Noisy overflow pipe

[DeadmanZ]

Hi bros... I'm having problems of noisy overflow pipe(sound of water gushing down at the 90 deg elbow)... Did some search online and read that a material call 'mass load vinyl' will be able to absorb the sounds from piping if it's used to wrap around it.. Anyone have tried the above method? Or anyone knows where can I buy this material? Wouldn't mind trying out if it can solve my problem! Thanks for looking! Sent from my LT26i using Tapatalk 2

what is the size of your pipes? i got a couple of maggie mufflers that might help.

[DeadmanZ]

Hi bro. Thanks for the reply.. My piping size is 2" Sent from my LT26i using Tapatalk 2

my maggie mufflers is 50mm, should be around there but best if you can try and see if it fits first

Hi bro,

How it works?

Here's the website -- http://maggiemuffler.com/

I have been using durso since i started reefing but for my last setup tried this. It is definitely silent, takes less space and easy installation and maintenance. You may view it at work in my tank if you wish

Oh bro.. It's not the gurgling sound of the water being pull down.. But rather its the way down to sump inside the pipe where water reaches the 90 deg elbow.. The water hitting sound.. So actually thinking of covering up that particular part.. Sent from my LT26i using Tapatalk 2

ahh.... then you just need filter sock...

[DeadmanZ]

Nooo... Not the output of the pipe bro.. Hahaha... I don't know how to explain.. Grrr.. Sent from my LT26i using Tapatalk 2

Probably a gate valve to regulate the flow of the downpipe. Gate valve can control/restrict the flow to fill up the 2" pipe. If the 2" pipe is fully filled, there wouldn't be any noise from the falling water that hit the elbow.

2" gate valve is very X.

Hmm.. Good idea.. Will drop by hai cheong to check price.. Thanks bro! Sent from my LT26i using Tapatalk 2

can replace the L with flexible hose too

[zonerx]

another way is block the water flow at end of the pipe and wait for overflow box to filled up then let go, the high volumn of water will push out all the air in the pipe

[zonerx]

another cheap way is add 2" to 1" or 1.5" reducer to end of your outlet pipe

[DeadmanZ]

Hahaha .. thanks bro for so many solutions, i've tried blocking the output but when i let go, it suck in the air again ...

maybe will try a 2" to 1" reducer for the cheaper alternative first... thanks bro!

[zonerx]

any update? problem solved?

[DeadmanZ]

Haha.. Update is.. I stuff the cotton wool very high.. Until touching the tip of the output.. Then noise reduce a lot.. But will have to monitor the wool.. If not choke then going to overflow from sump.. Sent from my LT26i using Tapatalk 2

Bro, I facing the same problem as u. Solved the problem by adding in a valve. 99% sound cut.

Hi Bros,

I designed my overflow as Herbie style overflow with 2 outlet stand pipe and installed the ball valve at the outlet pipe from tank to the sump.

Although Herbie style worked very well, I still need to adjust ball valve when it is necessary.

So, I agreed with Bro megacue concept and it could be serve with safe and ease for you.

Happy Reefing in Dead Silent !

p.s . Dear reefer guy, May I know where can I get that Maggie Muffler locally ?

[DeadmanZ]

Wa.. Thanks bros for all the suggestion.. Appreciate that.. I guess for my case.. Is only to add a valve at the outlet.. But my concern is.. If we restrict the output.. But return is still pumping in the same amount of water.. Won't the water level raises? Or worst still.. Overflow out from dt? Sent from my LT26i using Tapatalk 2

It should be fine, if you can make your timing to adjust the valve. And what is your water level from the edge of your tank?

Mine is just 25mm away from top age and that is the reason I designed two over flow stand pipes to be get the stable level of display tank water.

If I don't want to drain the water from second stand pipe, I have to adjust my valve two times per week.

Hope my info will help you

[DeadmanZ]

What do u mean by adjust the valve 2 times a week bro? Meaning every time you have to increase the flow to lower the water level.. Then lower the flow back again? Like that sounds risky lei.. Hahah Sent from my LT26i using Tapatalk 2

Get a gate valve which gives you very precise adjustment... Herbie method is proven to work you just need to moniter and make sure that the water level when you first change to herbie, and for herbie, it is best to have 3 overflow pipe, 2 main overflow and 1 emergency overflow, if you have 1 overflow then you need to be extra careful..

Thanks Terryz- for your helped.

I used Filter Sock at Main Drain Pipe, then I have to change it twice per week since it was block every 3 days.

When the filter sock was block, the water level inside the over flow box is a bit high and the second drain start working.

I installed the Second Outlet above the water level of sump to hear the sound when water start coming out.

Then I adjust the Valve at Main Drain to reduce the outlet flow, If i'm not able to change the Filter Sock.

That's why I mentioned about the timing to adjust the valve in my previous comments.

You are right it is quite risky unless you installed Complete Herbie method with 3 stand pipes.

But you still have to adjust it once when you do water change.

Hi, would like to know where to get the maggie muffler too..
