Not every plumber is certified for gas work in MO. Our gas plumbers hold active state certifications for natural gas and propane installations, carry CSST-qualified training for flexible corrugated stainless steel tubing systems, and document every job with a written pressure test result before we close out.

These aren't marketing points โ they're the minimum requirements for safe gas line work. Every Masters Plumbing Service gas job in Falcon, MO 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.
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.
A manometer measures gas line pressure precisely over a timed hold period. After any repair or new installation, we isolate the segment, pressurize to test pressure, connect the manometer, and hold for the required duration. Zero pressure drop confirms a leak-free installation. We document the test result โ pressure, hold time, and pass/fail โ and provide you with a copy.
Gas line work โ new runs, repairs to service lines, appliance connection upgrades โ requires a permit and inspection in most MO jurisdictions. We pull the required permit, schedule the inspection, and provide you with the inspection sign-off as part of the job documentation.
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.
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.
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 Falcon 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 Falcon, MO 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.
Active gas smell: stay out of the building, call your utility to shut street supply, then call us. Non-emergency gas work (new runs, appliance connections, pressure testing): call to schedule โ we confirm certification documentation and permit requirements for your specific job scope before arrival.
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.
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.

Needed a new gas line run to an outdoor kitchen setup. Masters Plumbing Service sized the line correctly for the combined BTU load of the burners and the side burner, ran 3/4-inch black iron through the crawl space and up through the exterior wall, installed a shutoff at the outlet, pressure tested the new segment, and handled the permit and inspection scheduling. Inspection passed first time.
I bought an older home in Falcon 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.
