Ok I am not going to try and pass the buck; I have been running straight distilled water in my PC-50 for about 6 months. I planned to redo the loop so I didnt bother with water wetter initially. Anyway I went to change the system around today, and noticed this:
There was also some white residue and discoloration on the CPU itself. Not good, I thought.
So I pulled the block completely apart and checked the barbs:
I didnt use teflon tape on the barbs; that is not supposed to be there! And what is up with the discoloration and oxidation of one of the barbs? Not good at all.... So inside there was (as expected) a mess:
It was a bit slimy; not sure if it is bacterial growth as well or what. I also haven't decided yet whether the block is corroded through at the alum/copper interface (causing the buildup on the base outside the block) or if a bit of water just leaked down there. I will see if I can get the block's insides cleaned and then pressure test it. Nothing was wrong with any of the other parts of the loop as far as I could tell.
Just thought you'd like to see the pictures and laugh at me. I put some water wetter into my new loop btw
