Gas lines connect your meter to every gas-burning appliance in the house, and from the meter forward the entire system is the homeowner's responsibility. That includes the supply to your water heater, range, dryer, and furnace. When you add a pool heater, outdoor kitchen, fire pit, or generator, each one increases the BTU demand on the system, and the existing pipe may need to be upsized. Arizona requires a licensed contractor for all residential gas line work.
We find leaks with electronic combustible-gas sensors that measure concentrations in parts per million, well below what your nose can detect from the mercaptan odorant that gives natural gas its rotten-egg smell. Once the sensor narrows the area, soap solution on the fitting confirms the exact joint. For new runs and extensions, we calculate the total BTU demand of every appliance on the system and measure the distance from the meter to select the pipe diameter that carries full volume without pressure drop. Most residential gas piping in Phoenix uses schedule-40 black iron for the main trunk and CSST, corrugated stainless steel tubing, for branch runs to individual appliances. All CSST gets bonded to the home's electrical grounding system to protect against arc damage from surges.
Every completed gas job gets a pressure test at the code-required minimum before the gas goes back on. You get a flat-rate price before work starts and a free estimate on larger jobs. Call 602-560-8989 and we will tell you honestly what the work involves.
What We Handle
Our Process
Scope the Job
For a suspected leak, we sweep the area with an electronic gas sniffer and soap-test every fitting in range. For new work, we walk the route from the meter to the appliance location, measure the run, and calculate the pipe size from the total BTU load. Either way, you see the full scope before we quote a price.
Install or Repair
We isolate the gas, replace the failed fitting or section, or run the new line from the manifold to the appliance. Pipe supports, shutoff valves, and drip legs go in at the same time. We use black iron or CSST depending on the routing and load, and all CSST gets bonded to the home's grounding system.
Pressure Test
We charge the entire system with air, hold it at the code-required pressure, and verify zero drop at every joint. Once every connection confirms zero drop, the gas goes back on. You get our lifetime workmanship warranty.
Frequently Asked Questions
Leave the house immediately without flipping light switches, striking matches, or using your phone indoors. The spark from any electrical contact can ignite gas in an enclosed space. Once you are safely outside, call 911 and then Southwest Gas's emergency line at 877-860-6020. The fire department or Southwest Gas will verify the area is safe and shut off the supply if needed. After they clear the home, call us to locate and repair the leak. The rotten-egg smell comes from mercaptan, a harmless odorant added to natural gas specifically so you can detect even small leaks by nose.
No. Arizona requires a licensed contractor to perform gas line work. Improper gas work can cause explosions, structure fires, and carbon monoxide poisoning. Beyond the safety risk, unlicensed gas work can void your homeowner's insurance and create disclosure problems when you sell.
Black iron is rigid steel pipe that threads together at each fitting. It has been the standard for residential gas piping for decades and is extremely durable in dry environments. CSST is corrugated stainless steel tubing that bends around framing and through wall cavities with fewer joints than a rigid pipe run. Most installations in Phoenix use black iron for the main trunk off the meter and CSST for the branches to individual appliances. CSST requires bonding to the home's electrical grounding system to protect against arc damage from lightning or power surges.
We use two methods together. An electronic combustible-gas detector measures gas concentrations in parts per million, picking up levels far below what the mercaptan odorant lets your nose detect. Once the sensor narrows the area, we apply soap solution to each fitting and watch for bubbles at the leak point. On new installations and repairs, we also pressure-test the entire system by charging it with air and confirming zero drop over a sustained hold. For water supply leaks, our leak detection service uses similar precision equipment on supply and drain lines.
Usually, yes. Each gas appliance adds BTU demand to the system, and the existing line from the meter may not be sized to feed another appliance without losing pressure. We calculate the total load across every appliance already connected and determine whether the existing trunk can support the addition or needs to be upsized. We run the new line, install the shutoff valve and drip leg at the appliance, and make the connection.
