I'm trying to find 2D dwg blocks relating to sanitations, vip toilet units, disabled units and more and more. can some one direct me to where I can find those blocksThank youLunga

Most any reputable manufacturing company will have both 2D and 3D blocks available for downloading (FREE) on their website.  Some will be specific to programs like Revit while others will be specifically for users of AutoCAD and AutoCAD vertical products.  Here is an example of what I am talking about.  Manufacturer: American Standard.  2D symbols in both .DWG and .DXF file formats.http://www.americanstandard-us.com/resources/technicalfiles/search.aspx
