Water cocks for wash basins are made in two general types - the compression and the Fuller types of cocks.

Their mechanism is much the same as for other similar styles adapted to the use for basins. The self-closing cocks used so largely on wash basins are compression cocks. Fig. 74 is an example of Fuller basin cock in general use. Compression cocks for the same purpose are shown on the wash basin in Fig. 90. Pantry Cocks. - In general form, pantry cocks are the same as those used for basins except that the outlet is elongated.

Sill Cocks

As a means of attaching garden hose or lawn sprinklers, sill cocks are placed on the side of the building at any place convenient for their use. Fig. 75 illustrates the method of attaching the cock to the water supply. Fig. 76 shows in cross-section its mechanical arrangement. The part A is screwed into the water supply, and B furnishes the hose attachment. The valve is operated the same as any other compression valve. In Fig. 75 the cock is shown at A with a garden hose attached. The pipe to which A is attached passes into the basement and connects to the water supply. The stop-cock B is used to shut off the water. When the stop-cock B is closed, A should be opened, so that the pipe will drain. If this is neglected during freezing weather, the pipe is apt to freeze and burst.
