No drain pipe???
I appreciate a lot of the graphics, but some of them I have no idea what purpose they serve other than say, hey, look at this graphic I can create - including this one. IMO, a graphic should be something that would be useful for Inspectors to help show a condition/defect or the right way to do something. For instance, a sump pump connected to the main sewer line with a red x saying prohibited connection or something equivalent.
