Most gas line installs start with an appliance. Somebody wants to swap an electric range for a gas one, put a tankless water heater where the old tank was, add a standby generator before the next ice storm, or run a line out to the patio for a grill. The appliance is the easy part. Getting gas to it safely, at the right pressure and the right volume, is the job.
A gas line is not a garden hose with a fitting on each end. It has to be sized for every appliance it will ever feed, not just the new one, because a line that is too small starves the furnace the first cold morning everything runs at once. It has to be the right material for where it runs. It has to hold pressure under test before anything is lit. And in Spartanburg County it has to be permitted and inspected.
That is the whole of what we do on a gas line install: plan it around your total load, run it in the right pipe, test it, get it inspected, and light and check every appliance on the line before we leave.

You probably need a new or extended line if
- You are switching an electric range, dryer or water heater to gas
- You are adding a tankless water heater, which can draw several times what a tank did
- You want a standby generator that runs on natural gas or propane
- You are finishing a basement, adding a room or building a garage that needs heat
- You want gas to an outdoor kitchen, grill, fire pit or pool heater
- Your appliances lose flame or struggle when several run at once
What we run gas to
- Gas ranges, cooktops and wall ovens
- Gas clothes dryers
- Tank and tankless water heaters
- Gas furnaces and boilers
- Standby generators
- Quick-connects for portable generators built to run on natural gas
- Gas logs, fireplace inserts and vent-free heaters
- Outdoor grills and outdoor kitchens
- Fire pits and fire tables
- Gas lanterns
- Pool and spa heaters
- Garage and shop heaters
Sizing the line is the part that matters
Every gas appliance has a rating in BTUs per hour, printed on its data plate. A line has to deliver the total of every appliance that could run at the same time, over the full length of the run, without the pressure dropping below what the appliances need. Get that wrong and nothing leaks — the furnace, the water heater and the range just underperform, and usually on the coldest day of the year.
So the first thing we do is add up the house: what is on the line now, what is going on it, and what you are likely to add later. A tankless water heater is the usual surprise. Many draw close to 200,000 BTU an hour, several times a typical tank, and a line that fed the old tank happily often cannot feed the new unit without a larger pipe back toward the meter.
Sizing follows the tables in the fuel gas code, by pipe material, pressure and developed length. When the existing service is marginal we will say so before you buy an appliance, not after it is installed.
Black iron, CSST or poly: which pipe goes where
There are three common materials on a residential gas job in the Upstate, and each has its place.
- Black steel pipe (black iron) — the traditional choice. Threaded, rigid and durable. Right for exposed runs, mechanical rooms and short, straight drops.
- CSST (corrugated stainless steel tubing) — flexible yellow- or black-jacketed tubing that runs through walls, attics and crawlspaces with far fewer joints. It must be bonded to the electrical grounding system, which the manufacturer and the code both require because of lightning risk.
- Polyethylene (PE) — the yellow plastic pipe for underground runs outside the house, buried with a tracer wire so it can be located later. It never runs above ground or indoors; it transitions to steel where it comes up.
Natural gas or propane
In much of Spartanburg County the gas arrives from a utility main through a meter. Out past the mains — rural Chesnee, Campobello and the edges of Cherokee County — homes run on propane from a tank in the yard. We run lines for both.
The piping itself is similar, but the two fuels run at different pressures and many appliances need a conversion kit to switch from one to the other. Any appliance going onto propane has to be set up for propane, and the tank supplier sets and maintains the regulator at the tank.
New gas service, propane conversions and Piedmont financing
Gas Guys is a Piedmont Natural Gas Advantage Partner. If a Piedmont main runs near your house but you have never had gas, we help you through the new service install: Piedmont brings the service line and sets the meter, and we run the house piping, test it and get it inspected so the meter can be turned on.
The same goes for homes switching from propane to natural gas when a main reaches the road. We check whether the existing piping is sized for natural gas, convert or replace each appliance, and coordinate the timing with Piedmont and your propane supplier.
We can also offer financing through Piedmont Natural Gas for qualifying gas work. Piedmont decides what qualifies and sets the terms, so we go over the options with you before the job is scheduled.
Who owns which part of the line
Your gas utility owns the main in the street, the service line to your meter, and the meter itself. Everything downstream of the meter — every foot of pipe from the meter to every appliance — belongs to the homeowner. That is the piping we install, repair and test.
It matters for digging, too. Calling SC811 before you dig is free and it is the law, but 811 only marks the utility's lines up to the meter. A buried line we run from the meter to a detached garage, a generator or a grill is yours, and 811 will not mark it. We bury plastic gas pipe with a tracer wire so it can be found later, and we will show you where it runs.
How a gas line install runs
-
Walk the job and add up the load
We look at the meter or tank, the existing piping and every appliance on it, and work out where the new line should tie in and what size it needs to be.
-
Pull the permit
Gas piping is permitted work. We file with whichever building department covers your address, the City of Spartanburg or the county.
-
Run the line
In the right material for each stretch, with a shutoff valve and a sediment trap at the appliance, supported and protected where it passes through framing.
-
Pressure test
The new piping is capped and pressurized with air and held on a gauge. Under the fuel gas code the test is at least one and a half times the working pressure, never below 3 psi, for at least 10 minutes. Many inspectors ask for more. It has to hold with no drop.
-
Inspection
The inspector sees the test on the gauge and checks the installation before anything is concealed or connected.
-
Connect, purge, light and check
We connect the appliance, purge air from the line, light it, and check the flame and the connections for leaks. Every other appliance on the line gets relit and checked as well.

New gas piping and gas appliance installations need a permit and an inspection in South Carolina. Inside city limits the city building department issues it; in unincorporated Spartanburg County it is the county's building codes office. Cherokee County has its own office, and Gaffney permits within its own city limits.
We pull the permit and meet the inspector. A permitted, inspected line also matters later: home inspectors, insurers and buyers can ask for it, and an unpermitted gas line is the kind of finding that holds up a sale.
What drives the cost of a gas line
Every job is priced before work starts. These are the things that move the number.
- Length of the run
- Distance from the meter or the nearest suitably sized pipe to the appliance is the biggest single factor.
- Pipe size
- A high-BTU appliance like a tankless water heater or a generator may need a larger pipe, sometimes all the way back to the meter.
- Route and access
- An open crawlspace or an unfinished basement is quick. Finished walls, slab floors and tight attics take longer.
- Underground work
- Runs to a detached garage, a generator pad or an outdoor kitchen need a trench and a transition back to steel at each end.
- Meter capacity
- If the total load outgrows the meter, the utility may need to upgrade it. We tell you early, because that is on their schedule, not ours.
- Permit and inspection
- Permit fees are set by the city or county and are part of the job either way.
Who supplies gas in your town
