Black Tank Grey Tank

[HATCHET19]

I own an older 2004 Georgetown 326DS. I have owned it for almost 7 years. In the last year or so I noticed my Grey Tank/Blank Tank storage seems to have changed a bit. First, my Black Tank flush stopped working...I think. So experimenting a bit I have noticed that my toilet, kitchen sink and bathroom sink empty into the Black Tank. And only the shower dumps into the Grey Tank. Any idea what might be going on? Tanks dump just fine. We don't really use the shower. So after a week of camping the Black Tank is full and the Grey Tank is almost empty.

I wish I had that problem. With two adults the 52-gallon black tank lasts about five nights (with just a very limited number of trips so far) while the 52-gallon grey tank fills up in a couple of days.

I'm putting my digital water flow gauge on the city water inlet at the beginning of the next trip so I can see what is using how much And who is using how much.

I timed the stock FR shower head and it takes 2:30 to fill a 2-gallon bucket off the water pump so that's probably not it.
