Silencing beananimal overflow
 

Hello
I have an external overflow the height of my tank with a beananimal style overflow. Tank is located on the main floor and drains via many feet of horizontal and vertical runs into a basement sump. All pvc pipe diameter, drain and return, is 1.5".
It's fairly noisy and the only way to quiet it down was to dial back the return pump significantly. Would this negate the purpose of returning cleaned water to the display because the return is so low - returns are located by the overflow.

I don't believe that it's running as a true beananimal due to the long runs and maybe the height of the overflow. Would shortening the overflow maybe help? Any other thoughts and advice are appreciated.

pictures please

You don't want to be running long horizontal lines, especially if you used 90degree elbows

Where is the noise?

When you say you must crank the flow down to reduce noise then that sounds to me (har har) like maybe the water level in the overflow is too low and you're hearing the water falling into the overflow??

If the noise is coming from the pipes - gurgling? - then there is likely air caught in the pipes. Horizontal runs will do that because it slows down the water which allows bubbles to collect.

How much horizontal distance is there from where the water exits the tank to where it enters the sump? How far under water are the drain lines submerged?

Let me know what part of town you are in, might be able to swing by and give you a hand.
Thanks,
Bob

Sorry no pics art his time.

Couldn't avoid the horizontal lines, have roughly 15 feet. Isn't completely horizontal, had it gently sloped and drains terminate about 4" into filter socks. Also used 2 45's vs 90's where I could.

The noise is definitely coming from the pipes.

Bob I am located in south west off the henday. If you could that'd be so great.

I'm out of town for long weekend but will be back early Monday. Maybe we can find time to have a look then. text me if its easier.

Where in the system is the gate valve? Close to the tank or close to the sump?

Yeah, that too.

Is it 15 feet continuous horizontal or does it make some down steps along the way?

How many gph going through the lines?

The noise is surely from air in the pipes. If you don't have enough flow for 1.5" pipes that could be contributing. There has to be enough velocity to keep the air flushed out.
