Put the valves on the pump outlets rather than the drain

There are acceptable circumstances where valves on a drain work.
The herbie drain is exactly that.
One main drain with a valve, and an open emergency drain.
The OP has 2 drains.

I understand. It is just not acceptable to me " open " is not a Guarantee for me . I prefer the Bean Animal approach. Not my words and did not want to say this but it is true . A small move on a ball valve results in a very large change. Which is why being a pipefitter I have always said a globe valve is the proper valve for small flow adjustments . They are used on all Octo Skimmers even though Octo calls them something different. I have since stopped mentioning it at first reaction because I think people don't understand the physical function or care to inquire . , so to find one in a small diameter at an affordable price made in PVC is impossible . Acceptable By Who ? My opinion ., verses YOUR OPINION not the great gathering of THEY or Them . So lets stop going round and round . I thought my idea of controlling flow on the outlet of an AC pump which is the cheaper approach is at least a better option than screwing with the overflow drain which is critical. The result of a slow flow from a pump just decreases the over turn rate not risking a mess

By the way I only offer these ideas as a choice to the original poster . If they would have asked about an overflow I would have offered what I consider an entirely different product which states no over flow issues at all . No argument was intended

I'm trying not to argue too.
My idea was to try and convert his drilled box into ( what I would do) a working overflow that will remain quiet long term.
I absolutely agree with you that putting a valve on a single drain is asking for trouble.
I was hoping the OP could utilize the second hole as an emergency drain.
It's going to come down to just adding water and turning on the pump and seeing how it goes.

bean animal for me too

Hi, I am currently writing a book on reef tanks for beginners, would you be interested in helping me review the chapter about coral lighting, flow, dipping and safety? In exchange for acknowledgment in the book, a complimentary final copy and possibly credits by name or username.

Gaskets between the flange and the box and the box and the tank wall is the proper setup. It will be fine and is a standard setup. No need for silicone.

Here is the final setup. The drain is still kind of loud. I drilled one hole at first in the vent cap then just kept drilling little holes but it never got quieter. It stopped flushing but it would still purge air up the line so it was almost like flushing. I might try inserting a small tube in a new vent that goes below the water line in the pipe to see if that helps. Most likely I will just cap it off completely and adjust the drain valve.

I didn't glue the 90 inside the overflow box too, so if I take that out it allows more water to pass through.

Open to other suggestions.

How far below the bottom of the teeth of the overflow box is the top of the emergency drain?

 

[bigjonbird]

I took out the stand pipe in the picture, its about an inch below. I was thinking about raising it up some to where it is about 1/2" below the weir fins, but not sure if that will do anything. It would be shorter than what is in the picture. I tried messing with the height but it didn't help the noise.

The durso 90 that is in the overflow box is cut off so that it really doesn't have much pipe facing down into the water because I can't fit a normal 90deg on there. I had to trim it. I don't think that would make much a difference though either.

Durso's are loud. Not going to be able to do much with it.

I don't know if this is going to be possible, but I think you might be able to convert what you have into a herbie drain.
I would put a solid cap back on the one with the 90 on it.
Close the valve a tiny bit at a time and see if you can get it to just drain water.
You need to balance the water flow so it comes up just to the bottom of the open pipe.

It looks like a clean install. And while I wonder about stagnant water behind the box, it doesn't bother me enough to make changes to the way it is currently installed. As has already been mentioned, I would test for leaks and move forward with it as is.

But I am curious about something else; I don't ever recall seeing a drilled and mounted overflow jutting off of the glass this way.

Is this overflow designed to be used this way?

 

[mfinn]

The only other way I see is drilling a 3rd hole, getting a new overflow box and going full bean animal.

seemed to me he was still concerned about the noise.

I was actually messing around with this some and I think that is the best option.

If I put the valve near the sump I think that would have helped with the noise because air is forming in the vniyl tubing. The pressure at the end would have helped I think. I guess my next tank will have that......lol

I was also worried some about the small gap but it was either that or or silicone the box to the back of my tank which is not what I wanted. I could have made a 3 sided overflow box instead the 4 sided one, so the bulkheads fit flush against the glass but I thought this might be better for some reason.....

Leak test was good. so I am going to install in my house next week hopefully I can get it to be a little quieter. It isn't too bad, but this is my first sump so I am probably not used to the sound.

I'd worry about getting it up and running. You can work on quieting it down later.

Can you post a brief video? I would like to hear what the overflow sounds like.

Here is Both from BRS with valves . Again I think this is old school which I don't agree with.

agree with ie using valve

Sorry something wrong I pushed the wrong button. I would still use valves on the pump to control flow. It appears they are using the full flow of the T and it is using the full hole for a siphon break
