Question Black Tank leak or filling with water

Hi all,

I have a 2015 Cedar Creek Cottage, 40CCK and I am having issues with the black tank. We came back after being gone 4 days and the black tank
was full to the point when you tried to flush the toilet, that is where the water level was. I drained the tank, disconnected the tornado line to see if somehow that is why it was full.
They tank still seems to fill to 2/3 daily and it is just my wife at home. Is there another way the water can get into the black tank without flushing the toilet?
Second issue, the underbelly between the axles was full of water, by the smell, it was black water. I pulled the underbelly plastic covers, pulled down the insulation so I could see underneath. There seem to be a very small trickle coming from above the black tank on the steel frame. Not sure how long this has been leaking if it is this slow and the underbelly was so full of water.

so the two questions:
is there a way water can get into the black tank without flushing?

what would be possible leak areas above the black tank that would drip down the side to the steel frame?

thanks for any suggestions,

Yes sometimes a bath sink will also dump there if too far from grey tank. No hard rule where drains lead to. Overflow can be caused by vent connection not bonded.

Thanks Vince. Both grey and black are next to each other, I will see if I can see anything.

My TT has a camp kitchen sink that dumps into the black tank. I discovered this when I inadvertently overfilled my black tank thinking that this water was draining through my opened grey valve.
