oil lines & co2 cartridges

dana p._2

is it in the mass code book about NOTusing co2 cartridges to blow out oil lines

Charlie from wmass

Not sure if it says not to specifically I will need to check

BUT I was always told to not do it as popping a line, joint or seal could be a big cleanup nightmare. If the line is that clogged that your push pull won't clear it maybe you need to fix the cause and start with new pipe?
