Create the Domestic Cold Water System

1. Select one or more plumbing fixtures in the plan view.
2. Click Modify Plumbing Fixtures tabCreate Systems panel Piping.
3. In the Create Piping System dialog, specify the following:
   • System Type: the type of fixture selected in the view determines which System Type it can be assigned to. For a plumbing system, the default system types are Sanitary, Domestic Cold Water, Domestic Hot Water, and Other.

     Select Domestic Cold Water.

     Note: You can also create custom System Types to handle other types of components and systems.
   • System Name: uniquely identifies the system. Revit suggests a System Name or you can enter a name.
