Gas Shut Off at the Meter? What a Plumber Has to Do Before It Comes Back On

Why the Gas Company Padlocked Your Meter
If Atmos Energy or CoServ detects natural gas on your private house piping, their emergency crew will lock your meter with a red padlock or seal tag. Utility technicians are legally prohibited from repairing private customer piping downstream of the meter outlet swivel.
Step 1: Engaging a Texas Licensed Master Plumber
In the State of Texas, only a licensed plumber working under a Responsible Master Plumber (RMP) can legally pull municipal permits and perform repairs on fuel gas piping.
Step 2: Isolating Appliances and Precision Pressure Testing
Our technicians disconnect all gas appliances to protect internal valves, cap the manifold, attach a calibrated pressure gauge, and pressurize the system with compressed air. The system must hold pressure without dropping to prove 100% gastight integrity.
Step 3: City of Lewisville Inspection and Utility Unlock
Once the repair passes our internal test, the City of Lewisville building inspector evaluates the gauge and issues an official green approval tag, authorizing Atmos or CoServ to remove the lock and restore gas service.
Master Plumber Insight: The 3-PSI vs. 10-PSI Test Gauge & Aging Flare Valves
Restoring gas in Denton County requires passing rigorous municipal inspection standards under the International Fuel Gas Code (IFGC). Homeowners are often surprised to learn that testing is not conducted using natural gas; instead, the system is pressurized with compressed air to either 3 PSI (using a precision 1/10-pound diaphragm gauge) or 10 PSI depending on municipal amendments. The needle must hold rock-steady without moving for a minimum of 15 to 30 minutes in front of the city inspector.
In 1980s and 1990s North Texas tract homes, the root cause of pressure loss is rarely a ruptured underground steel pipe; rather, it is almost always aging appliance shut-off valves. Builder-grade brass flare valves feature internal lubricated ground-plug cores. Over decades of heat exposure behind water heaters and furnaces, this lubricant dries into rock-hard wax. When an inspector or technician turns the valve handle, the seal breaks, creating a microscopic seepage. Master plumbers immediately replace these obsolete valves with modern, non-lubricated quarter-turn CSA-approved gas ball valves with double O-ring seals, ensuring the system passes city inspection on the very first visit.
