I am a new user to WaterGEMS, and I am trying to build a system from scratch.
I have figured out a number of shortcuts, but this one is perplexing to me.
When the program assigns valves to the nearest pipe, it assigns them at the midpoint of the pipe. This is problematic because it changes the layout of the system by putting valves on the wrong side of fire hydrant laterals.
The attached image shows a point in the system where you can see three instances of this. Three separate valves (arrows) are assigned to the nearest pipe at the point on the dotted line. But that point is on the wrong side of a lateral with another valve and hydrant in all three occasions (in boxes).
Is there a command that assigns the valves to the nearest pipe at the nearest point? That would make a lot more sense, to me.
Hello Mike,
The dashed line shows you the associated pipe and will always connect to the midpoint. However in the calculations that account for the location of the isolation valve, such as criticality and flushing, it will know the exact location of the isolation valve based on where it is in the drawing. You can see in the isolation valve properties the property "distance from end point".
In your case it is hard to tell, but it appears that your hydrants may not be connected to the pipes that they appear to be overlapping with? For example the brown pipe at the top should actually be three separate pipes. I would recommend zooming in; check if the hydrant is connected to the pipe via a junction. There are some network navigator queries that can also help, such as "Find initially isolated elements". More on that here:

If that does not help, please provide a copy of the model for review:
