Gas service in Mentone
Mentone is an unincorporated community in San Bernardino County, east of Redlands on the south bank of the Santa Ana River and on the SR-38 route into the San Bernardino Mountains. Its north-south streets are named for gemstones. SoCalGas lists Mentone among the communities it serves. Water and sewer can come from the City of Redlands for some parcels, but Redlands does not supply gas, and Mentone has no city government of its own.
That affects permits. Because Mentone is unincorporated, San Bernardino County is expected to be the permit authority for gas and plumbing work, though our fact sheet did not confirm the specific county office. Check with San Bernardino County before work starts; a plumber who works in the area will usually know the process. Some outlying homes in foothill areas use propane rather than utility gas, and a propane leak means leaving and calling 911 and your propane supplier.
Choosing the right fix
| Problem | Typical fix | Notes |
|---|---|---|
| Small leak at a fitting | Remake the joint and retest | Check nearby joints too |
| Valve that will not close | Replace the valve | Needs gas off at the meter |
| Old appliance connector | Replace with a new coated connector | Quick job while the appliance is out |
| New appliance or outdoor line | New branch sized for load and distance | County permit, test, inspection |
Signs not to ignore
- A smell of gas inside or near the meter (leave first)
- Hissing at a shutoff or connector
- Lazy yellow flames or soot at burners
- Pilot lights that go out on cold nights
- Dead vegetation over a buried line
Seasonal notes
Mentone sits at the edge of the foothills, and winter nights can be colder than on the valley floor, which keeps furnaces and water heaters busy. Late summer and fall are good times to fix slow leaks and replace tired valves. For outdoor projects, call 811 before digging so SoCalGas and other utilities can mark their lines. In earthquake country, keep the water heater strapped and the main shutoff easy to reach. When you call, mention whether the home is on utility gas or propane and roughly how far the work area is from the meter.
