A.C.E. 29.4 black water fills up

Unit: 2018 A.C.E. 29.4
I noticed yesterday that something other than the toilet and saniflush system is dumping into my black water tank. One of the sinks or shower is definitely connected to the black and not the gray. This wasn't the case with my old class A, and it explains a lot. I've been wondering for the last 10 months why my black water fills so quickly.

Does anyone know which drain is dumping into my black? I want to avoid using it to conserve space.

Bathroom sink on my 29m goes to the black tank. Most likely your does also

Thanks for the info. It'll be easy to verify now that I know where to look. I'll just open the gray drain, run the water in the bathroom sink, and if nothing comes out, my A.C.E. will be the same as your Hurricane. Thanks again!

In my 2018 ACE 32.1 both bathroom sinks are plumbed to the black tank. Kitchen sink and showers are plumbed to the grey tanks.

Bathroom sink in ours goes to the back tank, too.
