Here are the plumbing photo's, if anyone has any questions go ahead and chime in.
Overall
2-1.5" drains, 1 Durso and 1 lower drain. I got this idea from a friend, (thanks Psyire) it keeps the air and the noise down. I use the ball valve to reduce the flow from the lower drain so that the majority of the water ends up down the Durso so that I can control the height. Man is this system quiet.
This next shot shows how the Drain lines are running into the sump. You'll notice that each line has 2 ball valves, one for the flow into the sump and the other for flow into the floor drain pipe running along the bottom behind the sump.
This photo shows the two PS4's pushing water back up into the display. These have to be the quietest pumps I've heard. The ball valve's here are to either push water up from the sump, or to push water up from a Mag 18 in the freshly mixed saltwater reservoir for water changes. The idea is that as I fill up the display with fresh saltwater that is 1 degree colder than the tank water, the old tank water will fill the overflow and I will turn the drain valves to allow that water to go to the floor drain.
These are the drains from the tank and sump (if it overflows) into the floor drain pipe.
This is the fresh RO water and the Fresh saltwater reservoir, also with the safety of an overfill going into the Floor Drain Pipe.
And Lastly the Floor Drain pipe into the Floor Drain
If I get water on the floor, I'll be really scratching my head.
