Are you trying to size a pond without having the hose stream allowance in it; Size the pump smaller, without the hose allowance?
A pond, insofar as #22 is concerned, is not a tank. However, I'm just a lowly former alternate on 22, and this hasn't been processed as an official NFPA interpretation. If you aren't feeding the UG and hydrants, or any interior hose, with what comes out of your pump, then size if for the sprinkler demand. glc -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Joe Burtell Sent: Tuesday, November 17, 2009 10:16 AM To: [email protected] Subject: Hose Allowance I could have sworn that pumps taking suction from a pond qualified for eliminating inside and outside hose allowance per NFPA 13 02’ 11.2.3.1.3 An allowance for inside and outside hose shall not be required where tanks supply sprinklers only. 11.2.3.1.4 Where pumps taking suction from a private fire service main supply sprinklers only, the pump need not be sized to accommodate inside and outside hose. Such hose allowance shall be considered in evaluating the available water supplies. Seems like it’s only private fire service mains and tanks. Can someone set me straight?
