Standing water between Toilet and Black Tank

[Family of 6]

We have a 2190Ex. There looks to be a ledge or something between the toilet and black tank. We get about an inch or two of standing water in that spot and I can’t seem to get it out. I tried raising the side of the camper to flush it out and I tried rocking the camper. It gets pretty smelly. Any ideas?

Welcome to the forum

When you say ledge, can you see it without removing the toilet? Is the water coming from the toilet when you flush?

When I look down the toilet with the valve open, I can see standing water. If I take my snake, I can feel the pipe to the blank tank at the edge of this ledge . However, if you go straight down, there seems to be a flat spot that collects dirty water and TP. I am just curious if this is a manufacturing defect or if this is normal. Seems to me like that flat spot shouldn’t be there.

So the water is pooling IN the black tank? If so it sounds like your tank isn’t flat across the bottom. There are tanks that have a “shelf” where the toilet dumps and it’s normal for that style of tank. Use LOTS of water to rinse it off, and as long as it’s inside the tank, your going to smell it unless you use some type of treatment.

Thanks! I am actually going to be replacing the toilet since it is a Dometic 300 series. There is some kind of warranty issue where black water gets stuck in the toilet cavity. When I do, I am going to see if there is anything that can be done to slope that area a bit towards the pipe to the black tank instead of pooling.
