Anyone in Highland who smells gas should leave the house, then call 911 and SoCalGas at 1-800-427-2200 from outside. For leaks after the meter, new lines and pressure testing, call the number on this page to be connected with a local plumber in Highland.

Gas piping in Highland
Highland grew from citrus groves and the railroads at the southern base of the San Bernardino Mountains, and it is now divided into Highland, East Highland and West Highland. SoCalGas serves the city. The housing mix matters for gas work: about 44 percent of homes were built before 1980, and the median build year is 1983, with the 1980s and 1990s as the busiest decades. Homes around the Palm Avenue historic district and the older parts of town are the likeliest to have iron gas pipe that has been tapped and extended over the years. Newer East Highland tracts are more often a question of adding capacity.
The City of Highland Building & Safety Division, at 27215 Base Line, requires permits for plumbing systems and for water heaters. Expect gas piping changes to go through permit, pressure test and inspection.
Repair or replace?
| What you have | Repair makes sense when | Replacement makes sense when |
|---|---|---|
| Leaking fitting or union | The rest of the run is sound | Several joints on the same run are weeping |
| Stuck shutoff valve | Rarely; valves are usually swapped | It will not turn or leaks at the stem |
| Old appliance connector | Never worth repairing | Any time it is old, kinked or uncoated brass |
| Corroded section of pipe | Damage is limited to one spot | Rust is widespread or outdoors in soil |
Signs to take seriously
- Gas smell anywhere in the house or yard (leave and call from outside)
- Hissing from a valve, union or connector
- Yellow, noisy or lifting burner flames
- Soot around a water heater or furnace
- Pilots that will not stay lit
Seasonal notes
Highland sits closer to the mountains than much of the valley, and cold winter nights keep furnaces and water heaters busy. Fall is a good time to fix slow leaks and stiff valves before that demand peaks. Spring and fall also suit outdoor projects; call 811 before trenching so SoCalGas can mark its line. In earthquake country, check that the water heater is strapped and the gas connector has some slack. When you call, say whether the home is in East Highland, West Highland or the older core, since that hints at what kind of piping the plumber will find.
