I did a few inspections for a client about a year ago.
He was purchasing a home and was specifically looking for an All Electric House.
Heat Pump or Baseboard. No Natural Gas, Propane and/or Oil Heating was acceptable.
The requirement was due to the fact that He and his Family survived a Natural gas explosion in their home.
Cause of explosion was attributed to the lack of a sediment leg at the Laundry Dryer. Sediment lodged in the gas valve of the Laundry dryer allowing natural gas to leak at the completion of the Dryer Cycle. Leakage was ignited by the Water Heater.
Home exploded and was a total loss.
Client, Wife and 2 children survived.
He believed that Lightening could strike twice. He was not taking any chances.
Since then, I observe and report every instance where a Gas Sediment (Drip and/or Dirt) leg is not present.
Your mileage may vary…
