A FDC is another valid point but the circumstances may be an over riding factor. I'm was going to ask the AHJ about that but haven't until I'm able to go through the whole job. There's another thing, the containers are connected to the underground via a black plastic pipe aboveground. I'm getting the submittals on that pipe tomorrow. And the underground has no way to be flushed or a pressure gauge on the underground to do a pressure test. Just another day and another project. Sent from my iPhone Aaron M.

I'm doing an inspection and I'm not sure IF check valves are necessary.
