A plumbing emergency in Fontana usually means one of a few things: water spraying or pooling where it should not, sewage backing up into a tub or floor drain, or a water heater that is leaking. The first step is the same in each case. Stop the water if you can, keep people and pets away from wet electrical outlets, and then call with your ZIP code to check whether a local contractor can come out.
Most Fontana homes have a main water shutoff near the front of the property, often in a box by the curb meter or on a valve where the line enters the house. It is worth finding it before you need it. Depending on your address, your water may come from Fontana Water Company or another local water agency, and your bill will show which one. For a leak on the street side of the meter, contact the water provider rather than a private plumber.
Fontana's summer heat and Santa Ana wind events put stress on irrigation lines, hose bibs and exposed piping, and newer homes in the northern hills sit on slopes where a hidden leak can travel before it shows. When you call, describe what you see, where it is, and whether the water is shut off. Ask about any diagnostic fee, the arrival window and a written scope before work starts. Our statewide emergency plumbing page explains the general process.

What counts as a plumbing emergency
Some problems can wait for a weekday appointment. Others cause damage every minute they continue. Treat these as urgent:
- Water you cannot stop: a burst pipe, a broken supply line under a sink, or a split hose bib spraying against the house
- Sewage coming up into a tub, shower or floor drain, or overflowing from a cleanout
- A leaking water heater, especially one in a garage or closet next to living space
- No water at all in the home with no utility notice
- Water near electrical outlets, panels or appliances
- A gas smell near a gas water heater or appliance
The first five minutes
- Stop the water. Every California home should have a main shut-off, usually near the water meter at the street or where the supply enters the house. For a single fixture, use the small valve behind the toilet or under the sink.
- Stay safe around electricity. Do not stand in water near outlets or appliances. Switch off power to the affected area at the panel if it is safe to reach.
- For a gas smell, leave first. Get everyone outside, do not operate switches, and call your gas utility or 911 from outside. A plumber is not the first call for a suspected gas leak.
- For sewage, stop using water anywhere in the home so more does not back up.
- Photograph the damage for your records and any insurance claim.
