Fallbrook homes on natural gas are served by SDG&E, so for a suspected leak, leave the area immediately and, from a safe location, call 911 and SDG&E at 1-800-611-7343; some rural homes use propane instead, and they should call 911 and their propane supplier. For piping work, call the number on this page to be connected with a local plumber in Fallbrook.

Signs of a gas piping problem
- Any gas or propane smell: leave the house before making calls
- A hiss at a valve, connector or meter
- Pilot lights that will not stay lit
- Yellow, uneven flames on a range or fireplace
- Browned vegetation along the path of a buried line
Natural gas and propane in Fallbrook
SDG&E's combined gas and electric service area covers San Diego County, and it is the natural gas utility for Fallbrook homes connected to its system. SDG&E maintains the meter and its supply; the piping on the house side is the owner's. For a leak on natural gas, leave and call 911 and SDG&E at 1-800-611-7343 from a safe place.
Not every Fallbrook property is on utility gas. Some homes on the rural edges may rely on propane, though how many is not on record. If your home has a propane tank, the supplier on your delivery invoice is the one to call along with 911 if you smell gas, and the tank, regulator and first-stage piping are often the supplier's responsibility. Piping from there into the house is plumbing work.
Because Fallbrook has no city government, the County of San Diego is the permitting authority for gas piping.
Cost factors
- Distance from the meter or propane tank to the appliance
- Trenching across larger lots or sloped ground
- Whether existing piping must be upsized
- Converting an appliance between propane and natural gas
- The County permit and its inspection
What happens when you call
Plumber Oceanside refers your call to an independent plumber experienced with gas piping in Fallbrook. Say whether the home is on SDG&E or propane, what appliance or problem is involved and where the meter or tank sits. If outdoor digging is needed, the plumber or you should call 811 first so buried utility lines are marked. New and repaired piping is pressure tested before the appliances are relit, and you should get a note of what was done. If your gas has been shut off at the meter for any reason, leave it off and let SDG&E turn it back on; propane customers should have the supplier check the system before relighting.
