Gas line work belongs in a narrow category of plumbing tasks where there is no acceptable shortcut. A fitting that isn't fully threaded, a connector that was bent during installation, or a repair that skips the post-work manometer pressure test can produce a leak that's invisible and odorless until conditions for ignition are met. Masters Plumbing Service's certified gas plumbers in Fletcher, NC use combustible gas detectors at every connection point after every repair โ and every job ends with a documented manometer pressure test before gas is restored to any line we've worked on.

If a contractor quotes gas line work without mentioning manometer pressure testing or combustible gas detection at completion, that's a gap in their safety protocol that you should ask about before agreeing to any work.
No unlicensed person touches gas line work at Masters Plumbing Service. The stakes are too high for on-the-job learning.
After any gas line repair, installation, or reconnection, we pass a calibrated combustible gas detector โ sensitive to natural gas and propane at concentrations far below the lower explosive limit โ over every fitting, joint, and appliance connection we worked on. A clean detector pass at every point is required before the job is closed out.
This documentation is required by many local inspections and is the professional standard for confirming gas work is complete. Soapy water bubble testing is not an acceptable substitute for a manometer test on anything more than a simple appliance flex connector.
Gas line work โ new runs, repairs to service lines, appliance connection upgrades โ requires a permit and inspection in most NC jurisdictions. We pull the required permit, schedule the inspection, and provide you with the inspection sign-off as part of the job documentation.
Our gas plumbers handle the full range of residential and light commercial gas line work in Fletcher, NC โ from a suspect appliance connector to a full new gas run for a generator or outdoor kitchen.
If you smell gas โ the distinctive sulfur/rotten-egg odor added to natural gas for detection โ the immediate protocol is: leave the building without operating any switches, leave the door open, call your gas utility's emergency line from outside to shut off the street supply, then call us. Our certified gas plumbers arrive with combustible gas detectors to locate the exact source of the leak in service lines, appliance connectors, meter risers, or distribution piping inside the structure.
Moving a gas range, installing a new gas dryer, connecting a gas fireplace insert, or hooking up a tankless water heater โ each requires a code-compliant appliance connector (rated flexible connector or rigid pipe), correct shutoff valve accessible without moving the appliance, and a post-connection leak test and pressure test on the affected segment.
Adding a gas barbecue outlet, running gas to a new range or cooktop, extending gas to an outdoor kitchen or pool heater, or adding a gas stub for a whole-house generator โ all require a new gas line run sized correctly for the BTU demand of the connected appliances and the existing line's supply pressure.
A standalone gas system pressure test โ without any repair or installation โ is requested for several reasons: before purchasing a home with gas appliances, when an unexplained gas smell has been investigated and not found but a homeowner wants confirmation the system is sound, or at a contractor's request before final inspection.
Corrugated stainless steel tubing (CSST) is the flexible gas piping used in most newer Fletcher homes โ it's faster to install than rigid black iron and routes easily through framing. However, CSST requires specific installation requirements: proper fittings, correct bonding to the electrical grounding system, and protection at penetration points to prevent abrasion damage.
{Propane systems used in areas of Fletcher, NC without natural gas service have specific considerations compared to natural gas: different line pressures at the regulator (propane distribution pressure varies by system design), different BTU content per cubic foot, and propane's behavior of settling low (it's heavier than air, so propane accumulates at floor level rather than rising to ceilings).|We service propane supply lines from the tank to the structure, appliance connections, regulator function checks, and leak detection using detectors calibrated for propane's lower explosive limit.}
Every step exists because gas work without it is unsafe, regardless of how minor the job appears.
Our dispatcher flags gas calls for certified-only technician dispatch. No unapproved personnel work on gas lines.
On arrival, we conduct a detector survey of the full accessible gas system โ not just the suspected area. This establishes a baseline and catches any pre-existing issues beyond the immediate call scope.
You receive a flat-rate quote covering the repair or installation, permit costs, and inspection coordination before any work begins. We pull the permit, execute the work, and do not restore gas to the affected segment until the manometer test passes.
After every gas job โ repair, new run, or appliance connection โ we conduct a timed manometer pressure hold test on the affected segment and detector-test every connection point. You receive the written test result as part of your job documentation.

Faint gas smell near the furnace room โ not strong, but unmistakable. Called Masters Plumbing Service after the utility came out and said the issue was on the customer side of the meter. Their tech arrived with a detector calibrated for natural gas, walked the full accessible distribution system, and pinpointed the leak to a union fitting on the furnace supply line โ a fitting that had been vibrating loose from years of furnace cycling. Repaired the union, re-tested with detector and manometer, gas restored. Written documentation of the test result for my records.
Had three contractors look at moving a gas range โ two said they couldn't do it because of the CSST in the line. Masters Plumbing Service's tech was CSST-qualified, relocated the range connection with the correct CSST fittings, added the required bonding conductor to the grounding system, and pressure tested the modified segment. Permit closed with no issues. Very professional from start to finish.
Called Masters Plumbing Service for a propane system inspection before buying a rural property. Their tech checked the regulator function, distribution line pressure, tank connection, and all appliance flex connectors. Found one connector that was beyond its rated service life and replaced it. Written pressure test documentation and a clear condition report on the full propane system.
