Roland,
But it is not an arm-over if it is a horizontal pipe (not a return bend,
drop or sprig) fed from a cross main...it is, by definition, a branch line.
You must restrain it if it is required to have a hanger.

Subject: Re: Restraint of Branch Lines
so would you restrain one and not the other? I still think the
restraint does not apply to an arm-over regardless if it is tied
directly to a cross main or a branch line. Short is short (or should
I say vertically challenged?).
Having said that, I have given up on trying to say what any large
group will ultimately decide (that being the technical committee)
until it's done. I will look to see if there is a proposal that we
can attach a comment that will clarify this issue come the Sept ROC
meeting.
