Bathroom Sink draining to Black Water tank

[Brockx]

Both of my Fleetwoods were toilet only to Black tank. I have heard of lavatory sink going to the Black, but never shower to Black. Wife would fill the Black tank in a New York minute with her shower time.

As most have mentioned, my Adventurer bath sink went to black tank and like someone else said, we would use kitchen sink most of the time when out dry camping so not to fill black tank up too fast. Not sure why these are plumbed this way but so be it.

Just a guess but that Mfr. may have felt mouthwash, toothpaste, shaving residue, etc. was better served going there. The grey tank always seems to fill fastest, probably not a rare event for grey water to hit the ground in some boondock situations.

That is by design/purposefully. Being stingy with flushing water has caused many clogged black tanks.
