F cannot fill up because D must completely fill up first. J cannot get a drop of water until D can bear no more, and C is allowed to fill up to J.
F cannot get any water until J is filled, so F can't fill first.
A drips to B, drips to C, drops to D, drips to G.
G fills up, then D fills up, then C can finally start filling.
Only if the system is pressurized, or the mass of the water is sufficient, will F, H, E, or C ever be filled, simply because they don't have a pipe which enters their volume at the top.
Edit: Hot damn, there are blockages. I thought those were just graphical, not part of the puzzle. Silly me...

L will fill first, then.
D is blocked...so it cannot fill up at all. So D, G and E are useless and will never fill and neither will H as it too is blocked.
Yeah, I'm thinking L now.
L is too high. F and all the lower tubes will fill up before L fills up.
F can't fill up unless there is pressure in the system.
Water can't drip up.
