Red Seal Plumbing Complete 2026 Practice Exam

Thermal pipe movement can occur due to changes in temperature, causing it to expand or contract. Fixed brackets (option A) are not able to accommodate this movement and can result in damage to the pipe. Cementing and welding (option C) are not effective methods of accommodating thermal pipe movement as they are not able to allow for any flexibility. High tension wires (option D) are not designed to accommodate thermal pipe movement and should not be used for this purpose. Option B, which includes slip type expansion, mechanical expansion joint, offsets and loops, is the correct answer as these methods provide enough flexibility and movement to accommodate thermal pipe movement.
