Too late for most anything. It is attached to a funding bill that will be
passed and although the Governor vetoed this NAHB/BAM (Builders Association of
Minnesota) direct bill in 2012, he cannot line item veto it as far as I know.
Ten legislators (almost all of whom have already voted for the

Is CPVC involved at all? Could be issues with the CPVC if it is exposed to the
temperatures either directly or through thermal expansion.

If they aren't properly protected the bolts on the couplings will be the
Achilles heel. The safe, long-term way would be to use proper underground pipe
and fittings, in accordance with their listing.

UL tests sprinklers at a minimum operating pressure of 7psig (UL 199). The
first of many questions (that I will not ask): Are you going to propose design

Scot,
I responded to the specific question (and assumed everyone understood the 30%
increase would be applied to the roof/ceiling). However, I would not recommend
a dry system in-rack if you can avoid it. Quell, preaction, other might be
better if possible. Also, an engineered solution where
Scot,
I don't see anything that sends you back to 11.2.3.2.5 to increase the in-rack
design requirement by 30%. 11.2.3.2.5 is an area of sprinkler operation
increase, not a number of design sprinklers increase. Intuitively, yes.
Prescriptive, no.

Agreed. If they don't submit paper copies of plans, calcs, and product data it
doesn't get reviewed. You can't perform inspections without a plan, they need
a copy back with comments, and I need a copy for my files and there is no
reason for me to pay for the cost of plotting, printing and cop
