I don't think it will have much effect on how the water flows from the pipes, but I've only had one cup of coffee so far today.

Picture this: What if you installed your bog pipes completely vertical. Slits from top to bottom. As you pump water into that pipe, what happens? It will depend on the size of the pipe and the size of the slits, I guess. If you have a small pipe and small slits, you will have high pressure. Water will come out of the bottom first, but as the pipe fills up due to back pressure, it will come out all the slits. If you have enough pressure and small enough slits, flow out of the slits will be pretty even across all of them. If you have a big pipe with big slits and low flow, all the water will come out of the bottom slits and the top slits will always be dry.

Does any of that even matter? I guess that's what you initially asked. Probably not much. I guess if you're not building any way to backflush your bog you may end up clogging the lower portion of your bog before the rest. But, again, depends on... oh gee why am I still typing.
seriously considerring your idea, the first thought is that with verticle, the push force is going horizontally and that would mean bypassing some of your media as it would NOT all start from the bottom. So, for that reason alone, I'd think you'd get less efficiency/efficacy.

BUT! that was a fun read, @combatwombat !!

Mine was not totally level, it caused no issues. The pea gravel I used just filled any of the voids. I did put extra liner under the pvc pipes
Yours is full of just rock, correct? I'm seeing so many wetland filters with milk crates, aqua blocks, etc. I was planning to just do the pipe with rocks in graduated sizes -- cobbles to egg rock to pea gravel. Is the void space necessary? My bog excavation is sort of elliptical in shape, due to the ground in that location. I don't think the small aqua blocks would fit in there that securely but I could probably make it work if it is really beneficial. I'm not planning a re-do - but wanting reassurance that I don't need to! ;)

I have rocks!!!!! It is still kind of hot here so I am going to finish a few indoor projects this week. Next week, it is going to be more pleasant and fall-like, so I will probably get rockin' and rollin' then! :D
