Any ideas on how to quiet an overflow box

[Mgus]

Just set up my sump the overflow is a bit noisy. Any ideas on how to quiet it a bit. Trying to get everything fine tuned. It is an eshopps hang on back overflow.

Does this use a Durso setup within the overflow box?

[Mgus]

I don't think it's a durso setup. It has a u-tube that goes from the strainer box over the rim of the tank where it goes into the overflow box where there is a baffle and it overflows to the drain where ther is a pipe covered with a foam cylinder

You know what I am going to ask, do you have a pic or link to the product? Most of these overflow from the tank to the overflow box via U tube and keep the primed water going by way of air pump or by sucking the air out. I'm trying to figure out if the drain is a pvc pipe upwards or if it has a silencer already.

fixed the link for you.

Well it looks like the U tube is overflowing in to a reserve and then it overflows on to an open channel. With that being said, where are you getting the most noise, from the drain section in the overflow, or from the sump where the water drain in to? What pump are you using and what size is your tank?

What if you did the following: Install a "T" in the pipe that runs from the box to the sump; install it as close to the botton of the box as you can. In the third leg of the "T" install a short pipe then a "90 elbow" pointing up. In the other end of the 90 install a pipe long enought to reach above the top of the box. The plan is just like what is used in modern plumbing so your sink can keep from pulling a vacuum and sucking the water out of the trap.
What do you think?

Agreed, try to pinpoint where your noise is coming from. Could help with solving it.

A lot of the nois is coming from the overflow box in the tank. And also the drain makes a loud gurgling sound once and a while. There is a 90 degree elbo below the drain that goes into a one inch hose that goes into the sump. The tank is a 125. The sump is a 20 long the pump is an aqueon aq1700. With adjustable flow rate from 264-449. I have it set somewhere in the middle right now.

[rickztahone]

Well it isn't because your pump is too strong that is for sure, so it isn't the rate of water going through it. Since you are getting the gurguling sound, you more than likely are experiencing pockets of air being taken in by the overflow. Is the overflow box adjustable in height by any chance?

[Mgus]

It is adjustable I've been moving it around a bit have it set low now trying to get more water in and try to avoid the air bubbles I haven't heard it gurgle for a while. Do you think putting foam in the overflow would cuase flow problems. I'm thinking of trying a coarse foam to muffle the sound and not slow the flow to much.

There is a small pipe that sticks a couple inches above the drain pipe I think it is supposed to work like that to keep it from getting air bound.

I just set up an overflow on a 120 & it had two drains out with 90's & very noisy. I took out elbows & ran straight pipe down to 45's & then to sump & quited down considerably . I think the elbows caused too much of a restriction & would cause an airlock until it gurgled. Had to move sump closer to overflow but very happy with results. Hope this helps or at least gives some different ideas . Good luck with your project , mike d.

Try stinking airline tubing down the drain hole. Once you find the quiet spot, secure the airline tubing to keep it from falling through.

[rickztahone]

The more submerged it is, the better. You can do 2 90's with an airline tube pocking out of the top for air, this will quite the setup considerably.

Use a sponge in the drain

The air line tip worked great took care of the gurgling sound.

One other thing I have to fix when I made the output pipe I made it to fit right on the edge of the tank but forgot to add length for the thickness of the hose. It is only half submerged and makes a lot of splashing. I'm gonna make up a new piece for that and might add a spray bar. There is a good amount of current in the tank I am also running 2 fluval 406s. Thanks everyone for all the help. I'll try to put up a video when I get everything fine tuned.

If it were me, I'd be very nervous about your sponges getting dirty and have your overflow back up. In that situation your pump would keep feeding your DT water and it would overflow. This may just be me though. I like failsafes

100% this. I'd never use a sponge in that way just in case this happens. I know our best intentions are to keep it clean but that one time something gets sucked up that its not supposed to will be the 8 hours you are gone at work.

I came home to my SW tank overflowing one day. Luckily happened right as I walked in the door. What happened? A simple sponge had gotten clogged up.

The sponge does not fit tight in there it is kind of floating free in there. Do you think overflow will still be an issue like this the sponge is cutting down on sound and and air bubbles

[rickztahone]

How about sticking some eggcrate there just to be safe? Wouldn't hurt.

[MKD]

From your information, does pump come with aet up? I think 1" drain hose is too big for your pump, It creates air pocket. Just like Rick said, the more submerge is the better. I would get strong pump or ball valve at end of drain hose into the sump. It looks like ball vavle is better choice for you.

Check it out. 1" hose flow rate ~900gph
