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 Bensenville, 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.

These aren't marketing points โ they're the minimum requirements for safe gas line work. Every Masters Plumbing Service gas job in Bensenville, IL meets all four, on every call, without exception.
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.
A permit isn't just a bureaucratic step โ it's an independent safety check. The inspector confirms our work meets the applicable code. That second set of eyes protects you, and we welcome it.
Every job follows the same detection and pressure-testing standard regardless of scope.
Once the utility has confirmed the street supply is shut and the structure has ventilated, we locate the leak, make the repair, detector-test every connection, perform the manometer pressure test, and coordinate with the utility for gas restoration.
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.
If you have CSST in your home and it was installed before 2010, the bonding may not meet current code requirements. We can assess existing CSST installations, add required bonding conductors, and document the system for insurance or resale purposes.
{Propane systems used in areas of Bensenville, 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.}
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.
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.
The permit inspection follows, and we provide you with the signed inspection record. The job is not complete until that documentation is in your hands.

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.
I bought an older home in Bensenville that had a gas dryer stub but I'm switching to a gas range. Masters Plumbing Service traced the existing gas distribution, confirmed the supply capacity was adequate, extended the run to the kitchen with correctly sized pipe, capped the dryer stub, and provided a full manometer test on the entire modified system. Very thorough work โ documentation exactly as described upfront.
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.
