To determine if your existing gas lines need to be replaced or repaired:
Check for leaks: Smell for a sulfur-like odor and listen for hissing sounds.
Inspect for corrosion: Look for rust or damage on visible lines.
Monitor performance: Note if gas appliances are not working efficiently.
Assess age: Older lines may need replacement due to wear.
Get a professional inspection: A certified technician can accurately diagnose issues and recommend repairs or replacement.
