Closing the main water valve limits the damage from almost any leak, and a gas smell means getting everyone outside before doing anything else. Once the house is safe, call the number on this page to be connected with a local plumber in San Diego.

Gas odor comes before everything
If you smell gas, do not touch light switches, appliances or a phone inside the house. Get everyone out, and once you are a safe distance away, call 911 and SDG&E at 1-800-611-7343. A plumber can work on gas piping only after the utility has made it safe.
What counts as an emergency
- Water spraying from a pipe, hose or fitting that you cannot stop at a fixture valve
- Sewage rising in a tub, shower or floor drain
- The sound of running water with every fixture off, or a warm patch on a slab floor
- A water heater leaking from the tank itself
- No water in the house while the neighbors still have it
A drip, a single slow drain or a toilet you can isolate at its stop valve can usually wait for regular hours.
Steps to take while you wait
- Find the house shutoff. The City says the owner is responsible for the plumbing from the meter onward. Many homes have a valve where the line enters the house; the meter box near the curb also has one.
- Turn off the water heater if it is leaking: the breaker for electric, the gas control set to off or pilot for gas.
- Stop using drains if sewage is backing up. Every flush adds to the overflow.
- Take photos of the water and any damage for the plumber and your insurer.
When the problem belongs to the City
Water bubbling up in the street, a broken main or a whole block without water goes to the City of San Diego Public Utilities Emergency Hotline at 619-515-3525. On the sewer side, the homeowner covers the lateral from the house to the property line. If a plumber finds the break past that line, they file a Plumber's Report with the City's Sewer Emergency Line.
Local patterns worth knowing
About half of San Diego homes were built before 1980, so older neighborhoods such as North Park and Hillcrest can still have galvanized supply pipe and cast iron drains that fail with little warning. Newer tracts are often built on slabs, where a leak stays hidden under the floor. Winter storms can overload low drains and older laterals, which is when backups tend to show up.
What to tell the plumber
Your call is routed to an independent local plumber who serves San Diego. Give the address, describe what is leaking and say whether the water is shut off. Ask how night or weekend work is priced before anyone is sent, since off-hours visits often cost more. Arrival times depend on the plumber's schedule and are not guaranteed.
