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 Roxana, IL 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.
We also detector-test any existing connections near the work area that weren't disturbed, to confirm no pre-existing issues in the adjacent line.
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 IL 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 Roxana, IL 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.
Flexible corrugated stainless steel tubing (CSST) connections require proper bonding in most IL jurisdictions to prevent damage from nearby lightning events โ a code requirement many contractors overlook. Our gas techs are CSST-bonding trained.
We calculate BTU load for the intended appliances, size the new line in black iron or CSST per the installation context, install at the required depth for buried runs, and perform pressure testing on the new segment before any appliances are connected.
We pressure-test the full distribution system or individual branches per client request, provide a written test result, and report any pressure drop with our best assessment of where the loss is occurring.
Corrugated stainless steel tubing (CSST) is the flexible gas piping used in most newer Roxana 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 Roxana, IL 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.}
Gas line work follows a defined protocol โ no steps skipped, no "close enough." Here's exactly how a Masters Plumbing Service gas call runs from your first contact to a documented, pressure-tested result.
Our dispatcher flags gas calls for certified-only technician dispatch. No unapproved personnel work on gas lines.
For new installation work, we assess the existing supply line pressure, measure the BTU demand of the new appliances, and calculate the required pipe diameter for the new run before quoting.
For leak repairs, the gas remains off on the affected line until the repair is complete, the detector passes every joint, and the manometer test confirms a leak-free system.
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.
Commercial kitchen remodel required moving two gas lines and adding a new connection for a salamander broiler. Masters Plumbing Service sized the header and branch lines for the total connected BTU load, pulled the required commercial permit, executed the work, and provided a full system pressure test documentation for the health department inspection file. Clean work, inspected and passed first visit.

Our gas plumbers hold active IL certifications for natural gas and propane, and we carry combustible gas detectors and digital manometers on every gas-call vehicle.

Active gas emergency: leave the building, call your utility, then call +1-855-718-1500.
