Plumbing help

On the cor 20 (no apex yet) but at about half power now it will not let the return suck air from surface. With pump at 100% it will suck air.

Does your siphon looks like this

If so - the open end of the T will suck air for sure. Make it at least 1.5 inch below the water or put another elbow on it (facing the bottom)

Hey glad to see im the only one that doesn't sleep. Yeah Lasse it does look like that. I'm not sure how far under water the T is but im pretty sure that it wasn't getting an air vortex sucked into it. Will try the 90 when i get off work with the rodi tubing. If that doesn't work i will try extending and shorting the drain to the sump. Hopefully it works.
 
I´m at least 6 hours before you :) Just awake. :)

If it not is this fault - the leak must be in/at the outlet part of the valve or after it - hence air is sucked in as it does in an injector. Why - because if there was a leak before the valve - you would have water out instead of air in. I can´t see what type of valve it is. If it is a ball valve - there is a small chance that the fittings for the axis of the handle can be damaged. In some of these valves - there is a tightening nut just below the handle.

If you wait 42 years - when you have learn all of my mistakes (and probably some new caused by yourself) :) As an old boss to me said - it is better to get the insight that you are a total idiot compared to face a problem with no solutions :) He said it the same time as he leaned down and plugged in the power plug into the computer that he try to start for 5 minutes :) :)

Haha well said. Thanks for the insight. The bulkhead on the sump, the pipe dropping from bulkhead into sump was not glued and sucking all the air. I realized the problem as I was pulling the pipe out trying different sizes;Facepalm... now running 100% quiet. Thank you everyone on here for the ideas. And sorry for my idiocracy.

That'll do it! A few less bubbles now? :)
 
@Amoo did you end up getting the trigger Triton sump? I was looking at your build thread and saw you have the same tank and sump as I do.

Yes I did, it's been sitting in the box on my back porch pretty much all week. Haven't had a chance to do anything with it yet or even inspect it. Tank should be here this week.
 
You guys have this one pretty much covered. What I see and hear is the issue of nice is being caused by the bubbles echoing up the return pipe. I have seen where some do not have the return pipe underwater but above the water.
 
Anytime plumbing is immersed under water, it will be dead silent. Extend tube/piping below water surface and your experience will be silence
