Sample interview questions: How do you ensure proper gas pressure in a system?
Sample answer:
- Utilize a Manometer:
Use a manometer to measure gas pressure at various points within the system. This instrument accurately measures the pressure and identifies areas experiencing pressure drop or inconsistencies.
- Ensure Proper Gas Line Sizing:
Choose the appropriate gas line size based on the expected gas flow rate and length. Using undersized lines can lead to pressure drop, while oversized lines may result in higher installation costs without significant benefits.
- Install Pressure Regulators:
Install pressure regulators at the system’s main gas supply and at individual appliances to maintain a consistent gas pressure. Properly adjust the regulators to ensure the desired pressure levels are achieved.
- Eliminate Gas Leaks:
Thoroughly inspect the entire gas system for leaks using a gas detector or soapy water solution. Identify and promptly repair any leaks to prevent pressure loss and potential safety hazards.
