The 90 degree elbow you have at the top of your Durso should be a 'T', not a 90. The vertical part of the 'T' gets a cap. The horizontal part of the 'T' gets the 90 degree elbow to face down. Drill the cap with at least a 1/4" hole. I think the hole your tubing is in is too small.

I just read about the following recently..though I cannot recall where and found it very interesting since the water level in both of my overflows is different and I couldn't understand why...(both of my durso's are identical in size/configuration)

The info I found said that the length of the piping that extends beneath the water in the sump also makes a difference in how much water is in the overflows. My drains as they go into my sump are pvc with a T fitting & 90 degree elbow (just like the durso in the overflows) and the elbow is directed to slightly above the waterline so that the air in the lines can escape...makes a little less noise/bubbles that way.
Hope I described that correctly. Can post a pic if needed.

there's a few things u can do. i have the stockman instead of durso but the principle should b the same.
1.) modify the pipe to be longer(rising the length to the exact height u need)
2.) drill the top hole bigger n use a bigger tube(more air get suck in so drainage slower)
3.) make the intake of the durso smaller
4.) lower the pump output
5.) split the outlet into 2

btw: a lot of factors affact the level of water in your overflow:
1.) height/type/size/airtube of standpipe
2.) the flow config. of inlet pipes
3.) the height of tank to sump
4.) the amount of detritus in tank
5.) the humidity
