any you guys use this tubing for heating? thought it was just lately a fad. guess not. went to press a fiiiting onto a 1 1/4 piece of tubing today in a 25 year old system, CRUSHED the tubing! not to hippy about that. a bit of searching and there it was, the infamous yellow writing, very faded. Man this POed me seriously!



oh well, the inspectors around here don't say no to such inferior ways, so who am i to argue..............

    DWV copper

    As an apprentice years ago, I went to a training class put on by our local chapter of the Copper Development Institute.  I remember the man showing us charts where it was fine to use DWV copper for heating systems.  Mostly because of the lower pressure most of them use.  I have used it many times in my systems. 

    There was an error rendering this rich post.

    DWV copper for heating

    Is very common in my area. It is not too different in thickness from type M, but still thicker than tubing used for many fin-tube rads. :-)
