Gas Line Repair & Installation in Phoenix & Scottsdale, priced before we start.
The outdoor kitchen quote arrives, 11 pages long, with a built-in grill, a side burner, a fire feature and a pizza oven that needed its own delivery truck. Somewhere on page nine sits a single line: “gas by others.” That line is where we come in, and it is usually the part of the project that decides whether the rest of it works.
Natural gas reaches most houses at very low pressure, roughly a quarter of a PSI once it leaves the meter. At that pressure, the size of the pipe does the work. Each appliance is rated in BTUs per hour, printed on its label, and the pipe has to deliver the total of everything that might run at once, over the full length of the run. Undersize it and nothing explodes. The burners just go lazy and yellow, and the new appliance never performs like the showroom model.
That is why a tankless water heater so often needs a new gas line. A typical tank heater burns around 40,000 BTUs an hour; a whole-house tankless unit can ask for close to 200,000. The half-inch line that fed the old tank can’t supply that, and a pool heater on the same run makes it worse. Anyone running the numbers on tankless should put this line item in the math.
One rule outranks everything else on this page. Natural gas has no smell of its own; the utility adds the rotten-egg odor so you will notice it. If you notice it indoors, leave. Don’t flip light switches, unplug anything, open the garage door with the remote or go hunting for the source. Once you are outside and well away from the house, call the gas utility’s emergency line or 911. The utility makes the house safe. The repair and the retest come after.
Every new line we install is permitted, pressure tested on a gauge that has to hold, and inspected before gas flows. Existing piping gets checked joint by joint with an electronic detector. You see the gauge, you get the photographs, and the price is agreed before any pipe is cut.
What a gas problem smells, sounds and looks like
A rotten-egg smell, even a faint one
Near the meter, the range or the water heater, it means something. Strong, or anywhere indoors: leave first, then call the gas utility or 911 from outside.
Hissing near a line or an appliance
A small leak at a fitting can be audible in a quiet garage. Do not go looking for it with a lighter, a flashlight you switch on in the room, or your nose. Leave and call.
Dead plants or bubbles over a buried run
Gas escaping underground displaces the air in the soil and kills what grows above it. After a monsoon rain or a sprinkler cycle, a leaking line can bubble up through a puddle. Watch the runs to pool heaters and outdoor kitchens.
Why is the gas bill up in June?
Summer is when most Phoenix houses use the least gas: the furnace is off and the water heater starts with warm water. A bill that holds steady or climbs when it should drop deserves a pressure test.
Burners with lazy yellow flames
A healthy flame is mostly blue. Tall yellow flames and soot point to poor combustion, sometimes from a starved supply line, sometimes from the appliance itself. Either way, keep a working carbon monoxide alarm near the bedrooms.
An old brass connector behind the range
Uncoated brass flex connectors from decades past are known to crack at the flare fittings. If yours is dull gold with no plastic coating, replace it. It is a small job with a large payoff.
How a gas line gets done properly
- 01
Load first
We total the BTU rating of every appliance on the system, present and planned, and measure the length of each run. Pipe size comes from those two numbers, not from whatever was left on the truck.
- 02
Permit, then pipe
Inside the house that usually means black iron or CSST, the yellow-jacketed flexible line, which must be bonded to the electrical ground. Buried runs to a pool heater or a grill go in polyethylene with a tracer wire, so the next person with a shovel can find them.
- 03
The gauge has to hold
New piping is pressurized with air and watched on a gauge. If the needle moves, there is a leak, and we find it before the inspector does. The test gets photographed for your records.
- 04
Every joint, every appliance
With gas restored, each connection is checked with an electronic detector and each appliance is lit and its flame inspected. A water heater with a pilot that won’t stay lit gets looked at before we leave.
What it costs
Quoted flat, before we start
What moves the price: how far the gas has to travel, whether the run goes through an attic, a wall or a trench, whether the existing line from the meter can carry the new load or has to be upsized, and the permit. Larger projects, such as a full outdoor kitchen or a tankless conversion, qualify for financing.
Financing is available on larger jobsGas is the one system in the house where “close enough” is not a measurement. The gauge holds, or it doesn’t.
