Gas Line Repair in Union, SC
Union is split: 34% of households are on mains gas and 5% on bottled or tank propane. Those are two different arrangements with two different answers about who owns the pipe.
Read this first
Union splits between mains and tank gas, at 34% on utility gas and 5% on bottled. Which one a property has decides where responsibility changes hands: a meter outlet marks the boundary on mains gas, while a tank puts the whole installation on the owner.
Source: US Census Bureau, American Community Survey table B25040; the service line boundary is 49 CFR § 192.3.
If you smell gas right now
Leave the building on foot. Do not use a phone or a light switch inside. Call 911 and your gas utility from somewhere else, and do not call us — we are a referral service, not an emergency line. The full list, in order.
How Union is supplied
Where both are common, so is the assumption that they work the same way. They do not: on mains, part of the system is somebody else’s responsibility; on propane, none of it is.
| Households in Union | Share |
|---|---|
| Utility (mains) gas | 34% |
| Bottled or tank propane | 5% |
| Electricity | 57% |
| Fuel oil and kerosene | 1% |
| Wood and everything else | 2% |

What B25040 measures is the heating fuel, not the connection. It is the closest published proxy for whether there is a buried service line here, and it is a proxy. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across South Carolina as a whole, 31% of households are on mains gas and 3% on tank propane. Union sits about level with the state on mains and 2 points above it on propane. Averages are where this kind of difference disappears. The figures on this page are the town’s own for that reason.
Before anyone digs on the property
Before any digging — a fence post as much as a foundation — call 8-1-1. It is a nationwide toll-free number, it costs nothing, and PHMSA puts the chance of avoiding an incident afterwards at 99 percent.

What to ask whoever quotes it
Ask them to describe the fault before they price it. "The line needs replacing" is not a diagnosis, and on a buried run the difference between one damaged point and a line at the end of its life is most of the cost.

Checking a plumber in South Carolina
South Carolina licenses are issued by the South Carolina Residential Builders Commission, Department of Labor, Licensing and Regulation, which publishes a public search you can use before work begins. South Carolina requires a residential plumber license for work over $500, according to the Commission.
Gas work is separately permitted and separately licensed in most jurisdictions, so ask specifically about gas rather than plumbing in general.
For repair work, not for a suspected leak.If you can smell gas, leave and call 911 or your utility from outside; this is the wrong number for that. For everything else — a line, a meter, an appliance connection — we will route you to a contractor covering your area, free of charge to you. We serve Union for plumbing that has nothing to do with gas.
