Modeling Pressurized System with SimHydraulics

I am trying to recreate the plumbing infrastructure of a common residential home. In my simplified model, I am only concerning myself with a single fixture, as model by the Orifice with Variable Area Slot and trying to measure the volumetric flow rate through the fixture and the pressure drop that it creates.
My problem is that the flow sensor is measuring a flow rate when when I expect there to be none and I wish to know if I have connected my model improperly or if using the orifice block was a bad choice.
I have attached a picture of my current model and results.

We'd need to know the parameters of the orifice block and the actual displacement you're feeding it via the Signal Builder block. There's definitely a large enough flow area throughout the whole simulation to maintain a flow rate of 23.5 gpm.
... either that, or you made the leakage area really high, which is unlikely :)

Right, so that's why there's still a significant flow rate going through the orifice even when the source is zero... because your initial opening is 0.2.
Does this mean the model makes sense now, or is there still something weird about it?
