I am in the process of uploading pictures!! Takes a minute, but they'll be up soon, I promise.
Mine is not an older one, its new and no air is trapped.<a href=showthread.php?s=&postid=12918567#post12918567 target=_blank>Originally posted</a> by Slayer311
let me be more specific, your overflow box has the 2 tubes that come over the edge of the glass which sucks water from the display down to the sump, at the very top of those 2 tubes, or possibly one large tube if its an older model, air bubbles can collect, if your flow is fast enough the air bubbles will be forced out of the system, i have the older style system with a larger tube and air bubbles get stuck at the top often and can break the syphon causing no more water to flow to the sump over time. Just check it from time to time to make sure no bubbles have accumulated
That makes sense. We will try to find flex that will go up into the fitting on the out part of the overflow. Is this glued just like the pvc fittings?<a href=showthread.php?s=&postid=12918505#post12918505 target=_blank>Originally posted</a> by asm481
The threads on the outside of your overflow bulkhead are not designed to hold anything. They are just to hold the bulkhead in place. Picture a giant bolt 3-4 inches long and a nut that threads up the bolt. Nuts and pipe are different kinds of threads and are not interchangeable. Clamping around the threads is an incomplete seal and may leak down the road.

Can you explain your pump return plumbing? What is that pipe coming down back in to the sump?

I skimmed parts of this, so if this is a repeat....
First off, even though your overflow is rated for 1200 GPH, there is no way it will ever be able to handle that much. I would guess it will be able to handle around 1000. There is only one overflow box that in my experience that will actually handle what it is rated for, and that is a LifeReef one.
Your best bet is to have a ball valve AFTER the Mag, just play with turning it down until they are matched.
You can see in the following picture the blue ball valve that is after my external pump is turned down a bit to match my overflow.
(( the black one before the pump is wide open and is only there for when I clean the pump ))
No, you didn't repeat...just reinforced So adding a ball valve after the Mag on the return side will not cause the pump to burn out?

so.. the overflow goes directly in to your skimmer as well? Then the water is pulled out of the skimmer by the small pump in the sump? Forgive me, but that doesn't look right. I however have an in sump skimmer so i could just be confused. It looks like that would totally restrict your drains flow rate.

No, it's the inflow to the pump you can't restrict.
