Help! Dosing pump back siphoning

I’m having some trouble with my versa pump back siphoning. I have the pump set as the middle man between my ato and kalk stirrer (the ato feeds the stirrer). However when the pump is not running it begins back siphoning . I woke up this morning and roughly about 10% of my kalk was pulled out.
please check out the video to see what I’m saying. I will also post a picture of the set up. The pump pump is about 3 feet away. You can see it in the far right cabinet.

thanks in advance

Assure your inlet and outlet is properly connected. You can simply switch the lines and it will run correct in/out ports

Hey, did you manage to figure out how to fix this? I've got the same problem. i have a new tube as well. I've also tried a check valve howeverr that just stopped it being able to pump up kalk at a slow rate

May need a new dosing head. Could be syphoning.
