Signs your gas line needs attention
If you suspect a gas line issue, look for these common warning signs. Addressing them promptly can prevent serious safety risks:
Rotten egg smell: For safety, natural gas is odorized to smell like sulfur or rotten eggs in the event of a leak.
Higher gas bills: Unexplained spikes may indicate a leak or inefficiency in your gas line.
Hissing sounds: Hissing or whistling near pipes or appliances often indicates a gas leak.
Malfunctioning appliances: Gas-powered appliances not working efficiently or making unusual noises may point to reduced gas flow or leaks.
Physical symptoms: Feeling dizzy, nauseous, or fatigued at home could be due to exposure to natural gas, requiring immediate evacuation and professional help.
Dead or dying vegetation: Unexplained dead or dying plants in your yard, especially near gas lines, can indicate a leak.
If you suspect a gas leak, evacuate the premises immediately and call the gas company or 911 from a safe location away from the house. Do not go back inside or open the garage door from outside.
