I'll always wonder how someone actually installed a 6 main in a Wal-Mart

bottom chord of joists that was just that wavy Z-purlin material. Didn't the
installers have a clue? Didn't the AHJ see it on the walk-thru? Owner's rep?
I believe a spkr drop penetration can drop thru a rated ceiling without
concern about being overly cautious on the patch- we're allowed the
escutcheon to cover the hole, and I don't know that there was a dimensional
restriction on the size of the penetration. Maybe use pie-pan (metallic)
Using the same logic, would that put a crimp on using CPVC, special
application heads, EC heads, interstitial heads, ESFR (obstructions can be
missed or added later), Attic heads, and anything else that's not

An adjustment for lowest tank gradient is not only prudent, sound
engineering, it may stop the N word (negligence) from coming up at trial.
We ask the water purveyor for the tank level during the flow test and the
lowest level they reasonably anticipate where the tank low point is, and we
adjust
How about the system that dropped 45 PSI at our demand flow-
from when the FM flow test used as basis of calc and ordering 2500 GPM
diesel pump in 12~18 month time frame was performed till we did the
acceptance test? Pump worked great, but what happened to the city?
Eight flow tests later, and
We've had an instance where the water co bumped a PRV up a bit for us to
make a system work. Unusual, but we found a human.

Naturally, those of us who get it will point out to a PE when he crosses

Nothing wrong with telling the Owner, just not on the Inspection Report.
Separate letter.
FE firm got what they deserved, I suppose- reinforced by trying to change
out just the bottoms of the dry pendents. That'll change the cost of the

Good point you make about
Matt, you could quote both ways, and note that the electrically supervised

you may have another dilemma if you're under the I-Codes, depending on when
system was installed and what was the prevailing building code. It's
