This is our first time running a durso and I’ve tried it a couple of different ways to no avail. After I stopped the return pump I noticed the left durso is drained completely and the right doesn’t even budge!? what the heck!
The other issue I’ve seen as I posted before is that j can’t seem to get the bubbling in the sump to chill out!
It’s funny how the drain which is 6” from the sump isn’t draining properly even when I completely plug the left drain, and that left drain really does it’s job. I’m at a loss now. If you look closely at my picture you can see the water lines AFTER return pump has been turned off.
I would say the farthest drain is draining more because of the longer run creating more suction before the air breaks, also the right drain you can see the water level is right at where the flat part of the tee is at so I would say it’s breaking syphon there. also try putting some valves on them to control the bubbling better.
Are they quite when the pump is running? Do you have air holes on top of them.
Keep in mind the first picture is with the system turned off. I just ordered some union valves which will be in on Sunday and I’ll get them set up then.
However. If I shut the flow off of the left drain completely the right drain barely keeps up with the lowest setting of my pump. As a matter of fact the pump wins. I would think the right drain would work best since it has barely any vertical run.
When I plug the hole on the cap with my finger on the right drain nothing Happens but when I plug the left of course the water raises.
What do you suggest I do with the valve?
Bahhh! I should have drilled and done a bean animal. But my wife wanted no plumbing on the back of this tank so badly.
Not sure what pump you running, but 3/4” bulkheads are rated about 350gph each.
Also when you plug hole on cap it should cause a full syphon and drain faster and should make water go down in overflow box not rise. Only thing I can think is farther one is creating more suction as it is farther run more pull.
You could remove the stand pipe on the right and see if your plumping keeps up with your pump.
Also I guess I am confused at what you are trying to achieve? Are you trying to get them to level out when pump is off? Does it run fine when pump is on?
So on the right side is that the water level when pump is running also?
Just as a guess from a foggy old man. I think the right drain has an air lock in it some how. How far under water is the end that goes into your sump. Sometimes if too deep air will not purge and only 1 drain will work

I wasn’t trying to bash you at all sorry if you took it that way not what I meant. What size pump are you running gph? Also with the valves you can dial each drain in so they run the same.

I didn’t take it as anything! I appreciate the help. I think the same about the valves. But if I can’t increase the flow of the right drain and together they barely keep up with my jebao dct 15000. I ran this pump just fine I our previous 150g with a bean animal. Wanted to keep this system clean so we chose bottom drilled.
Smacking my face on this. Even after $300 custom overflows and $200 of plumbing. Haha. What a mess.
Without drilling or without plumbing on outside because you could change returns to drains and have returns on outside back of tank. But Slower flow would be your best bet. Not sure how many gph is on your pump at slowest speed. Also slower flow should stop the bubbling also with slower flow you can control drains with valves to make them equal.
Tank is 265g. Sump is 55 a large system. I’m a for slow movement through sump so water gets more time to run through fuge and calcium reactor effluent and Heaters etc. Didn’t know if it was a reefing no no to downsize a pump for such a large system but I’m all for it.
I definitely will get valves in also. But I’m still baffled as to why when I stop the system completely the right durso doesn’t drain all the way.
