When a water heater problem is an emergency
A leaking tank, a gas smell or no hot water for a household is an emergency, and our line is open 24/7. While you wait, shut off the cold water supply to the heater and turn off its power or gas control.
Same-day and after-hours visits are offered when a crew is free. If you smell gas, leave the house first and call SoCalGas at 1-800-427-2200 from a safe place.
- Close the cold water shutoff valve above the heater to stop the supply to the tank.
- Set the gas control to off, or switch off the breaker for an electric heater, if it is safe to reach.
- If you smell gas, leave the building, do not touch light switches or make any flame, and call 911 if there is danger.
- Move items away from the heater and mop up standing water to prevent slips.
Common problems and likely causes
| Symptom | Common cause | Usual repair |
|---|---|---|
| No hot water, electric heater | Failed heating element or tripped thermostat | Replace the element or reset and test the thermostat. |
| No hot water, gas heater | Pilot out, thermocouple worn or gas valve fault | Relight, replace the thermocouple or gas valve. |
| Water only lukewarm | One of two elements failed, sediment in the tank | Replace the element and flush the tank. |
| Popping or rumbling noise | Sediment layer heating at the bottom | Flush the tank, assess its age. |
| Water at the base of the tank | Failed tank or loose fitting | Tighten fitting or replace the heater. |
| Rusty hot water | Anode rod spent, inner tank corroding | Replace anode or assess the tank. |
Many of these repairs are done in one visit. If the tank itself has failed, replacement is the honest answer, and we say so plainly.
Repair or replace: a simple rule
A heater that is under about ten years old and has a fixable part problem is usually worth repairing. A tank that is leaking from the shell cannot be repaired. When the repair cost approaches half the price of a new heater and the unit is aging, replacement makes more sense.
We give both prices when the choice is close, so you can decide with the numbers in front of you.

Call (949) 325-3122Hybrid, electric, gas and tankless units
Gas heaters rely on a pilot or igniter, a thermocouple and a gas control valve. Electric heaters use heating elements and thermostats. Hybrid heat pump models add a compressor and fan that need their own diagnosis.
Tankless units have different faults, such as scale on the heat exchanger or an error code from the control board. Our tankless water heater page covers flushing and service.
Hard water and your heater
Local water is very hard by USGS standards. The El Toro Water District reported 236 to 293 mg/L in its 2026 report, and Moulton Niguel Water District averaged about 16.65 grains per gallon in 2022.
Hard water leaves scale on elements and at the bottom of a tank. Flushing the tank each year and checking the anode rod help the heater last. A water softener reduces the scale that forms.
We repair water heaters in ZIP code 92654 and in 92653, and the same crew handles a swap if the tank is past saving. Tell the dispatcher your street address so we can confirm the ZIP before we book.
Code points that affect repairs
Laguna Hills publishes guidance for water heater work. It covers seismic strapping, expansion tanks on closed systems, the temperature and pressure relief valve, drain pans, combustion air and venting. A repair that exposes a missing strap or relief line is one we point out.
Ask the city's Building & Safety Division at (949) 707-2600 whether a permit applies to your repair. Work follows the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC).
Water Heater Repair questions, answered
Do you handle water heater emergencies at night or on weekends in Laguna Hills?
Yes. The line is open 24/7. Shut off the water supply to the heater if it is leaking, and call. We book a visit when a crew is available.
Why is my water heater leaking?
A leak from a fitting, valve or relief line can often be repaired. Water coming from the shell of the tank means the tank has failed and needs replacement.
Can you repair a gas water heater that will not stay lit?
Often yes. The cause is usually a worn thermocouple, a dirty pilot assembly or a gas control fault. If you smell gas, leave the house and call SoCalGas at 1-800-427-2200.
How old is too old for a repair?
Tank heaters commonly last eight to twelve years, and the shell corrodes with age. If the tank is old and leaking, replacement is the sound choice.
Do you repair tankless and hybrid heaters?
Yes. Tell us the brand and any error code when you call so the technician arrives prepared.
