Unit 5: Plumbing Maintenance and Repair

About this Unit

A plumber’s most common and frustrating problem is to locate and clear a stoppage in a plumbing drain waste system. A stoppage can happen anywhere in the system; in a fixture, branch line, or main line. A stoppage can be caused by hair, grease, and other foreign matter that holds back or blocks the flow of waste disposal in any part of a plumbing’s drain waste system. You, as a plumber, must be able to locate and clear any stoppage using the proper plumbing tools.
