About this Unit

Plumbing fixtures are receptacles for personal sanitation that discharge waste disposal into the main sanitary waste system of a building. Fixtures are manufactured in vitreous china, enameled cast iron, stainless steel, fiberglass, or plastic. These materials are durable, corrosion-resistant and nonabsorbent. All fixtures come from the manufacturer with rough-in instruction on how to install the item. Fixtures such as lavatories, sinks, water closets, and urinals are installed after the finished building walls and floors are completed. Once installed, all fixtures are tested for mechanical operation and leaks.
