Thetford Aquamagic V Leaking

Good day all! I'm new here. I have been reading alot of stuff here, but never made an account. I particularly like reading about peoples DIY mods and such. For the most part, any questions I have had, I could find a thread here somewhere where the topic was beaten until it was a dead horse.

And thank you for that!!

However, I have a question that I can't find the answer to. We have a travel trailer. This is our 3rd season with it. We've been pretty happy with it so far. However, we have developed a 'leak' in the toilet.

Here is a picture of the unit that is leaking. The water is coming out where the black plastic that is where the hose connects fresh water joins the white plastic of the unit (it's circled in red on the picture... sorry about the poor quality of the picture, btw...)


There's no cracks or anything like that, so I was thinking that I should be able to just put some glue in there. I was originally thinking about ABS cement/solvent, but this doesn't feel like ABS to me.

So, my question... what type of plastic is this? What type of glue can I use? Is it ABS? or PVC? Or something else? Should I just get some epoxy and glob it in there?

Thanks in advance for any help!!!
