The exam covers four major blocks: plumbing theory and code (hydraulics, venting, water-service sizing, drainage), pipe-fitting and joining methods (soldering, brazing, threading, fusion welding, press-fit, push-fit), fixtures and appliances (water heaters, faucets, backflow preventers, gas appliances), and safety and codes (WHMIS, gas codes, building codes).
