When tracks are parallel, theminimum distance is 16-foot centers. A pipe line from the service water tank the full size of the stand-pipe is run connecting the two as direct as possible, so as to rendera high velocity supply; sometimes the connection is made with thecity or towns high pressure mains and charged by meter. The standpipes in general use are 6, 8, 10, and 12 inches, weigh-ing from 2500 to 5000 pounds a Drain Concrete FloorSTAND PIPE Fig. 91.
