Sample interview questions: Can you describe your knowledge of different pipe materials and their uses?
Sample answer:
Copper Pipes:
– Durable, corrosion-resistant, and suitable for hot and cold water distribution.
– Used in residential and commercial plumbing for water supply lines, drainage systems, and gas lines.
– Require specialized soldering or brazing techniques for installation.
CPVC (Chlorinated Polyvinyl Chloride) Pipes:
– Economical and easy to install plastic material.
– Resistant to corrosion, particularly in hot water lines.
– Suitable for cold water distribution, water mains, and sprinkler systems.
– Connected using solvent cement, making installation less technical than copper.
PEX (Cross-linked Polyethylene) Pipes:
– Flexible and versatile tubing.
– Resistant to corrosion, freeze damage, and water hammer.
– Ideal for under-slab and radiant floor heating systems, as well as residential plumbing.
– Connected using crimp rings or expansion fittings, offering faster installation.
PVC (Polyvinyl Chloride) Pipes:
– Strong, rigid, and chemically resistant plastic material.
– Suitable for drainage, waste, and vent systems.
– Easily installed using solvent cement.
– Can handle… Read full answer
