I've been replacing my burner tubes for over 20 years on my Weber grill. It looks a little outdated but still going strong! Over time the burner tube start to wear out and I change them about every two years. Weber makes outstanding grills that can last a lifetime with a little TLC! I keep my grill covered and out of the weather. I would hate to part with it but when the time comes, I will definitely only get a Weber grill!
