While dumping the black tank, a piece of material came out that I cannot identify. It is about 1/16 thick an very uniform in thickness. It breaks apart easily like shale, it looks like it was formed in layers. One large piece is rounded like it was in the corner of the tank.
Is there a coating inside the tank, or could this be build up? Any thoughts? I have electric toilets.
