I wanted to post this because with all my searching all I ever found was people using black pipe, copper, or those ugly yellow flex appliance lines for their rigs. (no offense intended to those who have used these methods) I wanted something more like what you would find on a commercial BBQ. I searched and asked and searched some more... and short of the RV camping supply store and a few spots on the web I couldn't find what I was looking for. And, even those options I was stuck with weird lengths and the wrong fittings on the end.
So I finally came to the idea to go to my local gas supply store. I went initially to ask about purchasing a large 40lb tank and see what they charged for gas. What I left with was custom made lines for my brew rig! They cut custom length lines for me and fit them with fittings that I chose. (they had any size and I could ever need!) I was so happy and took back all the black pipe I had bought as this solution solved every issue I had. (flare to pipe converters, being able to adjust the height of burners without replumbing, turning corners, etc) not only that but it was CHEAP!!! I got out of there for a fraction of what I would have paid to fully plumb my rig. so check it out if you are looking for an inexpensive alternative!
In addition I found a neat way to get around buying a new, large tank to feed my BG14's. after some research I went back to the propane shop and got a unit made up that cost me 8.50... it is a splitter of sorts that basically hooks to 2 or 3 20lb tanks and uses them as 1 big tank. Those 20lbers are more readily available to fill and exchange than the big guys and I already have 5 of them. So, it is certainly work taking a look at.
Anyway, a couple of things I thought might interest us DIY Home brewers.
