All lines of cold water supply pipes, except the branches under the fixtures, are lap-welded extra-heavy (not the standard) galvanized-iron pipes, warranted to be tested by hydraulic pressure of 500 pounds per square inch. Concealed branch supply pipes at all fixtures are heavy drawn AAA lead pipes, required to weigh as follows:

In all public and private toilet-rooms, except em-ployees', all exposed supply pipes at fixtures (not the rising supply mains) are nickel plated brass pipes, with nickel plated brass hangers, hold-fasts, escutcheons, etc. Numbered polished-brass tags are attached to all shut-off valves in the building, except at the shut-off valves directly at the fixtures, the use of which is obvious, and corresponding printed lists are prepared, giving number, location, and description of every shut-off valve in the building so as to avoid any possibility of mistake or confusion in their operation.

There are in this building, exclusive of the fire valves, etc., the following apparatus and fixtures - viz: One drip tank, about 63 water-closets, 15 slopsinks, about 52 urinals, 20 washbasins in toilet-rooms, about 166 office washstands, one bathtub, one kitchen gas range, one kitchen and two pot sinks, two engineer's sinks and one pump sink, two grease traps, one kitchen boiler, heated by Vulcan gas-burning attachment, one hot-water tank, two roof tanks, two intermediate tanks, one suction tank, two distributing drums, three pumps, one water meter; total about 343 fixtures. The location of these fixtures is: 15 in pipe cellar, 16 in basement, eight in first floor, 17 in second floor, 19 in third floor, 19 in fourth floor, 19 in fifth floor, eight in sixth floor, four in seventh floor, 24 in mezzanine floor, between seventh and eighth, 20 in eighth floor, 19 in ninth floor, 10 in tenth floor, 19 in eleventh floor, 19 in twelfth floor, 19 in thir teenth floor, 18 in fourteenth floor, 17 in fifteenth floor 17 in sixteenth floor, 27 in seventeenth floor and on roof.

The plumbing in general is " exposed work " - i. e., all fixtures are arranged in an open manner, and all pipes and plumbing-work kept exposed to view. The finish at fixtures is of nickel-plated brass in all general and private toilet-rooms and of all office washstands, and of lead and galvanized wrought-iron silver bronzed for all employees' fixtures. All toilet-rooms are fitted up complete with marble partitions and have no woodwork, except the doors to closets, which are short flap doors, paneled, trimmed, with brass hardware, the latch operated from the inside, and with rubber striking tips and single-action butts, bolted to marble jambs with brass spherical-headed bolts. Marble platforms 1 inches thick are placed under all water closets, slopsinks, urinals, and washbasins, and under kitchen and wash sinks, and bathtub.

The washstands and all urinals and water-closets are supplied with cold water only. All slopsinks, kitchen sinks, pantry sinks, engineer's sink, and bathtubs have both hot and cold water supplies. All washstands are supplied with cold water only, but in the engineer's bathroom there is both hot and cold water. Where basins have cold water only a raised marble button is provided in place of the hot-water faucet, so that in case hot water shall be wanted in the future a hot-water faucet can be fitted up. The standard size for bowls is 15x19 inches for all 22x33 inch square slabs, and 14x17 inches for all corner slabs and for the smaller square slabs. Over each urinal or set of urinals is placed a patent automatic flushing cistern, copper-lined, and encased in marble of design to correspond to the water-closet cisterns. The capacity of each tank is such that each urinal receives a one-gallon flush. With each of the 19 fire valves (one in each story) there is connected 75 feet of 2 - inch three-ply heavy unlined linen fire hose, guaranteed to stand a pressure of 300 pounds per square inch.

All main drain, soil, waste and leader lines are of heavy asphalted wrought-iron pipes of standard make. The pipes and their fittings are of a uniform thickness of not less than one-fourth inch. All pipes and fittings were tested by hydrostatic pressure and by hammer test at the pipe mills, and a written guarantee was filed that such test had been applied. All vent pipes and vent fittings are galvanized. The weight of heavy wrought-iron pipes is as follows:

6-inch pipe, 18/ pounds per foot

All joints in iron pipe are screw joints, made absolutely tight by a mixture of red and white lead.

The 1-inch hot-water riser has several swivel joints to provide for the expansion and contraction due to temperature changes. Underground pipes are laid in a well-graded trench, and after inspection were bedded and covered with cement, leaving exposed only the handholes for access, which are surrounded with brick manholes and furnished with cast-iron frames and covers. All connections between lead and iron pipes are made by means of extra-heavy brass screw ferrules, or nipples, screwed into the iron fittings, and connected with the lead pipes by wiped joints, and all ferrule joints were included in the test of the soil pipes. All iron pipe fittings for branches are Y or half-Y branches, except on upright lines, where curved or sanitary T Y's are used, and on vent pipes, where common T branches are used. No quarter-bends nor ordinary offset fittings are used on soil or waste pipe stacks. One-sixth, one-eighth, and one-seventh bends, or the new pattern {45 degrees) offset fittings are used. All outlets not used for connections are properly closed with brass trap screws and kept accessible. All connections between vertical stacks and horizontal pipes are made with Y branches and eighth bends. All junctions of branches with the main house sewer are by Y branches. All vertical lines of soil and waste pipes are provided with Y branches or T Y's for outlets in each story In cases where such outlets are not used they are securely closed with brass trap screws. On horizontal lines T Y branches are not used, but they are used on upright lines.
