[aStRoBo|]

finally made up my mind to DIY one overflow box after very unhappy with my overflow pipe. so here goes.. sorry for the quality of pic, hp cam only..

the box in the tank..

[aStRoBo|]

water in..to the two siphon pipe..

[aStRoBo|]

outer box.. which draw water down to my sump..

[aStRoBo|]

SaltWater: "Oh no, i'm flowing down!"

[aStRoBo|]

Ball valve, very useful to control the flow and the noise produced from the siphoning..

Tat's abt all.. used the whole afternoon to complete it.. cost total less than $30..

woo.. held together using cable ties? strong?

[rainbowdarter]

very simple....and working...

Nowaday, a lot of cheap plastic boxes

selling @ affordable price, sometime come with

different shape and length...only need creativity to

make use of them.....really love DIY.

cable tie? nope, use two 'suckers' or 'stopper' and clip my "U" tube onto it, to stable it lor. As for the outer box, uses plastic "S" shape hook and the pipe below the box is siliconed to support the box too!

ya lo, just tat those selling outside are more professionally done and neat finish. But it also occupy space in the tank too.. so as long can use can le la.. save $..

Anyway good try...at least not like mine.

Currently using seperate internal overflow unit with small pump about 1200l/hr

pumping down overflowed water from main to sump. Thought of DIY slim but more depth overflow box, not sure can work or not.

If I off the pump. the flow not really fast. Maybe due to the size of the pvc pipe that I used. I think it 1 inch OD.

outer box.. which draw water down to my sump..

Hi aStRoBo|,

The inner box seems quite shallow and the two siphon pipes are quite short compared to the outer box and pipes. Have you tested the siphon should there be power failure? This problem may cause disaster when the power resumes after a power failure.

Just sharing...

yup. no prob with tat. when power off, the return pump starts to stop flowing water into the innerbox, without water getting into inner box, siphon stop. Den follow by my return pipe of my return pump will suck the water down to the sump until it break the siphon where i drill a hole onto it.

Will the siphon auto start again when power resumes?

nope. but the volume of water in my sump tank is enough to be filled into my main tank.

I think this is not right. The siphon *should* continue normally after a power loss. U might have a tank which can accomodate all your sump water but this is not what we ultimately want am I right? You might want to take a closer look to your o'flow design.

Your outer and inner box should be roughly at the same level. In a power failure, both the U tube ends in the boxes *must be submerged* in the remaining water to maintain siphon. Please note the critical depth between the standpipe opening and U tube opening in the diagram - this is the key to maintain the siphon.
