- Water leaking from the tank body means the lining has failed; leaks from valves and fittings are usually repairable.
- California requires residential water heaters to be braced, anchored or strapped against earthquakes [1].
- The U.S. Consumer Product Safety Commission recommends a 120°F setting for most households [2].
- Replacing a water heater in the City of Los Angeles is permitted work through LADBS [4]; check any contractor's licence with the CSLB [3].
Symptom finder
What is your water heater doing?
Start with the symptom. Each tile opens a guide that narrows down the likely cause before anyone opens a panel.
No hot water at all
On gas units, usually the pilot, thermocouple or gas control. On electric units, a tripped reset switch or a failed element.
Read moreHot water runs out fast
Sediment taking up tank volume, a broken dip tube mixing cold into the outlet, or one of two elements out.
Read moreWater around the base
Fittings and valves can be fixed. A seep from the tank shell itself means the lining has failed.
Read morePopping or rumbling
Water trapped under a crust of mineral sediment boils in bursts. A flush can help on younger tanks.
Read moreRusty or smelly hot water
Often a spent anode rod. Caught early, the rod can be replaced before the tank corrodes.
Read moreTankless error code
Codes are brand-specific; scale, gas supply and venting are the usual suspects.

Anode Rod Replacement
The anode rod is what keeps a steel tank from rusting. Checking and replacing it is one of the few repairs that can add years to a water heater.

Gas Control Valve Replacement
The valve on the front of a gas water heater controls both the gas and the water temperature. When it fails, the burner won't fire or won't stop.

Heating Element & Thermostat Replacement
No hot water or hot water that runs out fast on an electric heater usually comes down to a failed element or thermostat.
Explore service
Relief Valve (T&P) Replacement
A dripping or untested temperature and pressure relief valve is a safety issue. Find out why it opens and when it needs replacing.
Explore service
Thermocouple & Pilot Assembly Replacement
When a gas water heater pilot lights but will not stay lit, a worn thermocouple or pilot assembly is the usual cause.

Smell gas, or water spreading fast?
Do these first. A repair can wait until the situation is safe.
- Gas smell: leave the house without flipping switches, then call 911 and your gas utility from outside.
- Active leak: close the cold-water valve on the pipe above the heater, then shut off power or set the gas control to Off.
- Hissing or steam from the relief valve: keep clear of the discharge pipe and turn the heater off.
Diagnosis
What usually goes wrong, and what it tells a plumber
Most water heater calls fall into a handful of patterns. No hot water at all on a gas unit often traces back to the pilot, the thermocouple or the gas control valve. On an electric tank it is more often a tripped high-limit switch or a burned-out heating element. Lukewarm water that runs out quickly tends to mean sediment has built up in the bottom of the tank, a dip tube has broken, or one of two electric elements has failed.
Water on the floor is the symptom to take most seriously. A drip from the relief valve's discharge pipe can be a valve doing its job because pressure or temperature is too high. A slow weep from a fitting can usually be tightened or replaced. Water seeping from the tank body itself almost always means the inner lining has corroded through, and no repair reverses that.
Describing what you see and hear on the phone lets the plumber arrive with the right parts instead of making a second trip.

The visit
How a repair visit normally goes
Every contractor runs their visit a little differently, but a competent water heater repair follows this shape.
- 1
Describe the problem
Have the heater's brand, fuel type and the age from its rating plate handy. Photos of the label and any leak help the plumber prepare.
- 2
On-site diagnosis
The plumber checks the gas supply or electrical circuit, the burner or elements, the venting and the relief valve before naming a cause.
- 3
Repair and test
After the fix, the heater is run through a full heating cycle and checked for leaks, proper draft and a safe temperature setting.

Repair or replace
Repair it or replace it?
The age of the tank and where the failure is matter more than how dramatic the symptom looks.
| Situation | Usually repairable | Usually time to replace |
|---|---|---|
| Pilot will not stay lit | Thermocouple, pilot assembly or gas valve | Ask the plumber on the visit |
| No hot water (electric) | Element, thermostat or reset switch | Repeated element failures from heavy scale |
| Water around the base | Leaking drain valve, relief valve or fitting | Leak from the tank body or seams |
| Rumbling or popping | Sediment flush on a younger tank | Heavy sediment on a tank past roughly ten years |
| Rusty hot water only | Anode rod replacement if caught early | Rust plus leaks or a tank well past its warranty |
Age matters because tank linings wear out from the inside; the manufacture date is encoded in the serial number on the rating plate.
Los Angeles specifics
Los Angeles details that change the job
California law requires residential water heaters to be braced, anchored or strapped to resist falling or moving during an earthquake. [1] Many older installations in Los Angeles have one loose strap or none at all, so a careful repair visit includes a look at the strapping, the flexible gas connector and the seismic shut-off valve if one is installed.
Replacing a water heater inside the City of Los Angeles is permitted work through the Department of Building and Safety, and other cities in the county run their own building departments. [4]
Water hardness in Los Angeles varies by neighborhood because the city blends water from several sources. Harder water leaves more scale in tanks and in the heat exchangers of tankless units, which is one reason flushing intervals that suit one house may be too long for another.

Can I relight the pilot myself?
If you follow the lighting instructions on the heater's label and there is no gas smell, relighting is a normal homeowner task. If the pilot lights and then goes out again within a minute or two, the thermocouple or flame sensor is the usual suspect and needs a repair rather than repeated relighting.
Is a leaking water heater dangerous?
The water is the main risk to floors, drywall and anything stored nearby. A relief valve that is discharging, however, is a warning that temperature or pressure has gone too high, so turn the heater off and have it checked rather than capping the pipe.
What temperature should the water heater be set to?
The U.S. Consumer Product Safety Commission recommends 120°F for most households [2]. It reduces scalding risk and standby energy loss. Some households with specific needs set it higher and add mixing valves at fixtures.
