DIY overflow

[GrossGraphix]

I have a couple of questions just to make sure there is a reason for this or not.

1. Does the pipe inside the tank have to loop down to bottom and then back to water level??

2. Can you place the T on the outside of tank anywhere as long as it is below the water line of tank?

I would like to make the pipe inside tank as short as possible so not to be an eye sore.

Try like this only 1 pip inside the tank

Is that the way you have yours set up?

I just wanted to run a short pipe into water then do two 90's at water line no pipe to bottom and back up.
I have to drains that go to bottom thought about doin a top one too.

Never mind i found a vid on youtube that confirms what i want to do

I "believe" on the 1st design, that siphon set up is designed to restart automatically should you lose power to the pump and lose the siphon once water get below the siphon break. On the 2nd design, the siphon will not restart on its own. The pump will restart filling the tank, which will overflow. Pretty sure I'm right but I am sure someone else will chime in.

I agree Ross.

However...

1. Does the pipe inside the tank have to loop down to bottom and then back to water level??

No, but the higher the loop the more air will be drawn in.

2. Can you place the T on the outside of tank anywhere as long as it is below the water line of tank?

Yes, but the higher the outlet the slower the flow.

1. No, it does not have to go all the way to the bottom, but the further down the better as stated before.

2. Yesm but further down is better

** also, you will want your outer loop to be lower than the inner to help keep the siphon running a bit faster.

Nfored's design will restart as long as the water level doesn't reach below the inlet. You would have to lose almost all of the water in the tank before the siphon would break. The T would stop the water flow long before you ever got to that point. The siphon should be maintained when the power stops.

ok built it and now it does not restart by itself. Thought i did it all right. Any ideas? Here is some pics.


Maybe the T needs to be up a lil higher so that the flow of water will help pull water and make it restart??

Sometimes when we re-invent a wheel good things happen, this is not one of those times.
Take a look/read through the links below. Should answer any questions you have.

Ok that tells me how to build his. Not whats wrong with mine. As i asked earlier they said the t is better the farther down ya go so mine is at it lowest. So you trying to tell me the T needs to go at the water line??????
