I didn't mean to suggest that you didn't need access to low points. You do, and you need to put the sign on them or next to them, but you also need to note where they are on the general info sign. Too many low points drain get lost in the insulation. I think it was Bob that said inspections per 25 only had to be made from the floor (or that's what he meant 🙊), but Scott makes some good points about the difficulty that might be encountered for other activities.
