Gas Line Repair in Spartanburg, SC

Black steel pipe lasts a long time indoors and dry. The trouble spots are where it is not dry. A crawlspace that floods every spring, a pipe resting on a wet sill or a masonry pier, or a line strapped against an exterior wall where rainwater runs down will rust from the outside in. The pipe looks solid until a wire brush goes through it.

Threaded joints are the other common failure. Unions and fittings near appliances get bumped, torqued when a water heater is swapped, or were made up years ago with dried-out compound. They tend to leak slowly, a smell that comes and goes rather than a hiss, which is why many of them go unnoticed for months.

Then there is age. Older homes around Spartanburg can carry a mix of original steel, later additions in different materials, and connectors that predate current standards. A repair is a good moment to look at the rest of the line, not just the joint that leaked.

The flexible tube between the shutoff valve and the appliance is a connector, not piping, and it has rules of its own. It has to be listed for gas, sized for the appliance, kept to the length the manufacturer allows, and it cannot run through a wall, floor, ceiling or the appliance housing. A connector that gets pushed back and forth every time the dryer moves eventually fatigues and cracks.

Some older connectors are uncoated brass, and the consumer safety agencies have warned for decades that their flare fittings can separate. If you find a dull brass-colored tube behind an old range or dryer, replace it rather than reuse it. A new coated stainless connector is a small part and a big improvement.

Leaking unions get taken apart, cleaned and remade, or replaced outright if the seat is damaged. We do not crank on a leaking union until it stops bubbling; overtightened fittings crack and fail later.

Where a gas line comes out of the ground and turns up the house wall, the pipe sits in damp soil, mulch and splashback from every storm. That few inches at grade is where steel corrodes fastest. If the riser has heavy scale or pitting at the soil line, it gets replaced, usually with a factory riser that has a protective coating and a built-in transition from buried plastic.

Buried steel lines from decades ago are a bigger question. Bare or poorly wrapped steel in the ground corrodes along its whole length, and a single leak is often a sign of more to come. In many cases the right repair is to abandon the old line and run new polyethylene pipe with a tracer wire, which does not rust and can be located later.

If a line was cut or crushed while digging, the damaged section and any stressed fittings nearby are replaced, and the whole line is tested. A pipe that was yanked can crack a fitting several feet away from where the shovel hit.

Your gas utility owns the main, the service line to the meter, and the meter and regulator assembly. If the leak is on that equipment, the utility repairs it, and you should call them. In most of Spartanburg County that is Piedmont Natural Gas, and Greer CPW serves the Duncan, Lyman and Wellford area.

Piedmont's South Carolina service regulations put the customer's piping and equipment, from the meter assembly onward, on the customer to keep in good and safe repair. That covers every foot of pipe to every appliance, above ground and buried. That is the work a licensed contractor does.

SC811 is free and required before you dig, but it only marks utility-owned lines up to the meter. Your buried line to a shop or a grill is not marked. If you are planning a fence, a patio or a garden bed near where gas might run, ask us first and we can help work out where it is.
