Sample interview questions: Can you explain the process of installing and maintaining water supply lines and fixtures for laboratories or research facilities?
Sample answer:
Installation:
- Plan and Layout: Determine the location of fixtures, water sources, and access points.
- Pipe Sizing: Select pipes with appropriate diameter and material (e.g., copper, CPVC, PEX) for the required water flow and pressure.
- Installation: Run pipes and connect them to fixtures using fittings, valves, and unions. Ensure proper support and slope to prevent water stagnation and pressure loss.
- Connections: Connect fixtures to water lines using flexible connectors or rigid tubing, ensuring leak-proof seals. Install aerators on faucets for flow control and water conservation.
Maintenance:
- Regular Inspections: Regularly inspect pipes, fixtures, and fittings for leaks, corrosion, or damage.
- Valve Maintenance: Ensure valves are functioning properly by opening and closing them regularly. Lubricate or replace valves as needed.
- Fixture Maintenance: Clean and disinfect fixtures to prevent buildup of deposits, bacteria, or scale. Check and replace washers or seals as required.
