E. This is a lead-lined wood cistern, holding about 400 gallons, and supplying all the fittings in the house, with the exception of the sinks O, P, and q, and the w.c. marked J. The recommendations of the Commissioners include the construction of a louvred window in the external wall above the lead Hat over the bath-room, - this window is not shown on the corrected plan; - the alteration of the w.c. partition so that the w.c. may be effectually separated from the cistern; the division of the cistern into two parts by a lead-covered wood partition; the fixing of a galvanized-iron cittern E in one compartment; and the rearrangement of the service-pipes in such a way that the lead-lined cistern E supplies only the water-closets G, h, I, and J, and the new cistern E' supplies the hot-water system, bath, lavatories, and sinks. The overflows from the cisterns must discharge on to the lead flat over the bath-room. A new 3/4-inch main service-pipe must be laid to the cisterns, with a high-pressure screw-down gun-metal stop-cock in the scullery. The service-pipe from the new cistern must be 1 1/4 inches in diameter, and a 1 1/4-inch stop-cock must be fixed immediately under the cistern.

2 This includes £25 for forming the dormer in the roof to inclose the cisterns.
3 This includes £18. 10s. for forming the new water-closet room J, £27 for the new w.c. room k, £19, 19s. for white glased wall tiles, £12 10s. for the new w.c room M. and £80 for removing the sink k and closet N, cutting away the lead-flat over to form open area, lining the area with white glased tiles, cutting the new doorway into the kitchen, and building the walls to form new larder and scullery.
* This include* £22, 10s. for the new skylight, and shaft for light and air.
F. The zinc-lined cistern at this point is no longer required, and must be removed.
G. The w.c.-room must be detached from the cistern by a new partition plastered down to the floor on both sides. The w.c. itself is wash-out apparatus with defective joints, and must be removed; a new wash-down closet with flushing rim must be fixed.
H. This is an inferior valve-closet; the Commissioners recommend that it be removed, and a new inclosed white earthenware pedestal valve-closet be fixed in its place, as shown in Fig. 696. The floor and walls should be lined with tiles.
I. This is "a side-outlet closet with a weighted rubber-lined plunger attached to the handle and a supply-valve under the seat". As explained in the Section on "Sanitary Fittings", plunger-closets are now considered very unsatisfactory at the best; in this case the trap is cracked, and no course remains but to provide a new closet. The Commissioners recommend the use of a wash-down pedestal closet.
J. This is a wash-down pedestal closet, but is defective in having the outgo of the S-trap under the pedestal, as it is almost impossible to make a perfect joint in such a position. This closet is shown in Fig. 697. The outgo of a closet trap should invariably be above the floor, as shown in figs. 293 and 294, page 391, vol. i.

K. Instead of this wash-out closet, a wash-down pedestal-closet must be fixed, care being taken to select one without an opening for an anti-syphonage pipe, as it is difficult to plug the hole so as to be permanently satisfactory.
The old soil-pipe serving the closets G, h, I, and j was a 4-inch Beamed-lead pipe carried down inside the building, and connected with the drain at the bottom. A 2-inch ventilating pipe was continued to about 2 feet above the parapet of the roof. "When a pailful of water was thrown down closet G, the water in the trap of closet H was syphoned out below the seal." The new soil-pipe must be 3 1/2 inches in diameter, of drawn lead, weighing 10 lbs. per lineal foot, and secured to the external wall with three pairs of "stout" cast-lead tacks to each 10-feet length of pipe. The pipe must be continued about 5 feet above the parapet, and finished "with a perforated lead cap with copper-wire guard". A brass thimble must be wiped to the soil-pipe at the bottom, bo that a satisfactory connection can be made with the iron drain. A 2-inch anti-syphonage pipe must be taken, cither from the iron branch of the lowest closet J. or from the anti-syphonage arm of this closet, and carried up to about 3 feet above the closet G, where it must be connected with the soil-pipe; the trap of each closet must be ventilated into this pipe by a short branch-pipe. L. This lead-lined housemaid's sink is in an exposed position, and its waste is connected directly with the drain and is unventilated The fitting and pipes must be entirely removed.
M. This sink also must be removed, and a new sink-room formed out of part of the bath-room, a skylight being made in the lead fiat over for light and ventilation. The new sink must be of enamelled fire-clay, fitted with a 1 1/2-inch drawn-lead Strap and l 1/2-inch lead waste-pipe connected at the foot (by means of a brass thimble) with the branch-drain discharging into the disconnected gully U. The pipe must be continued as a ventilating pipe to about 2 feet above the parapet, and an anti-syphonage pipe must be taken from the trap of the sink into the ventilating pipe. The floor of the room should be covered with 7-lb. lead, copper-nailed.
N. The stone sink N must be replaced with one of glazed stoneware, fitted with a 2-inch trap and waste made to discharge into the new flushing gully b b in the front area; this gully will be flushed by means of a 30-gallon automatic Hushing tank fixed on brackets in the adjacent passage. The new partition and door at G G are intended to keep back the smells from the kitchen and scullery.
