NFPA13D - Residential Fire Pumps
Residential fire pumps generally fall under the National Fire Protection Association's 13D codes. NFPA-13D covers the construction and installation of fire sprinkler systems for one & two-family dwellings and mobile homes.
Sprinkler demand in a residential system is normally calculated by the water flow required to run two sprinkler heads simultaneously for 10 minutes. A common flow for sprinkler heads is 15 gallons per minute. This means that a normal home with a normal system would require a 30GPM supply in order to meet code. Since standard utility company meters can't keep up a homeowner/builder has the choice of having a larger meter installed (these cost a lot to begin with and come with a monthly charge whether their higher capacity is used or not) or buying a water storage tank to meet the 10 minute supply demand. Water tanks are cheap and cost nothing once installed.
Water flow is only one of the factors in sprinkler demand though. The other is pressure. In order for the sprinkler head to cover enough area to be effective it must have the water delivered with enough force(PSI). Many homes will have enough pressure. However, pressure without flow won't put out a fire. This leads back to the choice of either having a larger meter installed, along with its monthly charge, or buying a 13D system and tank. 13D systems are often much cheaper than the larger meters and cost nothing once installed.
That's where we come in. Our LSF Compact Residential Fire Pump systems are backed by years of expertise and are fully tested before they leave our facility. We also include important safety features not offered on any other system in our price range because lives depend on it. With 10 models capable of anywhere from 25 to 170 GPM flow, system pressures of up to 95 PSI, and all small enough to disappear into a corner, TALCO has your residential fire protection needs covered.
