Sample interview questions: How do you ensure that plumbing systems are designed to be resistant to corrosion and degradation?
Sample answer:
Corrosion Resistance
- Specify corrosion-resistant materials for pipes, fittings, and fixtures, such as copper, stainless steel, CPVC, or PEX.
- Ensure that pipes are adequately sized to prevent excessive flow velocities and erosion.
- Protect metal surfaces from galvanic corrosion by using dielectric unions or isolating flanges.
- Provide cathodic protection systems to mitigate corrosion in underground piping or areas with high moisture levels.
Degradation Resistance
- Install pipes and fittings that are resistant to degradation from chemicals, heat, and UV radiation.
- Provide adequate drainage and ventilation to prevent moisture buildup and condensation.
- Use materials that are compatible with the water supply and potential contaminants.
- Inspect for and repair leaks promptly to prevent water damage and er… Read full answer
