| I was told it had to be black pipe up the side and inside.
That is just what one propane supplier required
We put one regulator on the tank and ran copper to the second regulator on the building, then ran black pipe from there.

We had to flair the copper fittings instead of compression fittings.
In my mind the compression fittings would have been just as good. | |
