As plumbing is now constructed, even the cheaper grades of work include a large amount of nickel work, in which there is a great variety of material to select from.
Bi-transit wastes are extensively used on baths and lavatories of the better grades. This device allows the waste to flow out by the lifting of a plunger instead of the ordinary plug. It adds a certain finish to the fixture, but also adds a complication which provides additional surface, which may become foul and produce odor. In general the simpler plumbing devices are the more satisfactory. Nickel-plated supply pipes should be of iron-pipe size, rather than of tubing, as the former can be screwed into the concealed iron piping, while the tubing must be connected into it by soldered joints, which are not so substantial.
Combination cocks for baths and lavatories are very satisfactory. Both hot and cold water are led into the same cock in the combination devices, and by properly regulating the supply of each, the water may very easily be tempered as desired.
Fuller work is almost entirely used on high grade work, notwithstanding that the quick closing of this work is often accompanied by vibrations and disagreeable rumbling of the pipes, which is entirely absent in the slower closing compression work.
On much of the cheaper work cast-iron, nickel-plated lavatory brackets are used. These are not satisfactory, as in time the iron will rust through the nickel plating, and the bracket will present a very shabby appearance.
