I am curious to know how many of you have had an AHJ require a full blown flow test be submitted with 13D calculations? 13D only requires a static pressure reading from the job site address. Reason being, it is understood that a 13D system demand (two heads flowing, 26gpm) will not over-run a municipal water system. The flow test is only required for buildings that fall under the NFPA 13 standard. The cost of a flow test can be very expensive and time consuming. Contractors must wait for the water purveyor to conduct the test.
If an AHJ requires a flow test for a 13D system, and since 13D does not require a flow test, doesn't the AHJ have to get approval from the State Fire Marshal and/or Building Standards Commission to require this expensive (and unnecessary) test? It seems to me that the only reason a plan checker would require a flow test for a 13D system is because they don't understand or recognize the reason behind a flow test. Any suggestions on how to educate a plan checker without making them look bad would be appreciated. Regards, Owen Evans -------------- next part -------------- An HTML attachment was scrubbed...
