Downstairs toilet, is only normally used for #1's. The curiosity is that what I am guessing is a slightly oily film, dark in appearance appears just on the water line around the bowl a few times. Rather than around the water line, this last time, the bottom of the bowl was covered in a dark film. Not a problem, it washes away with just a flick of the toilet brush, but where might it be coming from? Why only the downstairs toilet? Why now, it has never happened before, just this past year?
I'm CKD4, might that be something to do with it?
Both cistern entire mechanisms were replaced by me a few years ago and work fine, no problems, no leaks. Not in the plumbing section, because I'm not sure it is a plumbing issue.
