Question: A plumber is contracted to replace an existing hot water tank with a new tank of the same capacity in a single-family dwelling. The work involves disconnecting the old tank, installing the new tank, and reconnecting to existing water and venting systems. Which of the following statements regarding permits and inspections is most likely true in this scenario according to typical Canadian provincial plumbing codes?

Answer options:

• A permit is not required as it is a like-for-like replacement and does not alter the plumbing system significantly.
• A permit is always required for any hot water tank replacement, but an inspection may not be necessary if the installer is certified. ✅ A permit and a final inspection are typically required for hot water tank replacement to ensure compliance with safety and code standards.
• Only an electrical permit is required if it's an electric hot water tank; no plumbing permit is needed.

Correct answer: A permit and a final inspection are typically required for hot water tank replacement to ensure compliance with safety and code standards.

Explanation: In most Canadian provinces and municipalities, replacing a hot water tank, even like-for-like, typically requires a plumbing permit and subsequent inspection. This ensures that the installation adheres to current code standards, especially regarding venting, temperature and pressure relief valve discharge, and water connections, which are critical for safety. While some minor repairs might be exempt, replacing a major appliance like a hot water tank almost always requires oversight.
