Okay, so here's part two of Rerouting disposals to the HoP's office, Meta Addition.
I finally got to play a round when it rolled Meta, and after a bit if fiddling, i managed to re-rout the entire system to HoP's. This one is a bit tricky and will require an RPD. Luckily meta has a public autolathe by default, so after a bit of hacking, you should be able to acquire one.
The junction for for disposals is located just below reclamation and a little to the left
In order to fully re-rout it, you're going to need to do a little bit of deconstruction, then build three bent pipes.

(there is a third bent pipe underneath that wall, i was too lazy to deconstruct it again)
Then you are going to need to build a long line of pipes from there to the HoP's office
If you've done this on Box, then you should already have a good enough idea of how to switch out pipes. Then you're done!
greifprank the HoP to your hearts content!
that's probably going to be it for a while on rerouting Disposals to the HoP's office, since map rotation only really chooses Box/Meta (thank god) anymore.
