Sample interview questions: Are you familiar with different types of pipes and fittings used in residential plumbing? If so, please explain.
Sample answer:
Types of Pipes Used in Residential Plumbing:
- Copper: Durable, corrosion-resistant, and an excellent heat conductor, making it ideal for hot water lines.
- PEX (Cross-linked Polyethylene): Flexible, easy to install, and resistant to freezing. Widely used for water supply lines.
- CPVC (Chlorinated Polyvinyl Chloride): Resistant to corrosion and high temperatures, making it suitable for hot water lines and drainage applications.
- PVC (Polyvinyl Chloride): Economical, durable, and resistant to chemicals. Used primarily for drain, waste, and vent (DWV) systems.
- ABS (Acrylonitrile Butadiene Styrene): Similar to PVC, but with higher heat resistance. Also used for DWV systems.
Types of Fittings Used in Residential Plumbing:
- Elbow: Changes the direction of a pipe by 45 or 90 degrees.
