Heads inlet/outlet

[Phil23]

Needing to re plumb heads which going to involve new thru hull fitting and working with limited access/room may sound like a silly query but what would you consider minimum distance from toilet inlet to outlet.

Good question, you don’t want to recirculate the outgoing with the incoming. If you are underway it should not be a problem if the output is further aft than the intake. Just a guess, maybe a couple of feet for when you are not underway. Just a guess though.
