As can be imagined by the title. I am very confident in my ability to build a washer capable of taking on a carboy or Pepsi keg. I'm just not sure if it will work in a Sanke keg. Likely it will require the spear to be removed. I might be able to accomplish building a set up where you could leave it in but visually verifying that the contents are cleaned will be impossible. I am a Quality Control inspector by trade and therefore the lack of ability to inspect the post cleaning condition doesn't sit well. My main question is, would anyone have any interest in me posting my process with a very thorough listing of my parts used (names of parts, where I bought them and how much $) ? I have seen a few build and they just kinda say "3/4 PVC and 1/4" hose barb". That's lame to me, I have found a few parts that make the build pretty neat, I'm just waiting on everything I ordered to be delivered. So... Any interest?
