Buried? Hydro?
Remeber that the CAESAR II buried pipe modeler is designed to ignore deadweight loads in the buries sections. Take a look at your densities in the buried sections. They are all zero. CAESAR II has point supports, we cannot directly model the continuous support of the soil. Instead we place a series of point supports wherever strain-based bearing occurs. We assume that the soil supports deadweight.
It appears that the supports we use are unable to accommodate your water weight.
If it is important, do it "by hand".
