it is supposedly a fixed thing but with the newest versions for 1.7.10 (via curse/twitch desktop app) the rotary condensentrator reffuses to imput water through any form of pipe (and i did try quite a few of them) but whatever i try it doesnt work, even deinstalled mekanism and reinstalled, crafted another one, placing it in different ways etc, and that just breaks the automatic part of things :(

also i just noticed that if you put a portable tank (thermal expansion) into the bucket slot, it fills the machine with water without draining it from the tank

1.7.10 is no longer supported, but regardless, this has been fixed.
