DIY reculating keggerator line cleaner
This is a simple project, the idea is to connect the beer lines to a small pump and themselves in such a fashion to recirculate beer line cleaner. After a short while you have clean beer lines. It’s also cheap to assemble, I’ve got less than $10 invested in this, but if you had to buy a pump, I would recommend a utility pump. It would add a bit more to the cost, but a utility pump is useful to have.
