For a Corona plumbing emergency, stop the water at your main shutoff first, and if you smell gas, get outside and call 911 and SoCalGas at 1-800-427-2200. Leaks at the street or meter go to the City of Corona Utilities Department. For anything on your side of the meter, call the number on this page to be connected with a local plumber in Corona.

Signs it should not wait until morning
- Water running out of a ceiling, wall or sink cabinet that keeps going after you close the fixture valve
- A warm or damp spot on a slab floor, or the sound of water moving when every tap is off
- Sewage or gray water rising in a shower, tub or floor drain
- A water heater pooling water around its base
- A broken supply or irrigation pipe you cannot isolate
- No water at any fixture while the neighbors still have service
A dripping faucet or a slow bathroom sink is a nuisance, not an emergency. The items above can ruin flooring and drywall in a few hours.
How water and sewer work in Corona
Corona runs its own utility. The City of Corona Utilities Department supplies the water and also provides sewer service to its water customers, with wastewater treated at City water reclamation facilities. If the trouble looks like a break in the street or at the meter, the Utilities Department line is (951) 736-2234; after hours, press option 1 for the stand-by crew. Leaks inside the house or along your own piping are work for a plumber.
The City says pressure regulators are the customer's responsibility to replace. A regulator that fails can let household pressure climb high enough to burst a supply hose or trip a relief valve, so a plumber may test it during an urgent visit. Corona's water averages 146 mg/L hardness (about 8.5 grains per gallon), which the City classes as hard, and scale inside an older tank is one reason heaters give out without warning. The utility's inventory found no lead service lines and no galvanized lines needing replacement, and it asks owners to notify it before altering or replacing a service line.
What moves the price
- Timing. Night, weekend and holiday calls normally cost more than a weekday booking.
- Access. A leak under a slab or behind tile takes longer to reach than one in a garage or attic.
- Scope. Replacing one fitting is quick; a new water heater or a sewer repair is a larger job.
- Permits. The City of Corona Building Division handles plumbing permits and inspections through eTRAKiT, and a replacement heater or new line can add that step.
What happens when you call
The call connects you with an independent plumber who works in Corona. Have the address ready, say whether the main is closed, and describe what you can see. Ask how after-hours pricing works before anyone is dispatched. Arrival depends on the hour and the plumber's workload, so no arrival time is promised.
