Silence the overflow pipe?

[Brancho]

Any advice on how to silence my overflow pipe?? It's 1inch and currently has this spiral overflow silencer that does nothing much!! I've been told I need to slow the flow down the pipe a little or Increase the return pump flow??

Gate valve gate valve gate valve

Have 2 drains. 1 primary one emergency. Put the gate valve on your primary and close it until the water just barely trickles into the emergency drain and with 100% confidence can tell you your drain will run silently.

I don't think I have that option to putting another drain (emergency) see attached i do have what may be an emergency outlet? (Green pipe) But I was think of adding a adjustablr flow valve to the overflow before it goes into the sump?

You can change it over to a durso standpipe. If tuned correctly, they can be very near silent. Just google that and there is a full walkthrough on how to set it up.

I have the same exact drain on a cylinder ProClear tank. Pull out the spiral silencer. I agree it does nothing in regards to lessening noise. Then take some flexible tubing (i used approximately 6-7" or so) and fold it up a few times so that its bunched and wedge it in. Works like a charm. Near silent. The most important part will be to ignore everyone that will tell you you're asking for trouble lol but dont have the noise issue. I've had mine running for 2 years. Once in a while I'll take out the tubing to clean. Check out this video.

That's not quiet at all in the video. The only thing you should hear is the water coming into the overflow area, not the drains themselves.

I'm at over 2600gph at a ful siphon and it's way quieter than that with a herbie and a durso.

That's not my tank. Mine is quiet

So just small flex tubing I don't cut it just fold it and wedge it? So I'm jut basically restricting the flow in?

Yes you need to constrict the flow to slow down the amount of air your drawing in. That air is making the noise

What is the black hose?
What is the Grey hose?
Are they opposite ends of the tank?
Do you know the size of the hole for the green and Grey hoses?

Grey could be your main drain and green be the emergency. Black the return.
You just need to make sure the emergency can handle all the flow if the main gets clogged. This would be as silent as you could possibly be.

Same for @kados if you pull your return line and make that your emergency, flip a return over the back side. You will have a dead silent and safer running tank with more flow.

Mine is good with the mod. This a cylinder tank with 360 degree viewing so all plumbing is hidden.

I have Herbie on my other tank.

Black is the overflow and the grey is the return the green is drainage only a fitting under the tank few holes on the tank bed. Yes opposite ends of tank and pretty sure it all the same size same screw fitting

So if you follow my plan I laid out, the main drain would have a gate valve. That will be just above the sump. Emergency line is a straight shot to the sump. Both lines just below the water line will make them quiet. Other side of the tank is your return just like you have it now. It will be extremely quiet and much safer.
The gate valve is for tuning for a full syphone and keep a trickle of water down the emergency line. if for any reason it gets clogged, the emergency gets kicked in and the tank will gets noisy because of the air down the line. It alerts you, clear the drain and back in business.

I should note that the main drain should be half way down in your overflow box and the emergency will be just below the weir. This way you won't get the syclone effect with the full syphone.
Let me know if you have questions and I can walk you thru it.
