Deleting Pipe Sizes Smaller than 1"

Good evening,


I'm working on an automatic fire sprinkler system in Revit MEP.  Typically, these systems do not use pipe sizes smaller than 1".  As such, in Mechanical Settings, I deleted these sizes for all materials, connections, and schedules/types.


However, when I try to automatically connect a sprinkler with a 1/2" connector (using the Generate Layout and Connect Into tools) into a pipe, Revit still uses 1/2" pipe.


The heirarchy I'm trying to achieve:


sprinkler --> 1/2" x 1" reducer --> 1" pipe


But instead I get:


sprinkler --> 1/2" pipe


How can I permanently delete 1/2" pipe?


Thanks for your assistance.

I think I know what the issue is here. If you delete the pipe size you may not be able to connect as REVIT will not recognize the size. The easiest way s to use the space bar when you connect & then once you inherit size & elevation you can change to 1". Unless they are all the same height & if that is the case I would punch in 1" & the height, then just connect & go.
