Standpipes shall be constructed of wrought iron or steel, and shall be <br />designed to withstand a working pressure of not less than 100 pounds <br />per square inch in excess of the static head of water due to the height of <br />the standpipes. <br />B. Standpipes sha11 extend from the lowest story of the building to the top <br />most story provided that standpipes serving parts of buildings that aze <br />not of the full height of the building need extend only to the top story of <br />that part. <br />C. When more than one standpipe is required in a building they sha11 be <br />connected at the base of their risers by water supply pipes of a size <br />equal to that of the largest standpipes, to permit water from any <br />source, to apply all the standpipes. <br />D.
