I think what he was showing in his diagram wasn't a fitting at the bottom of the tank, but a fitting on the outflow line. I'm assuming this would allow for an emergency drain of the tank in case a pump out wasn't possible -- but I'm just guessing. I noticed in your drawing you recommend all fittings mount on the surface, with an intake pipe drawing out. Our system is pretty basic (no macerator pump, manual head).I am at the advantage of working on 3 to 4 systems a year for the past 10 years. I get to see what works what won’t. Some… I learned the hard way.
There is no way in hell if I did my own tank I would put a fitting at the bottom of it. I have a different perspective than most because I have to work on so many.
Another myth is that you need a separate tank to supply the head if going f/w. A simple check valve will do. I usually do 2 check valves for piece of mind. Just be careful not to tie into a pressurized part of the FW system if the head is not built for it.
