Revit drainage line colour

[PavPev]

Not sure if this is the right section to ask this, please let me know if not!
I am trying to show drainage lines on my site plan. I have positioned pipes and used a graphic override to show the centreline as a thick blue dash-dot and that works ok.

The problem I have is I want to show Foul Drainage and Surface Water Drainage on the same plan - I have used 2 different pipe types to draw them but they both look the same in plan view. Is there a way to specify how the centreline looks by Pipe type?

I would like to be able to hide the pipe outlines, without hiding the centreline of the pipes too if possible, but at the moment this is a minor gripe

Any help is much appreciated, Thanks!

The best solution I've come up with so far is to use the linework tool to apply a liner style to the pipework. This isn't ideal as it doesnt show the pipework through the floor construction (in plan) and also for some reason you cant apply a linetype to the centerline, even though you can change the centerline appearance in Visibility/Graphics?! So I ended up applying it to one side of my pipes, and turning the other side invisible so it just shows as one drainage line. It'll do for a 1:200 site plan but at 1:50 you can see its not centered up properly
