According to Carson Dunlop’s comprehensive guide “Everything You Need to Know about Gas Piping,” natural gas stands out as an economical and efficient choice for heating systems. However, with its benefits come significant safety concerns, particularly for homeowners. As a home inspector, it’s crucial to be vigilant about identifying potential deficiencies that could jeopardize the safety of occupants relying on natural gas.
Inspecting gas piping involves understanding the layout and components of the system. The piping within a house, known as the gas supply line or building line, connects to branch lines that lead to individual appliances. These branch lines terminate in drop lines or risers, which are vertical pipes descending from overhead branch lines to the appliances.
Critical components in gas piping inspections include sediment traps, dirt pockets, or drip legs located at appliance connection points. These features, consisting of a nipple and cap, serve to capture any water or foreign material present in the gas before it enters the appliance, thereby safeguarding its functionality and safety.
It’s essential to note the division of responsibility regarding gas piping. While the piping downstream of the gas meter falls under the homeowner’s jurisdiction, the piping upstream and the meter itself are typically the responsibility of the gas company.
Regarding materials used in gas piping, options vary based on regional regulations and utility preferences. Common materials include black steel, galvanized steel, copper, brass, and CSST (Corrugated Stainless Steel Tubing). However, it’s vital to adhere to local guidelines regarding acceptable materials to ensure compliance and safety.
