Loud Overflow ???

yachtdr22 · 07/05/2018, 12:28 PM

Greetings all,
I have a loud overflow and I am looking for ideas to quiet it down a bit.
This is a condition that I have overlooked for years and I'm ready to maybe do something about it.

Thanks in advance!
Drew
Trying to figure how to upload a short clip of it??

I can't see whats inside the overflow box..
Just open bulkheads on the back wall?
Getting a gurgling/flushing noise?
Excessive bubbles at the outlets of the drain pipes (in the sump)

Have you tried throttling down the return pump (valve on output of pump to slow the flowrate) to see how that effects flow?
What size pump are you using?

Open to changing the overflow box to incorporate some elbows in there?

Gurgling and flushing
I have tried different valve alignment on the DRAIN side. Return only has check valve.
Overflow is an open box with drain on each end.
Excessive bubbles?? see pic?

Im not sure if the pics are good enough?

I will have to tear through my old build sheet for the pump specs, but it also drives a Carbon Reactor and a GFO Reactor.
I also have 2) Vortech MPH-40's and 1) MPH-10 for circulation
I was trying to figure out the specs on my return pump and have to hang my head in shame as I cannot... Pump is due for a cleaning so I will figure that out soon.

yep... too much flow for your current setup..
Without redoing the overflow box and incorporating elbows your option is really only to throttle back the pump by placing a valve on the return line and closing it until the noise is tolerable..

That overflow setup is just plain inferior..
In the future look into a bean animal setup..

See the elbow setups here.. If you can get to that then you have a chance..

Thanks....
I am going to see what it will take to convert
I have a "Low Sump" alarm that I can set to turn off the return pump. (I love my Apex) and not have the "Emergency" line like it WARNS NOT to omit!
Do you see a easy way to quiet it down a bit? I dont want silent, but i think it's time to turn down her volume a bit?

Thanks again,
Drew

As stated above the "easy/quick" way is to just throttle down the return pump..
You are just flowing too much for that overflow setup.. plain and simple..
Throttle down with a valve on the return line and you may be happy enough with that..

It wouldn’t be hard to turn it into a syphon drain, basically a herbie. All u would have to do is add a 90 to the bulkheads inside of the overflow box with one facing up & one facing down. The only other thing u would need to do would be cap off the tubes for the air inlets on your 90’s. U already have the valve in place so that would be all u have to do. Then u would be able to handle the flow u have now & it will pretty much be silent.

The only other thing u can do is turn down the flow like mcgyver mentioned. With the size plumbing u have I don’t think u will be happy with the flow for how much u will have to dial it down for it to be quiet. Plus, it would be harder adding a valve to the return then it would be to just turn it into a herbie with a syphon drain.

IF you decide to try the Herbie Drain you will have to change the siphon drain line valve to a Gate Valve for fine tuning, which is not easily achieved with a Ball Valve.

Talk to the owner and engineer of exotic marine systems in Texas. I had a back drilled tank and Paul was able to take my measurements and build a custom ghost overflow to match the bulkhead drill holes that existed. He even sent a test template to confirm fit before he built the boxes. I am running bean animal in the outer box and it is silent. All was very affordable and well built www.exoticmarinesystems.com

It was problematic to put a valve in the Discharge of the pump, so I added another port to my discharge manifold that supplies water to the 2 reactors, put a valve on it and is now free flowing which is reducing the volume up to the tank. it had quieted down some.

I appreciate the feedback!

Thanks for the idea... Im not sure i can do that with my current overflow??

U will have to be able to place a 90 into the bulkhead inside of the overflow box. Turn a 90 facing up for your emergency & one facing down on the other bulkhead for the syphon. U may have to use a street 90 & cut a little off the spigot end to make it fit. The only other thing u would need to do is cap off or plug the airlines on your existing 90’s so u don’t allow any air into the drains. Any drain that allows air into the pipe will only be able to handle a certain amount of flow until they get loud. The smaller the pipe the less flow that will be.

I dont think you can do a herbie. Looks like a glass holes overflow kit. They work but are noisy.
