I haven't been inside a Lowes in a while.... As I'm walking through the plumbing section I see CSST/Pro-flex.
What makes it even better they have a training manual (just like Wardflex and Gas-tite) that you can purchase for $1.98(optional of course).... And yes you can mail in the postcard so you can get your certification.
I'm sorry but this s**t doesn't belong there.

I know its just as easy to get a Gas-tite or Wardflex certification. But at least most of these supply houses are requiring one to work for a contractor or be a contractor. Also they do usually ask for the certification when purchasing CSST.
