I made mine last night and installed but it had a terrible sucking noise through the cap and no matter what I did I could not get rid of the noise. I have a 1" bulkhead that and the pipe was 22" for a 24" tall tank. The overflow goes down to my sump and the pipe goes about 1 1/2" to 2" below the water level in my sump. I am running a Little Giant 3mdq-sc and pumping about 850 gph through the pump. I had to put the Durso back on and it does not sound bad but was hoping for a more compact and like the idea that it is a 1" pipe all the way to the sump.
What am I doing wrong that I get the terrible air sucking noise. I cut all but three of the braces like you.
Thanks
