Here if you add one head at all you calculate. If you relocate any head more than five feet total including break over and drop you calculate. If the existing facility has a pump. You need a current a certified pump by a manufacturer rep or sealed by a PE And you need to take it the street tie in with a current flow test performed by a AHJ certified tester and witnessed by the city.
We figure calculating every job so no matter what size job it's going to be 2500 out of the gate. But it's the standard so everyone is equal. That is as long as you read the city requirements for permitting.

I'm not talking about changing densities or even going from standard to extended coverage sprinklers. I just mean your average run of the mill add/relo project. We have run into a fire marshal that feels it is required on all projects now. The one that they are currently fighting is just a tenant change in a strip mall. Building has been around for nearly 30 years. Water supply in area is very stable. Would you normally figure a full calculation on this type of project? -- Travis Mack, SET MFP Design, LLC 2508 E Lodgepole Drive Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107 email:[email protected] http://www.mfpdesign.com https://www.facebook.com/pages/MFP-Design-LLC/92218417692 Send large files to us via: https://www.hightail.com/u/MFPDesign LinkedIn: https://www.linkedin.com/in/travismack _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
