Plumbing is an important feature in the house, but one which the layman finds difficult to criticise intelligently. Note can be taken, however, of the character of the fixtures, whether they are porcelain or iron enamel, or of still cheaper material. The general appearance indicates the general character of the plumbing job, and the various plumbing connections show plainly the character of the plumber's workmanship. A well-nickeled, well-set connection is easily noted. A cheaply made and poorly mounted connection indicates cheap material and careless workmanship, and it is fair to assume that where the exposed plumbing work is poor, that the work which is hidden is of the same character.

Note should be taken that the washtubs and sinks are large enough for reasonable services, and that all fixture connections are of nickeled brass.

The investor planning to purchase a large and important building may well employ the services of an experienced plumber or sanitary engineer, to examine the technical features of the plumbing work, so as to advise him as to their adequacy, suitability, etc.
