water gems and want to insert level of the junction directly can it be possible in water gems
As a follow up to Yahodhan's post, Watergems default junction elevations are 0.00. This can lead to massive overestimation of pressures! If the system you are modeling is at an average elevation of, say, 400 m, you should adjust junction elevations appropriately.
To avoid this I suggest using HGL instead of pressure.
