One week later… No answer… I just looked at your file and I understood why. It’s a total mess in here.
First, you don’t need to work at such a scale. Reduce everything to 10% of its current size. That’s enough. (I couldn’t see everything because of the camera clipping. Insane!) And next, restart from zero. It looks like you applied a subsurf modifer at the power 10… at least. And don’t get me started on the normals. Even Blender can’t cope any more with such a mess. Don’t expect anybody to do such a tedious work by hand for you. So…
Always work with the simplest geometry as possible because fluid simulations are computer-heavy stuff. The pretty and complex stuff must stay out of the way until the rendering.
Sorry if I’m not more friendly but at least you get a (honest) answer.
