Yea, Right, In central PA you lucky to get a flow test within a mile of the proposed project and less than a year old. And the engineer of record is mechanical engineer who might recognize a sprinkler if you threw it at him. But that's another discussion. Tomorrow off 1st in 13 days.

Do not shot me for this - but SFPE defines water supply adjustments/evaluations are the responsibility of the engineer of record for the project (item d below). See the white paper on the role of the engineer/technician for more details. Maybe we should allow or make the engineers do their job! Water-based suppression systems: a) Selection of type of system and components b) classification of the hazard and commodities to be protected c) establish the density/flow and design area size d) determine and confirm the available water supply e) preliminary system layout and hydraulic calculations to verify adequacy of proposed water supply arrangements f) analysis to identify concerns regarding systems structural support (as appropriate) g) analysis to identify any concerns with water quality that would affect the proposed systems (as appropriate).

It may well be a requirement, but back to my rhetorical question: who's actually doing it? SL -----Original Message----- From: Sprinklerforum [mailto:[email protected]] On Behalf Of Mark A.

Oh, and BTW, taking those seasonal/local/whatever fluctuations into account IS noted in NFPA 13 - so one could argue correctly that it is a requirement of "code" (assuming your code references NFPA 13).

How many people, when requesting or performing a flow test or flow model, specify that the values be measured at peak seasonal and peak day demands? How much fluctuation does a given water system or zone experience in a day/week/month/year? How many of us review those fluctuations and factor them into a flow test once it's taken? ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
