Question about plumbing

[ajremington68]

New to me 180 and I built all this plumbing but the left side overflow is doing most of the draining is this normal? Also it is level. Then once I put the drain into the sump I put it u der water but it is bubbling would I add a gate valve or ball valve to this to tone it down so it doesn’t drain as much and instead goes over to the other side? Also would that stop the noise or would the other side bubble too? Finnaly on my return nozzles there is a pin hole drilled into the top to stop back siphons I assume could I cover it with silicon to plug it? With that the more I turn up the return pump the more it sprays. Also I have the jaebo dc8000 or whatever and I can’t move it past like 3-4 on the controller without it draining the return chamber how can I fix this so I can crank it up?

The floss maybe slowing flow to return chamber.
Pull it out right now and see if that fixes your issue.

That pump may be too big.

If both drains are gravity fed then they should flow equally if the tank is perfectly level, but this is almost never the case. if one overflow is slightly lower than the other then it will take most of the flow.

This is what I assume to be happening and I don’t mind one being the work horse but if you listen in the video how do I tone the sound down?

I will try and pull the floss. The sump came with 30 micron sponge in the section so I assumed it to not be the problem. And the return pump that this came with was 1 size down but he said it was cranked all the way up. If it is gravity all the way around would more water just need to drain to fill the return section? Or maybe I have to add more water to the return section?
Also this is the pump I was told to get by others so hopefully not to big it’s about 2000gph

Anybody got previous experience with a noisy drain and how you fixed it?

 

[MarineandReef Jaron]

Do you have any mufflers on the drains? Is there a stand pipe?

What do you mean? Like what would a muffler look like?

Would a muffler get added on to the pipe under the water? If so no I just have 1in pipe under the water about 1in and that’s all.

Also my overflow compartments both look like this if this helps solve my problem.

If you have 2 overflows they have to be run as durso. If you're getting air mixing with the water and bubbling in your sump then you need to get more air into the line. What happens is the water is pulling air down with it and not letting the air breathe. There should be an air intake at the top of that durso. I think I see in the last picture you posted, it looks like a little nipple. You need to open that up if you want to push more flow through.
Edit, in fact it looks like it's underwater! That should not be underwater, that's your air intake to quiet down the durso.

This is from an online picture not my tank. In my tnak it’s not underwater but the same type. So you say if I want to crank up my return pump and drain more water the little air hole on the top I need to drill it out and make it a larger diameter? Now before I do that will this cause it to gurgle? I want to avoid that at all cost but still reduce the noise in the sump.

It will release the air allowing only water to flow down the pipe. Drill a little bigger, test it, drill more, test it, until the flow gets steady. No worries if you go to big.

Okay with the attached video you can see my drain height and style as well as the pipes that drain into sump are 3in off bottom. Could I get ball valve and add them to the drains and close them slowly to fill it with water and remove the air that way? Just fearful of drilling the top of the drain cuz I cannot go back after that.

Lift the overflow pipe up and bring the water level in the overflow up. And make sure they are even side to side

You could, but then you run the risk of a clogg and potential overflow flood.
All that pipe in the overflow you can re-create. A simple trip to home depot and a few dollars. Either try it with HD parts so you don't "mess up" the originals, or drill what you have and if it's messed up, recreate with HD parts.

The air is getting sucked down the tube causing all that bubbling.

Your drain pipes need to be about 3 to 4 inches under water to muffle the bubbling and prevent any splashing.

For the hole in the return I would try twisting the locline to get the hole to point downwards.
