Black water into gray water

[Kafn8td]

At the risk of making some heads spin and starting a war, I have a question. My shower drains into my black water tank - yes it was designed that way - yes it is RVIA approved etc.

The issue is, my gray water never fills up and the black fills up quickly. If it was the other way around, I would buy an equalizer (twist on waste vale)and when getting full equalize the tanks.

However, since it is the other way around, is there any reason not to do it? They are both cesspools of bacteria so I really can't think of a reason not to do it.

I would not do it just because of the size difference of the outlet pipes of the gray tank, the gray tank pipe being much smaller then the black pipe. makes no semse to be plumbed that way.

When boondocking, my grey fills a lot faster than the black. I use this to equalize the grey and black. Then when I get to a FHU site, I try to flush the grey.

It is a 2011 Cruiser Fun Finder XT276 TH. I was told it was manufactured that way to help with the water to solids ratio.

edit - I didn't consider the different size pipes. I'll have to take a better look at it this weekend.

Really thats odd.. What make/model camper is it? I would like to reseach that..

But IMO I see no issue with what you propose other then the fact that the grey water discharge pipe is smaller diameter. So if waste moves to the gray side you may be more prone to clog issues...
