WATER SYSTEMS FOR FIRE PROTECTION

Issue 17 and Volume 43.

WATER SYSTEMS FOR FIRE PROTECTION “Is it safe to depend on a gravity or direct pumping system having a static pressure of too lb. to the sq. in., with pipes, mains and laterals of sufficient size so that the drop in pressure will not exceed five or ten per cent, during the progress of an ordinary fire? Is it necessary to hold steam fire engines in reserve in cities and towns possessing such a system as here described ?” The two systems herein described differ materially one from the other, and, taken from a fire-protection standpoint, the gravity system is an entirely different proposition from that of direct pumping, and, in order to answer the above questions intelligently, each system must be treated separately and some comparisons made. Gravity pressure is constant and is limited to the pressure given by the height of water in the reservoir or standpipe. Direct…
