IA Plumber case studies
IA Plumber · Put your knowledge to work in context.
An Iowa plumber license is a state-issued credential that authorizes a person to install, alter, and repair plumbing systems under Iowa's plumbing law and the plumbing code the state has adopted. It is administered at the state level through the Iowa Plumbing and Mechanical Systems Board, and it comes in tiers: journeyman, master, and plumbing contractor. Candidates typically start with the journeyman exam after accumulating field experience, then progress to master and contractor credentials, each with its own examination and eligibility rules. The exam is multiple choice and tests code knowledge as much as trade judgment. Topics on this exam: General Regulations, Administration and Definitions, Plumbing Math and Pipe Sizing Calculations, Drainage Systems and Drainage Piping, Vents and Venting Systems, Traps, Interceptors and Special Wastes, Water Supply and Water Distribution, Plumbing Fixtures and Fixture Fittings, Water Heaters and Temperature Control, Fuel Gas Piping and Gas Appliances, and Backflow Prevention and Cross-Connection Control. The IA Plumber case studies are 5 cases and about 1,922 words.
