Not to mention the other chemicals that come from distillation. It's fine for hot water, but alcohol vapor will cause pex to leech into your product.


Under no circumstance use pex where alcohol vapors can contact. I may just send this kit back and build one I've never used them and I don't plan to. Safe as in possibly springing a leak and causing a fire, as well as safe as in not containing substances that could be harmful if ingested. They felt very cheap and since they came from China i did not trust that they were safe to be used. The lines that came for hooking the boiler to the thumper, and the thumper to the condenser were very thin "stainless" flex lines. All i know is mine was the size of a small soup pot maybe a quart and a half. I've also read that others use one a quarter of the size of your boiler. I'm no expert, but from what I've read you want your thumper to be around half the size of your boiler. Use the search feature on the forum and you'll find plans. You're much better off reading about designs and building your own. I didn't bother with trying to fix my "thumper" because it is WAY to small to be effective. I bought one from Amazon as well with the same problem. I went to a local hardware store and the only thing they had to fit it was PEX, brass and galvanized pipe. The nipple inside the thumper lid is 1/2” outside diameter. Which defeats the purpose of the thumper so I need to know what materials I can use to make one. I put it together and found that when the vapors leave the pot and enter into the thumper the down pipe(from the lid to the bottom) inside the thumper is not a part of the still. Hello, I have a new still that was purchased from Amazon.
