Every time I try to hold water with a obstacle, it leaks out. Here is one example I have made.

Water leaking through bowl

The shape has no holes, and the water is partially contained but slowly leaks out. This has occurred every time I have tried this. What could the cause be?

Setting the obstacle's volume initialisation to shell seems to have fixed it

I have no idea why this works if anyone knows why please add it to the comments.

    The other solution would be to make the walls of your obstacle thicker. If you need to render with thinner walls, then have two meshes. Simulate with the thick-walled one and render with the thin walls. – Fweeb Dec 16 '13 at 14:02

    Is it possible the normals on your obstacle were messed up? – gandalf3 Dec 16 '13 at 23:13
  • @Fweeb the walls of the obstacle where prity thick, changing the thickness didn't have any effect. – Qwertie Jan 16 '14 at 09:08
  • @qwertie They don't appear to be particularly thick in your screenshot. Also, sometimes it helps to apply any Object mode scaling (Ctrl+A) on obstacles before you simulate. – Fweeb Jan 16 '14 at 13:59

For me it helped when I applied Surface Thickness to the obstacle.

I tried running water through a pipe and I changed the time scale to lower and the axis direction to a littler lower and it seems to flow perfectly no leakage but still maintaining a good amount of water flow

Try to apply modifiers on your obstacle, especially Solidify. Fluid seems to leak when the obstacle's geometry has to be computed on-the-fly.
