Do this now: plumbing emergency in San Diego

1. Smell gas? Leave first, then call 911 or the gas utility from outside. The Kansas Corporation Commission says not to use light switches, phones or garage door openers on the way out, and not to look for the leak.
2. Stay out of standing water near outlets, cords or appliances. The Red Cross warns not to touch electrical equipment if it is wet or if you are standing in water.
3. Shut off the main water valve to stop a leak or burst pipe, and leave a faucet open.
4. If the sewer break is beyond your property line, the plumber reports it to the City's Sewer Emergency Line, 619-515-3525.
5. Water pressure suddenly high? The City says the most common cause is a faulty pressure regulator on your property, which is yours to maintain.
6. Photograph the damage before you clean up, then call your insurer. FEMA says to take photos before cleanup begins. Do not sign your claim over to a contractor.
7. Call the plumber line and ask for the service call fee before anyone is sent.

Is it an emergency? When to call a San Diego plumber tonight

An emergency plumber costs $170 an hour on average nationally in Angi's 2026 data (no San Diego figure is published), so call after hours only when water is running and you cannot stop it, sewage is backing up, or you smell gas.

• Call now: burst pipes, sewage backups, gas leaks, major leaks, a main water line break or a water heater flooding the area, all on HomeGuide's emergency list.
• Call now: the only toilet in the house is fully clogged, or pipes are frozen and at risk of bursting (HomeGuide).
• Can wait for business hours: a dripping faucet, a running toilet or one slow drain.
• For a concealed pipe leak, the City's leak adjustment must be requested within 120 days of the first high bill, with the repair invoice.
• Generic questions about rates and fees are on the national emergency plumber page.

Who pays for a broken sewer lateral in San Diego

The homeowner does, at least up to the property line. The City of San Diego says owners are responsible for maintaining the lateral from the property all the way to the connection with the sewer main, and that the homeowner must repair the part between the house and the property line. If a plumber finds a break or collapse beyond the property line, the plumber should call the City's Sewer Emergency Line at 619-515-3525.

Ask for a camera inspection so the plumber can show where the break is. HomeAdvisor's national figures put a sewer camera inspection at $270 to $1,740 and sewer line cleaning at $190 to $570. See sewer line repair for repair methods.

High water pressure and San Diego's regulator rule

You must have a pressure regulator if the water pressure in your area is more than 80 psi, the City says, and the regulator is the owner's responsibility. The City says the most common cause of a sudden rise in pressure is a faulty regulator on your property. To have the pressure in your area checked, call 619-515-3525.

San Diego's hard water: about 16 grains per gallon

San Diego drinking water averages about 16 grains per gallon, or 276 ppm, and ranges from 16 to 18 grains per gallon, the City's Public Utilities Department says. Give that number to anyone quoting a softener or a tankless heater.

Permits and earthquake straps for San Diego water heaters

Single-family homes and duplexes can use the City's Simple No-Plan Combination Permit for electrical, mechanical and plumbing work, and homeowners, property owners and licensed contractors can obtain simple permits. California Health and Safety Code 19211 requires every new and replacement water heater to be braced, anchored or strapped against earthquakes. Prices are in water heater repair.

San Diego leak adjustments and water use surveys

The City may adjust a bill for a non-irrigation concealed pipe leak if the request arrives within 120 days of the first high bill, with the repair invoice; irrigation, pool and fixture leaks are excluded. Call 619-515-3500. The City also offers water use surveys for owners and tenants it bills (619-980-9754), though it says they are not a specialized leak detection service. For that, see leak detection.

California's minor work exemption rose to $1,000 on January 1, 2025, CSLB says, so anyone taking a job of $1,000 or more, or any job that needs a permit, must be licensed. Check the license online or at (800) 321-CSLB (2752).
