The American Surety Company uses the fourth, fifth, sixth, and seventh stories for its own purposes, the first, second, and third stories are devoted to banks and special commercial purposes, and all have washbowls, closets etc., arranged to conform to their special requirements. Above the seventh floor the building is intended to be rented in suites of private offices, and the arrangement of rooms and plumbing fixtures throughout is similar to that shown in Fig.

13, which is a plan of the eighth floor and typical of all floors above it except the eleventh, shown in Fig.

14, and the thirteenth, which is very much like it. Figure 15 shows the arrangement and connection for two interior washbasins supplied from one set of risers that are carried in the partition.

Figure 16 similarly shows two basins, the risers to-which are run along an interior column.

Figure 17 shows the arrangement and connections when only a single basin is served from an interior column line.

Figure 18 is where two basins are set adjacent to an exterior column, and Fig. 19 is where a single basin is set against an interior wall.

Floor Plans And Details At Fixtures 223

Figures 17, 18, and 19 show the expansion loop introduced in the hot-water riser to compensate for temperature elongations, and in all these Figures the hot and cold water faucets above the basins and waste valve are omitted to avoid confusion.

In all lavatories and at all isolated basins, all exposed pipes at fixtures (not the rising supply mains) are nickel-plated brass pipes. There are separate shut-offs for the supplies to each and every fixture, including shut-effs at each urinal and each water-closet flushing cistern. All water-closets have glazed earthenware traps molded in one piece with the water-closet bowl. All connections between floor flanges of water-closets and iron pipe are made with short lengths of D lead pipe to avoid rigid connection. Besides iron sinks and some fixtures in the subbasement, the list of bowls, etc. throughout the building is as follows:
