continuous siphon

[Montaquelaveist]

Okay guys and gals i have a question i set up ATO for my sump using a 23 gallon thin blue recycle bin the ones you get at home depot and I'm using a Mag 7 to pump the water its hooked up to a JBJ ato unit my problem is the system works fine but i noticed that after the pump shut off i still had water flow not fast but more like a siphon can anyone tell me how to stop this siphon effect as until i can solve this i can't leave the system connected please help me guys oh yeah the sump is on the same level as the fill container

i had the same issue, i had to make sure the line that goes to the sump is above the water line limit. took me a bit to figure it out but after i did that, no more issues

sump ato layout

here is how mines is setup and the line never sits in the water in the sump so I'm stuck guys click on the link and see a 3rd grade level drawing lol

The output tube has to be raised up higher than the ato tank

it is higher it lifts about 4 inches above the ATO tank should it be higher

or put a elbow that will rise above and leave open to break the syphon. if there is a downward aim of the line going into the sump you will get a continous syphon and water will continue to pour out

there is a downward output but how do i make a break in the line and not get water all over the place when the pump cuts on

Tee off the line, one side goes to sump and one side raised above ATO reservoir.

so when i do that won't the other side push out water as well and how will that affect output

What i like recommending and the easiest way i can relate is is use pvc to make a rain gutter going into the sump. The top of the pvc going into the sump needs to be higher than the ato container. The output from the mag 7 goes into the pvc. The bottom of that output also needs to be above the ato container water line. The gap between the ato output and pvc gutter create your siphon break and the pvc "gutter" prevents water from spraying everywhere.

i would use a much smaller pump. an aqua lifter should work. if something sticks you'll have a flood in no time with the mag.
the discharge of the output line has to be above the water level in the ato reservoir.

I run an aqualifter, when it's on it'll output to the sump first before it reaches the other end.

Others have given great feedback. The water will continue to siphon until the level of water in the ATO is the same as the sump.
I'm curious why you're using a Mag7 as an ato pump. That thing is a beast at 700gph. And that's a disaster waiting to happen.
There are many ways to tackle this, especially with breaking the siphon. But here's a thought, can you just run the output to the DT since it's higher? This might not be a good idea since it will take a bit longer for the level to rise in the sump.

+1 on aqualifter I used to use a maxijet 1200 and I find the aqualifter to be much better. It puts topoff in much slower and there is not as much on off cycling as there was with the larger volume pump

 

[Paolissimo]

Maybe I am not understanding the question, so I apologize in advance if my suggestion doesn't apply, but wouldn't a check valve fix this siphon issue? Also I would think a maxi jet pump or a similar small pump would be more appropriate for an ATO.

 

[Montaquelaveist]

okay so i will try and answer the last three questions best i can
1- the reason i use the mag7 is because of the distance from the ATO container to the sump i tried the smaller pumps and they just weren't working that well, and i can't run it to the DT due to the fact that my filter room is way too far from the DT

2- I'm also using the Mag7 because I'm about to get a barrel and put a bulk head on it and use the pump on the outside so this is why everything is right now PVC

3- as you can see in the picture slightly lol the return is much higher than the container but yet i still get a siphon from the ATO to the Sump

so what i was thinking is if i drill a small hole in the pipe thats in the ATO container would that break the siphon once the pump shuts off is would be right above the water level and i would angle down into the container so any water that sprays out will just go right down and i was thinking that once the pump is off there won't be any pressure so the siphon would be cut due to the air it sucks in what do you guys think

Keep the ato water level below sump level and keep the discharge line out of the water in sump...

i can't do that because the sump and ato unit are in the same room and on the same level

The tubing on the sump side must be higher than the container for it to air break. In your picture your container is taller than the sump so what you could do is either run the tubing up high or take a piece of pvc run it up the sump higher than the container and stick the tubing in that , that will create an air break.

thanks i will try that
