It is probably the cleanout based on what the plumber told you. Last summer I stayed at my deceased father-in-law's property for a month. Thought I would have to haul the 5vr out to dump the tanks at least once. Since he had the world's narrowest driveway with deep ditches on each side, I asked my brother-in-law if he knew if there was a cleanout since it wasn't visible. He told me it was about 2 feet away from the house out from a little x marked on the siding. It was about 6 inches below ground so I dug it up, took the cap off it and dumped my tanks. Sure saved me from a lot of frustration in getting in and out of that driveway.
