Question: A plumber is connecting a 25 mm (1 inch) copper supply line to a potable water manifold in a confined space. The use of an open flame is strictly prohibited due to fire safety concerns. Which joining method provides a reliable, code-compliant connection in this scenario?
Answer options:
- Soldering with lead-free solder ✅ ProPress system with a hydraulic crimper
- Compression fittings with brass ferrules
- Threaded fittings with PTFE tape
Correct answer: ProPress system with a hydraulic crimper
Explanation: The ProPress system (a type of press-connect) is ideal for this scenario as it creates a secure, leak-proof joint without an open flame, addressing the fire safety concerns. Soldering directly violates the no-flame rule, compression fittings are less reliable for permanent connections in this size, and threaded fittings are not typically used for joining copper tubing.
