If the water is flowing without the center of the loop raised (so friction is being overcome), then yes. There are some frictional losses, even with very large IDs, so you may get no flow at all with 1000' of hose. Garden hose comes in 100' lengths, though - try with that.
Offended? Heck, no - I'd prefer you thought I was an idiot, so long as you went out and did the experiment to see how well your mental model of the world and the actual world match. People kept Aristotle's model of gravity for a very long time - IMHO because they either didn't bother to try for themselves or they tried it the same way he did (pebbles dropped through water), which doesn't match out-of-water very well.
