Back to an old question but a little different. Tank with sufficient capacity to supply duration for both a yard hydrant and the sprinkler system. Pump sufficient to supply required psi to the sprinks and meet the AHJ's requirement at the hydrant. Question: When calculating the sprinks do I need to add the 250 gpm hose allowance on that demand curve? This seems to be a 'safety cushion" for a water supply controlled by an outside party such as a municipality. This is not the case here wherein the quantity of water and delivery pressures are completely controlled: a closed versus open system if you will.
