Sample interview questions: How do you ensure proper water pressure and flow in plumbing systems?
Sample answer:
Ensuring Proper Water Pressure and Flow
- Inspect and clean fixtures: Clogged aerators, showerheads, and faucets can restrict water flow. Periodic cleaning and maintenance will remove debris and improve pressure.
- Check and adjust pressure reducing valve: A malfunctioning pressure reducing valve can cause low or excessive water pressure. Adjust or replace the valve to maintain optimal pressure (typically 45-60 psi).
- Install an expansion tank: Thermal expansion can cause pressure spikes in closed plumbing systems. An expansion tank absorbs excess pressure, preventing damage to fixtures and pipes.
- Ensure adequate pipe sizing: Undersized pipes can restrict flow and reduce pressure. Use the appropriate size pipes for the expected water demand to ensure proper flow.
- Check for leaks: Water leaks, even small ones, can significantly reduce water pressure. Inspect all fixtures, joints, and pipes for leaks and… Read full answer
