As long as your emergency drain in higher than both drains,that is good.
your main drain should and looks like it is lower than than your secondary drain and I don't see air intake to it a it needs it unless its fully opened.

Emergency drain is highest. Yes main is the lowest and it is not suppose to have the air. It runs full, controlled by the gate valve. Its set so a trickle flows in the secondary. If the water level reaches the end of the air tube., then then secondary also goes to full flow.

your return line when ready I would face it flowing towards the lengh of your tank as one blow or a spray bar style hoovering almost under your water main tank.

Thats the plan Eli.

Silicone work looks sloppy hoping its good with no leeks.

Yup I do the most sloppy silicone work on earth. It was done proper at first, then I add a second layer over it all to protect it. None of it will be seen , so dont care about the look. Not that I wont this time..., but never had a leak in 30yrs.

Union on main drain is useless if adjustments is needed when testing.
I would have use gate valves never ball valves as they are really pain to work with.

I dont understand why the union is useless. Its there to separate the long drain pipes that go through the wall, so I can repair of move the tank out if needed. Plus I can change the horizontal angle of the pipes. I do have a gate valve on the main drain. Thats the only one needing adjustment and why I went with the gate instead of ball. The other ball valves only purpose is to shut the lines off for service work or something.

Last is test your lines by filling the tank and test for leeks and proper drains.

Now can I see more of your clams

Yup, I will be doing testing for sure. Thanks Eli.
