The valve Closet (Fig. 51) is an excellent appliance, pro-vided economy is not considered; but, as there is a certain amountof mechanism in its construction, unless the best quality ofworkmanship is obtained, faults will very soon become apparent* toes footnote, p. 76, and also p. 87. 8ANITAET AND INSANITARY WORK AND APPLIANCES. 97 The simplest wash-down closet, of good design, is much tobe preferred to a cheap valve closet. The valve closet, apart from the fittings, consists of an earthen-ware enamelled basin, A, which is kept about two-thirds full of water by means of a valve,B, at the outlet. The waterflush is connected with therim of the basin, which isturned inwards upon itself,0, so that the dischargepasses all over the surface,in place of being distributedover one side only, as is thecase with the fan means of a pull thevalve is depressed withinbox D, which is connectedwith the basin above, andwith the soil-pipe trap be-.

The valve-box, which ought to be made of cast iron,enamelled in the inside, is connected with the trap by meansof a short conducting pipe, E. A lead overflow pipe, F, witha properly-constructed syphon-trap, G, connects the basin withthe valve-box below. Valve closets without overflows are nowfixed not infrequently; in such a case, in the event of accident,the basin overflows into the safe-tray. It is also important to ventilate the valve-box by a pipe, H,which should be carried through the wall at a convenient pointa few feet away from a window, where it should be cut short andleft open to the air. It is not necessary to continue this air-pipe upwards above the roof, the closet being self-cleansing, andthe soil-pipe being ventilated. With a
