3. My local natural gas (or propane) company turned off my gas after detecting a leak. Can you authorize reconnection without an inspection?: No. Once a gas service has been disconnected we are required to witness a gas test prior to authorizing reconnection. It is unlawful for anyone (including the utility) to reconnect the gas service without first receiving authorization from the Humboldt County Building and Safety Department.

4. How do I perform a gas test on my "site built" house or manufactured home?

For a "site built" home, the code requires a gauge which measures in "Pounds per Square Inch" (PSI). The test consists of the gas line pressurized to a minimum of 20 PSI for 20 minutes. The test will then be conducted in the presence of a Building Inspector, and upon successful completion of the test, the Building Inspector will authorize service with your local natural gas or propane utility. (

Rules regulating manufactured housing are specified by the Manufactured Housing Division. Under Nevada law manufactured homes shall have their gas systems tested with a manometer gauge. (This is an instrument capable of measuring in water column (WC)"). The test shall be conducted with the entire system pressurized between 10 inches of water column (10 inches WC) and 14 inches of water column (14 inches WC) for a minimum time period of 10 minutes. When this test is successfully completed, the Building Inspector will authorize utility connection. (See Nevada Administrative Code 489.440.)
