Comparing Attributes from Adjacent Line Segments in a Geometric Network

I have a geometric network of connected wells, pipelines and facilities. The wells act as the source nodes, the pipelines act as the links and the facilities act as the sink nodes. I also have a point feature class at every pipeline junction section already created from a different script. What I'm trying to do is use FME to create a new point feature class (call it Attribute_Flagger) at any pipeline junction for the pipelines that connect at a junction but have a mismatch in the MOP (Max Operating Pressure) or H2S fields. Below is a diagram I created to understand this relationship better.
