Modifed Herbie Drain

[Hudzon]

I have a single drain utube style overflow and my sump is outside of the stand so I am trying to get it quiet, would this work as a modified herbie style drain ?

I doubt the emergency could handle the flow without the external overflow box overflowing.

You need water height to overcome the friction loss of all those 90's probably a few inches flow and pipe size determining.

Two holes in the box would be easier and safer.

Will it work? Probably. Is it safe? No, as it presents a single point of failure, that cannot be failsafed.

Ditto, although the emergency is probably useless anyway. Whatever is going to clog the herbie is probably going to cause problems with your u-tube. My suggestion would be to drill the tank (it can be done with livestock in it).

The u-tube is also a non-redundant single point of failure.

GRRRRRRRRRR...... I was going back to edit my post to reflect that. Good call...though I don't think drilling a tank with water in it, although doable, is a very good idea. One slip, and it is all over. Drilling horizontally is a bit harder than vertical, so the chance of an oopss is greatly increase.

I realize it's still a single point of failure it always has been, what I was looking for was would the pseudo emergency drain take it back to the same safety level it was at before adding the gate valve.
The tank will only be up for a few more months as my new rr tank is sitting on my porch waiting for painting and carpet to get finished.

Why can't you drill two holes in your overflow box? By the pic you have enough space.

Of course it's better to drill the tank, but two holes in the external overflow box one open channel one siphon will work until you can drill the tank some time in the distant future.

If your new tank is on the way don't fiddle, your more likely to goof something up and cause a flood while trying to MacGyver a quiter overflow. Just be patient and live with it for a couple more months. Turn on some soothing ocean wave background music to drown out the overflow

I've been flood free with my good old hang on overflow for over a decade.......with careful monitoring and cleaning of course.
