How do I associate manhole attributes with pipes?

[MarkButler1]

I have an AGOL map where we are field locating all the manholes in the sanitary system using Collector app.  Each manhole was inspected. The manhole feature class has attribute info for pipes such as invert, direction, material, diameter.  I now want to draw in the sewer pipes to connect the manholes in an ArcGIS for Desktop edit session.  What is the simplest way to associate or transfer the pipe related attributes from the manhole feature class to the pipes?  Has anyone run into this issue before?
