They did a lot more than just test at peak supply, they crossed the line of coincidence into fraud and deception.
I'd be looking at the pipe diameter tables, etc. in their calcs, apparently there's not much this guy wouldn't do to gain a nickel at the expense of life safety and everything else we, as an industry, stand for. glc -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Travis Mack, SET Sent: Friday, February 27, 2009 10:03 AM To: [email protected] Subject: RE: system review I believe it states the flow test shall be done at peak demand and seasonally adjusted for lower fire flows, or something of that sort. It sounds like they went and got the test done when the conditions were perfect. I hope that a fire only occurs during the time you specified. :-( -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Garth W. Warren Sent: Friday, February 27, 2009 7:31 AM To: [email protected] Subject: system review Question for the lettered members and others with experience and/or an opinion - I recently looked at the riser of a new system installed in my home town. The system requirement according to the hyd. calc. nameplate states 377.9...@75psi. The system gauges read 60psi static. When I contacted the water superintendent he stated the installing contractor took the hydrant flow information used to design the system. He also stated that he head been asked to have the standpipe full and to have both Town pumps turned on before the hydrant was flowed. He continuede that it is standard procedure to have a water department employee respond to the water plant for every fire department discharge to turn on the pumps. He stated the standpipe is filled once weekly prior to weekends so that water employees do not have to work weekends then the standpipe is drawn down, filled during the week..... It appears the "best case scenario" was used in taking the hydrant flow making the system suffient only when the standpipe is filled and both pumps are in operation. I do not see anything in 13 which tells anyone how to determine the acceptability of hydrant flow data, however if the gauge states there is 15 pounds less static pressure than what is required residually for the system to operate - then there is a problem. Is there any requirement for engineers or others to apply acceptability standards to hydrant flow data or can the results purposely be slanted? It seems the system will operate properly Thursday 10am through Friday at 4pm....... The local AHJ states he accepted the opinion and acceptance of the engineer hired to review and accept the system. I do not know if this firm or individual has any training in fire protection systems, or if he has provided any such credentials to the AJH. This is in the State of NY. opinions? thoughts? code references? standard references? thanks in advance, Garth retired fitter _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) __________ NOD32 3894 (20090227) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
