Hi @ameer.mansourWAK8Y 

Trying to Change Type using Revit API? or Manual. Can you please explain the Exact scenario? 

[NGM_AiYo]

Maybe by DMU.  Add trigger  Element.GetChangeTypeElementAddition()

[ameer.mansourWAK8Y]

yes using revit api.

Have you tried UIDocument.PromptForFamilyInstancePlacement method?  It takes a FamilySymbol as input.  Find the FamilySymbol of the pipe type to use.
