Black tank question

[maccam1]

just this weekend,i sanitized my water lines.When i dumped the the blackwater

tank there were like plastic rubbery pieces that came out,was like an aqua blue

in color.the water was clean when it came out,except for these pieces.Does anyone have an idea what this could have been,ive never seen anything like
this in the 12 years ive had an rv.

Sounds like parts of the toilet ring seal that prevents leaks around the toilet base. BUT: typically they are black or dark gray. It may be construction residue from manufacturing ?????

If everything works as normal, I'd consider it "black tank waste", keep using the toilet, watch for more of the same and not worry too much about it.

thanks

i thought maybe it could have been a build-up of the toilet treatment,as its green in color
there are no toilet leaks,and i also flush out the tank real good after use

It's possible that it may be dried toilet water with coloring from the deodorant used to treat the contents. If left over the winter, it may have dried and look that way, but seems it might have dissolved with the flushing of the tank. Who knows. I'd just watch for "repeat samples" and keep flushing the toilet as usual.
