Introduction
Overview	This is an overview of Waste Systems, EN5112
Proponent	This subcourse is issued by the-- U.S. Army Institute for Professional Development (AIPD) U.S. Army Training Support Center Newport News, Virginia  23628-0001
Purpose	This subcourse will enable you to prepare, connect, and install pipes in a waste system of a building. Made of different materials, these pipes must sometimes be cut and the ends prepared to take fittings. The pipe-to-pipe or pipe-to-fitting connections are made with lead, collars, threads, solvent cement, and solder, depending on the pipe material used. As the pipe system is installed, it must be supported with hangers and holders. Sometimes, the building structure must be cut into when installing the waste and vent pipeline runs for lavatories, sinks, water closets, and urinals. Once a system of rough-in waste pipelines with venting is installed, it is tested for leaks.
Target Audience	Any eligible person may enroll in the subcourse.
Requirements	To receive credit for course or subcourse completion, you must-- Have an Army Correspondence Course Program (ACCP) USER-ID and PASSWORD. Be formally enrolled in this course/subcourse through the ACCP. Earn a passing score on the subcourse examination.
