3D water flow liquid colliding with 3d objects

Hello all, I would like to resolve my problem, I want to have a water liquid which flows from one tube to another tube, between 2 tubes there are many game objects that water must collide and change direction. I haven't tried "Obi Fluid" https://www.assetstore.unity3d.com/en/#!/content/63067 Can't buy it! I have tried free version "Fluvio Free" https://www.assetstore.unity3d.com/en/#!/content/2888
in Fluvio if I add to my game objects "Liquid Collider" component than FPS goes down (about 7-8 FPS) I also tried to download Fluvio examples like Three, Waterfall but my unity crashes.

I also tried to use Meatballs and downloaded some examples Liquid Physics from here: http://codeartist.mx/tutorials/liquids/ But I can't implement it in my demo project.

So please is there any other solution please. There is a example image that shows what I want to achieve. Thanks in advance
