I put them this way on purpose. I thought it would look better from the outside. I have seen many discussions on this, but the main thing is to have the rubber gasket on the flange and not the nut side. When water leaks, it will go either way, leaks are not unidirectional.
Overflow box help needed

You could try using a street style elbow. One end is male the other female. Turn the system off, loosen the bulkhead nut so that you can slide the bulkhead out part way to give more room and then slip the male street end into the bulkhead.
The second hole would need to be drilled higher then then the first to operate as a herbie. The way it’s currently set up both bulkheads are below the water level. The second bulkhead is supposed to set the water level inside the weir.
It should look like this

Not if you use two elbows turn the main one down and set it for a full siphon with a valve.
Turn the second up and let it take a small trickle of excess water.
That is if there’s room from the top of the tank for the elbow to turn up without causing an overflow of the tank.
Op if you turn the bulkheads around there should be more room inside the wier.
I know you said you like the clean look but it will be easier to do the install of elbows and probably more accessible in the future as well.
Unless you can find a way to fit the elbows inside the way you have it now.

The issue with these retro fit over flow boxes is they are low profile and don’t have the room to fit the elbows. I wanted to set mine up the way you described but there just wasn’t enough room. If there is room for them then I would remove the weir and flip the bulkheads and install the street 90 on the secondary drain like your suggestion.
Hey guys, thanks for all the suggestions. For the Herbie style, yes the holes must be at different levels, but that was the purpose of using one elbow. in the end, I created my own elbow using a 2 inch pipe cut at 45 degrees and gluing it to another one cut at the same angle. There is no pressure there so not too worried about the build quality, if it fails at worse the overflow box empties in a power outage, but the sump can hold it, and eventually the sump overflow will be plumbed to a drain.
here is what it looks like installed;

Ahh I see now. That is a tight fit.
Glad you found something that works for you.
If you want to lower the water level in the box you can turn the home made elbow slightly to one side.

I love a crafty solution! Did you use PVC cement to weld the two pieces together? Or are you using a different glue?
