FAQ
Common questions
+What exam does this prepare me for?
The Ontario Plumber (306A) Certificate of Qualification exam. Practice follows the exam's trade topics, while code-specific study is focused on the Ontario Building Code, not other provinces' plumbing rules.
+Are these real exam questions?
No. Every question is original, written around public 306A trade objectives and Ontario Building Code plumbing topics. These are not actual or recalled exam questions.
+Which code book should I study?
Use the current Ontario Building Code: Division B, Part 7 for plumbing and Part 8 for on-site sewage systems. Check applicable amendments and confirm requirements in your own copy. This site is not a substitute for the official code.
+How does the AI tutor work?
Ask in plain language — code questions, venting, offsets, pressure math — and get a step-by-step explanation. You can also send any practice question straight to the tutor.
+How long do I get access?
Six months from purchase, with every feature included.
+Is this affiliated with Skilled Trades Ontario?
No. PlumbingExam.ca is an independent study tool. Book and confirm your exam with Skilled Trades Ontario.
