Gas Leak Detection
A suspected gas leak requires immediate attention. Natural gas can escape from damaged pipes, loose fittings, leaking valves, appliance connectors, underground utility lines, or improperly completed gas-system modifications. Because many gas lines are concealed behind walls, above ceilings, beneath floors, or underground, the source of the problem may not be visible.
RDZ Plumbing and Drains provides professional gas leak detection for homes, businesses, restaurants, rental properties, and multi-unit buildings throughout San Diego. Our plumbers inspect accessible gas piping, evaluate affected appliances and connections, and use appropriate testing methods to locate the source of the leak.
Once the affected section has been identified and the property has been declared safe for repair work, we explain what caused the problem and recommend the appropriate gas-line repair or replacement.

Important Safety Information
If you smell natural gas, hear hissing near a gas line, or believe a gas pipe has been damaged, leave the building or affected area immediately. Do not operate lights, electrical switches, appliances, vehicles, phones, flames, or anything that could create a spark while you are still near the suspected leak.
Do not return to the building until the appropriate emergency or utility personnel have declared the area safe.
Professional plumbing inspection and repair should begin only after the immediate hazard has been addressed and the gas supply has been shut off or isolated when necessary.
Professional Detection for Hidden Gas Leaks
Gas leaks are not always located directly beside the area where the odor is strongest. Gas can move through wall cavities, utility spaces, crawl areas, cabinets, ceilings, and other connected openings before it becomes noticeable.
A suspected leak may come from one small appliance connector, but it can also involve a longer section of concealed or underground piping. Replacing the nearest visible fitting without testing the surrounding system may leave the actual problem unresolved.
Professional gas leak detection helps isolate the affected pipe, fitting, valve, or connection before repair work begins. This reduces unnecessary access work and provides a clearer basis for deciding whether a localized repair or larger pipe replacement is required.
Signs of a Possible Gas Leak
The most recognizable warning sign is an unusual sulfur-like or rotten-egg odor added to natural gas. Other possible indicators include hissing or whistling near piping, damaged fittings, corrosion around valves, dead or discolored vegetation above a buried gas line, or unusual movement of dust and debris near an underground leak. PHMSA identifies unusual odors and hissing or roaring sounds as possible pipeline-leak indicators.
A gas leak may also be suspected when an appliance repeatedly loses fuel supply, several gas appliances stop operating correctly, gas usage increases without a clear explanation, or the utility company shuts off service after identifying a pressure problem.
