The reason is real estate inside the tank. I find that to be invalid as it is only several inches at the top of the tank, unusable real estate. Some worry about light loss, but there is plenty of light as the physics of light in a liquid are different than in the atmosphere...(well not exactly) pretty much a lot of do about nothing. Shoving the system into small external boxes, and small internal overflows, simply defeats the efficiency. IT is a complete system. These modifications take the technology backwards. E.G. long flat weirs back to small toothed weirs. For the most part I suspect it is just misunderstanding how it all works together, and why.

The system is fine as designed, and also when "modified within certain limitations" functions as it should. Problems occur, when aesthetics, or convenience overrule the basic design criteria. Hence a 1000 opinions about a system that is very simple and straightforward... and the seemingly unending revisiting of the same mods/problems/solutions time and again...
You know, I'm not really following what you said there Just wanna know if there's any technical reason it won't work.

Hi guys,

Does anyone have any plans or measurements for a 5x2x2 using a coast to coast external overflow with BA to sump. Specifically the overflow and BA specs.

I am getting a custom tank built soon and no one in my local area knows what a BA is, whenever I ask all I get is a blank look with a really confused look on their faces and they think I'm insane! Then they just try to sell me an off the shelf tank.

So I really need to give a tank builder plans of exactly what I need so they can build the tank.

Is there anything around that I can use to give my tank builder?

It's going to be impossible to get full flow through a pipe with air trapped up in the top of it.

There are many reasons a pipe may occlude, and it is a combination of these things that make a single failure point a poor practice.
Which is greater, the odds of a 1.5" blockage or of a 1? blockage?
When the cross sectional area of a 1.5" pipe is more than double that of a 1" pipe, I'm more than doubling the amount of blockage it would take to have a problem. You're counting number of pipes, instead of figuring how much area would have to be blocked. More isn't necessarily better.

When people tell you it "won't work" they are right: it will not work as a BA system is supposed to, because it is not a BA system, rather a two pipe system, more inline with Herbie... in the context of this thread, a BA has 3 discreet pipes; redundant statements to make it more clear what "It won't work" means...
It has three pipes. I don't know what "discreet pipes" are though. It is based on the principles of a Bean Animal. A copy? No. It DOES work, and it works well.

Air will continue to be drawn in through the open channel. The air intake will increase, due to increased water flow down line, and make the system more unstable: more air = less water.
The original post by Bean Animal says:

"The design criteria:

1) Dead Silent
2) Set and Forget
3) Limit Bubbles in Sump
4) Failsafe to Prevent Floods
5) Easy to Clean if Needed"

I have achieved all of these. Testing of my setup has proven it works. It works silently. My intent was never to mimic somebody else, but make something that worked the way *I* wanted it to, and for my needs.

BTW, if you completely closed your siphon line (simulating a 100% blockage), and the open channel took all the flow, it wouldn't keep a siphon for long. If it did, we'd not need a valve in the siphon line to keep it full.

Smile BeanAnimal drain with long horizontal run

Just checking to see if anyone has experience with a BeanAnimal drain to basement sump with a long horizontal run.

I am shooting for 1400-1500 GPH flow with 12' vertical drop and 27' horizontal. Total of 3-90's (using sweeps) to get from overflow to sump. I am planning on using 1-1/2" pipe, about a 3-4" slope towards the sump on the horizontal section and gate valve at the sump.

Any thoughts or experiences out there with a setup close to this?

Thanks

If the "horizontal run" is angled down, there is little likelihood that there would be a problem. However, the friction losses in such a long run, will reduce the flow capacity of the drain line significantly.

You can get the flow you want with that setup, but if you can increase the size of the drain pipe to 2", you'll be better off in the long run since biofouling will slow it down a bit over time. I have a 30' horizontal run with 5' of drop. Using 2" drain pipe with 6 sweep els. I have plenty of flow to support 1500 gph +. I run 1300 gph (measured with the apex flow meter) and have the drain valve closed more than 1/4 of the way.

When I first set up my tank I ran 1.5" drain pipe and within a year it was having a hard time keeping up with the return pump. My guess is that it was draining around 1200 gph max.

Your 12' of drop will help substantially and you probably will get away with 1.5" pipe, but I'd go with the 2" for the extra headroom.

I do not recall mentioning anything concerning "full flow" in the discussion of the holes in the top of the siphon. My post stated they are unnecessary for the system to function properly, when the system is constructed properly.

Quote:

I don't either. Typos cause confusion quite often. The correct spelling is

"discrete"
adjective:

1. apart or detached from others; separate; distinct.
2. consisting of or characterized by distinct or individual parts; discontinuous.


Quote:

No, it is not based on the principles of Bean's system that consists of three discrete drain lines. Your system has only two discrete drain lines, therefore the design principle is based on what is termed the Herbie drain system. Despite the fact that the top end of one of the pipes splits in two, the discrete function of those joined pipes cancel each other out, and do not follow the BA design.

Context. You are using information that is out of context with the nature of my post.

That is fine, but indeed you did mimic countless people that have tried this before. However, this thread is dedicated to one system, and one system only. That is the design published by Bean Animal. There are probably at least a 1000 ways to construct a drain system that "work." A claim that this is the only way to build a drain system has never been made. That is not the point. What you built, is related to the Herbie, (only two discrete pipes.) Your "want" was to only run two pipes to the basement, rather than the three pipes required with a BA. OK, fine. But this is not the first time the joining of the standpipes (whether it is all of them or only two of them) has been brought up. Nor is it the first time, it was criticized.

Quote:

Well first off, if the siphon becomes 100% occluded, the dry emergency takes the flow. If subsequently the dry emergency plugs, the water level rises, and trips the open channel to siphon mode, by occluding the air vent line. At that point the water level would be sufficiently high for the open channel to maintain "siphon" long enough to lower the water level (often pretty quickly due to the head height.) After that, it can only be expected to behave as a Durso that has too much flow in it, because that is exactly what it is.

Again, your system short-circuits the first safety feature, because the dry emergency can only function as an open channel, until water level is high enough to stop the flow of air into both the dry emergency and open channel. It violates the basic safety rule for running siphons: never run a siphon without a dry emergency, exactly in the same way a Herbie with a so called "trickle drain" does. In the end that is all you really have.

As for your dismissal of the single failure point in your system: they said the Titanic could not sink. What were the odds? The engineering was not well thought out enough, and the Titanic is sitting at the bottom of the Atlantic Ocean with 1200 souls aboard, 300 pulled from the water the next day. What were the odds of the Challenger exploding shortly after launch, considering the multitude of redundant fail safe/backup systems used?

It is great it works for you; and it is great that it meets your specifications. However, for this thread, it does not meet the specifications; and I have explained why twice now. Bean, myself, and a couple others, have explained it at least a hundred times prior to this. This thread is too assist those wishing to set up a BA system the correct way, and such discussions of system that deviate far from the BA system, only serve to complicate the topic for those that are unfamiliar, and those that know just enough to be "dangerous."

So i've come up with a rough design for my new build.

Can one of the experts here that has done this before take a quick look and see if it looks OK or if something is wrong with it. I'm open to ideas and improvements. I'd rather get it right the first time as it can be expensive making changes after.

Thanks in advance!

Photobucket wants you to pay $400/year to be able to hotlink pics here. Use something else, they suck round objects that dangle between a man's legs now.

Lets try this again! Ill get there eventually.

Any comments on the design would be greatly appreciated!

It's YOUR opinion of determining what HIS basic principles are. I don't care if you call it a donkey. I really don't care. Please quit embarrassing yourself. Please, go argue with somebody else.

From the looks of it, it appears that you plan on having the DT feed into the overflow with a "shortened DT"? A little bit like an infinity edge pool?

If that is the case, that doesn't sound too great. Whilst, the water will get into the external overflow box, what about wandering fish and whatnot? That is a critical function of the weirs on the overflow boxes. Sure, you will get maximum surface skimming, but it would come at that cost.
