CL score today.
It has 3 posts on it..... some kind of level sensor
There is also an old, faded sticker on the side that I noticed after I got it home that looks like it says it had distilled water in it, and 'do not ingest' is on there as well. The guy I got it from said he brewed his own and used it. It had a hose & picnic tap with old brew in it, so I believe him.
What is this thing? Why does it have a 'do not ingest' sticker on it?
I think I'll just oxyclean & be on my way.
