Here's an update . . .
Still working like a champ, no leaks, no problems . . . BUT . . .
Last night, it started turning the liquid BLACK. Ink black. I blew it out a bit, re-primed, and vaped some more . . . fine for a bit, but it blacked up quickly.
So I've switched out for a new one, cleaned out the old one and I'm letting it soak for a bit.
Is this gonna need more frequent cleaning? Or did I do a dumb somehow?
That's the first I've heard of ANY atty doing this. Are you using black tanks? Is it possible the tank itself is melting or the dye is turning the liquid black? toss a teaspoon of baking soda in your atty, with a little vinegar, then put your thump on the large opening. This will force the foam out through the top, and it's a guaranteed way to clean up anything dirty in that atty. Rinse it out, let it dry off, and try again.
