Lemme show you guys my humble version of my DIY overflow from your help. Very Happy Most of the materials been used are excess from previous house renovation and from my moms kitchen.. Very Happy

Here is the the inside box,
it is a 3"X5" office utility box,


The Outside box, a 6"x8" tupperware container


Attached is a blue pvc diy bulkhead


1" dia. PVC diy bulkhead


Plastic bolt & nuts, spare from toilet bowl seat cover. Very Happy


Clear Plastic acrylic, to hold the two boxes.


Blue pvc diy 2x-u-tube (I guess I'll change it to a clear u tube for easy viewing if bubbles accumulate at the top)


Heres the result, simple and affordable yet reliable.


Top view

I tested it and I'm satisfied with the result. except with the u-tube, much better if it clear so you can easily check if theres bubble accumulation at the top.

And here is my realiable back-up if ever siphon break to that u-tube.

it's a 25mm dia. blue pvc water pipe.


I've notice that having too many overflow running at one time is not really a guarantee that you won't flood your carpet once one of the two breaka siphon
It is because your return pump have been fine tuned based from the water the going down to your sump. once, any of two broke a siphon then the water from the display tank gradually going up till' it get overflowed.
So I set the other overflow as a back-up and set it a bit higher from the other overflow. what an experiment. yet successful...

Very Happy Very Happy Very Happy
