Over flow very noisy

[tjlee]

Dear All

Just set up a new system yesterday

Everything run well except the overflow is very noisy.....sound like waterfall

and sometime air ###### sound

Need help, else my wife will score as too lound until cannot sleep.

Could it be the return pump too strong?

thanks

durso pipe......

I think the return pump is slower than the water flowing down the overflow

[reefer guy]

couldnt bro, coz whatever water volume the pump returns to the main tank will be displaced to the overflow accordingly... any imbalance would end up with the main tank over flowing or the sump running dry....

[xersion]

is the overflow pipe straight down to the sump? maybe u can try posting a pic

[Limpc]

Durso is the solution, bro.

No more complain from my wife, ever since I DIY-ed for both my tank.

[tjlee]

Thanks for sharing....

May be i should invite Bro limpc for supper over my place to diy for me....hee

will try to do something tonight...if cannot solve...will cry for help...

[Limpc]

Sounds like a plan to me !!!

Then my wife will complaining I snore too much after good supper from you.

Do you have a valve between the sump and the drain pipe? Tunung the valve may eliminate the air ###### sound but the waterfall noise is another matter.

Instead of the direct flow through pipe, he connect an inverted U-pipe, so water flow from below-up! understand? sorry do not know how to post photo yet...

you are welcome to see at my place..... stay in hougang

Sorry to tag along, but for external overflow box users, with 2 return holes down, = 2 ball valuve , box too small for a durso , and valve is diff to control, a little off , suction sound produce, a little closer, the water in box will be at brim.. any suggestion? Thanks, sorry to tag in.

i was using a dual pipe overflow box in my first ever tank and this 'durso' helped me with regards to the space constraints in the box....hope this helps you...
