how exactly would i construct that for a design such as my over flow box? since i already have the initial pipes set up.

I kinda got a different problem, my drain is quiet, but when it drains into the sump, its noisy, with the air and all. Any ideas there?

Trigs, try a elbow pointing down in your overflow box. Cap the pipe above the tee on the outside, then starting with a small drill slowly go larger until the level in the overflow becomes steady and the drain quiets down (can also use a air valve). Once tuned, the air your pulling through the drain is at a minumun, you'll still get some gurgling but that's the nature of this type of standpipe.

For zero gurgling all I know of is the Herbie style but to be safe, they require two holes for drains.

Here's a variation on the Herbie, with layout out similair to what you have already.

I'm not convinced a third run is necessary but guessing I don't fully understand it.

how will i get the elbow to connect?

simple you want to slow down the waterflow to the sump a little this is what you do, put a ball or gate valve at the bottom of your stand pipe have it below the water line and then adjust it just until it stops gurgling. worked for me!

Not sure of your bulkhead size but they're easy enough to find (I bought some 1" fr Rona)
