There are two types of gas systems: propane and natural gas. We work on both. If you’ve got a leak, you’ll smell it, due to the odorizing agents added to both of these gases. Your propane or gas utility provider (say, PG&E) might also notify you of a leak. These providers typically turn off the gas and require location, repair, and permitting by the building department before they’ll resupply gas service. The first step in this process involves isolating and pressure testing the different gas lines on the property.
You may have a gas line feeding the pool or spa heater. Some homes have gas-fed barbeques and outdoor fire pits. Other gas lines supply furnaces and fixtures in the home, including hot-water heaters, dryers, fireplaces, and ranges. Our skilled technicians valve or cap off each fixture and appliance to isolate them from the leaking line.
To safely and efficiently locate the leak, we perform a pressure test, using a non-flammable, inert gas at a higher working pressure than the gas company provides. Special tracer gas and a sensitive molecule counter pinpoints the source of leakage.
We check all the plumbing fixtures and valves with an ultrasonic listening device, and we map out the entire plumbing system using a digital radio detection pipe-line locator. This ensures the highest level of accuracy when pinpointing your leak.
