Were new to campers with bathrooms.   My question is why is the Black tank so small?  We are three and can fill it up in a day, are we doing something wrong???

You don't give the model and year. I think they've changed it recently, but it used to be that the sinks on a 199 drained into the black water tank. The graywater tank was only for the shower.

sorry,  I have a 2017 199 fkp

I belive your right about the sink.  That still does not answer why the black tank is so small.  I looked it up on the mother site and the black is the smallest holding tank.....I think it needs to be the largest holding tank.

Looks like a 17 gallon black tank and a 49 gallon gray. Our 177 has 10 for black, and will last 2 of us 3 days. But, you learn when you've had to live with a 4 gallon cassette toilet with 2 adults and 3 kids in a pop-up. Yellow flush is a pedal push as quick as you can. Fill a little bit before brown, and that flush isn't much more.

Given what you've got, washing dishes should be no more than a once a day thing - a sink full of water is probably 3 gallons. Paper and plastic might be useful. Yeah, it's a poor design to have your sinks also go into the smaller black tank. Look at the bright side, you can take lots of showers - your gray tank is larger than your fresh tank! [thumb]

If you stay at camps with dump stations, you might want to look into getting a tote tank, which will let you dump without moving the camper.

My '17 199 with two people is about 2 days on black. The galley is my problem tank. Wife is borderline OCD with the hand-washing. 😕

177 here with 2 people. As mikes said, we are good for about 3 days with the black tank. You just have to be aware, however in your case poor design plays a big roll.

Also,, don't trust the on board level indicator in your camper. Those black tanks notoriously give faulty readings due to toilet paper, etc.  If I want ours to fully go back to empty on the indicator, I use either a hose attachment on the outtake side to spray water up into the tank, or a wand on the toilet side to spray down into the tank.  I prefer the wand as it allows me to watch the water enter the toilet from below and therefore know it is as full as possible.  Usually, doing that twice will get the tank completely empty.  Without a good flush out of the tank, you will get full readings on your indicator quickly an they will not go back to empty after dumping.  Other than that..yes, the earlier models of the 199s had the problem with the shower going into the black tank due to the kitchen being in the front.  I hear they have changed that in the later models.

Actually, it was the two sinks that went to black. The shower has always been separate. in the 17's and beyond, bath and kitchen  sinks go to the Galley tank, toilet to black, shower to grey.

Guys;

We have a rule. If it's yellow let it mellow - unless we are traveling down the road. If it's brown, flush it down. Putting "floaties" into the urine prevents skid marks and uses the urine to flush the feces into the tank. Also, use short flushes. Really helps out a lot with slow filling of the black water tank and not wasting clean water. Have to also agree with the black water fill sensor - very inaccurate because of toilet paper. One fellow recommended putting used toilet paper into a separate sealed container which got dumped into campground trash. Sensor becomes more reliable.
