getting loud gurgle out of your overflow!

[Trigs]

Hey everyone how do i make it so my gurgle sucking sound goes away so its quiet? its ****ing me off so much heh any ideas would truely help i need it to be quiet since its in my room!

[spoot]

Some of the tried and tested methods are Durso Stand Pipe, Hofer Gurgle Buster, Herbie Standpipe. Do a search here, or on google.

really easy cheap fix that works is to cut a length of flexible airline tubing and feed one end down into the overflow and leave the other out and free in the air.
This will greatly increase the airflow and mitigate a lot of the gurgling.
try it and see.

What does your overflow look like right now? Just a bulkhead? Overflow box? and stand pipes? etc.

[Trigs]

well its a simple glas over flow with bulkhead to pipe down

[Trigs]

what exactly do you mean "whatigot" ?

Internal, external?

Internal, external?

internal

HA.
well then scratch what I said.

How many drain holes do you have? 1 or 2? If 1, build a Durso or Stockman standpipe. If 2, use a Herbie system.

[Trigs]

1 drain hole 1" let me post a pic

Do an external durso for that setup and it should quiet it down a bit.

[Trigs]

any places i can get an idea on how to do this?

how exactly would i construct that for a design such as my over flow box? since i already have the initial pipes set up.

I kinda got a different problem, my drain is quiet, but when it drains into the sump, its noisy, with the air and all. Any ideas there?

Trigs, try a elbow pointing down in your overflow box. Cap the pipe above the tee on the outside, then starting with a small drill slowly go larger until the level in the overflow becomes steady and the drain quiets down (can also use a air valve). Once tuned, the air your pulling through the drain is at a minumun, you'll still get some gurgling but that's the nature of this type of standpipe.

For zero gurgling all I know of is the Herbie style but to be safe, they require two holes for drains.

Here's a variation (http://www.reefcentral.com/forums/showthread.php?s=&threadid=1310585)on the Herbie, with layout out similair to what you have already.

I'm not convinced a third run is necessary but guessing I don't fully understand it.

how will i get the elbow to connect?

[chevyjaxon]

simple you want to slow down the waterflow to the sump a little this is what you do, put a ball or gate valve at the bottom of your stand pipe have it below the water line and then adjust it just until it stops gurgling. worked for me!

[mr_alberta]

That's not the best idea unless you have a backup drain otherwise one day your drain will plug and you'll come home to an empty sump and wet floor.

[Trigs]

okay well pretty much
what i have is a overflow to a T the pipe goes up to a cap with a air hole then down to a 90 degree into a straight pipe to a ball valve then to another 90 to my sump with a micron bag over

Not sure of your bulkhead size but they're easy enough to find (I bought some 1" fr Rona)

free in the air as in out the top by the over flow? like out the cap?
