When a supply pipe bursts in a Corona house, closing the main valve comes first, then a repair that removes the split section and restores pressure. Corona Utilities handles trouble on its side of the meter. Call the number on this page to be connected with a local plumber in Corona.

Clues that a pipe has failed
- Water running across the garage floor or out from under the water heater
- A bubble or brown ring forming on a ceiling
- Pressure dropping at every faucet at once
- The sound of rushing water inside a wall
- Soaked carpet or baseboards along an interior wall
- A soggy patch in the yard along the path of the service line
Local conditions in Corona
The City of Corona Utilities Department runs the water system. If water is surfacing at the meter or in the street, call the Utilities Department at (951) 736-2234 and press option 1 after hours for the standby crew. Customer Care is (951) 736-2321. The City has also completed its service line inventory and reports no lead lines and no galvanized lines that need replacing, so a break on the yard line is rarely about lead.
The City says pressure regulators are the customer's responsibility to replace. That matters for bursts, because a regulator that has failed open lets higher street pressure into the house, where it pushes on every joint and hose. If pipes or connectors keep failing, have the regulator checked during the repair. Corona also asks owners to let the utility know before they alter or replace their service line.
Corona's water is hard, averaging 146 mg/L (8.5 grains per gallon) in the City's latest Consumer Confidence Report. Scale doesn't split pipe on its own, but it can freeze an old shutoff valve in place, so check yours now.
What changes the cost
- Where the break is, whether open framing, a finished wall, under tile or in the slab
- The pipe type and how many fittings are involved
- Whether a regulator or water heater connector also needs replacing
- Digging, if the failure is in the buried line from the meter
- Permits through the City of Corona Building Division, which takes applications and inspection requests online through eTRAKiT
- After-hours timing
What happens after you call
The call is routed to an independent plumber who serves Corona. Tell them where the water is showing up, whether the main is closed, and how old the house is if you know. The plumber locates the rupture, replaces the damaged piece with new pipe, brings the water back slowly and checks the joints nearby. If the house pressure seems high, ask for a gauge reading before they leave.
