So, I am fairly new to the MEP side of Revit.  I attempted to model a Glycol Loop.  I was stupid and did not realize i had to change the pipe system as I was drawing the pipe (thinking i could draw everything, and modify that later).

Well, now I have a model with all of the pipes drawn (lots of them), but everything is coming up as Hydronic Supply.  I tried selecting the pipe and changing it to Hydronic Return, but that isn't an option.  I have disconnected all of the pipe from all of the mechanical elements, but I still can't find a way to force the pipe to be Hydronic Return.

Is there any way, aside from deleting all of the work and redrawing all of it as Hydronic Return to get it to the right system?  Any help is appreciated!

So when you select the pipe the System Type 'drop down' property is disabled ? See attached.

@dgcad, replying to a nearly decade old post here, but I am using Revit 2019 and am having the same problem. I have disconnected the pipe from all mechanical elements (and fittings!) and am unable to change the system the pipe is in. I have attached a picture of it looks like. I am testing how to work with system by drawing a simple loop of pipe starting with different system types. I have found that if I start with 'Other' and then disconnect a pipe from everything (as also shown), I am unable to change that pipe's system to anything other than 'Other.'

Any suggestions? I have found on other forums online, that the only way to overcome this, is to simply remodel everything, which seems like a huge pain.
