As a partnership between the federal government and provinces and territories responsible for apprenticeship training and trade certification in their jurisdictions, the Red Seal Program sets common standards to assess the skills of tradespeople across Canada. Those tradespersons who have successfully passed the Red Seal examination will receive a Red Seal endorsement on their provincial/territorial trade certificate. Plumbers install, repair and maintain plumbing fixtures and systems such as water, hydronic, drain, waste and vent (DWV), low pressure steam, residential fire, chemical, and irrigation. They also install specialized systems such as medical gas, process piping, compressed air, water conditioners, fuel piping, sewage and water treatment, and storage and flow equipment. The Plumber Red Seal Occupational Standard is developed by Canadian trade representatives. It collects information about the trade as it is practiced across Canada. We create these self-practice test questions module referencing the concepts and principles currently valid in the exam. Each question comes with an answer and a short explanation which aids you in seeking further study information. For purpose of exam readiness drilling, this product includes questions that have varying numbers of choices. Some have 2 while some have 5 or 6. We want to make sure these questions are tough enough to really test your readiness and draw your focus to the weak areas. Think of these as challenges presented to you so to assess your comprehension of the subject matters. The goal is to reinforce learning, to validate successful transference of knowledge and to identify areas of weakness that require remediation. 160+ practice questions are included in this book.
