Water Heater Repair Services in Los Angeles

Quick answer: Most "no hot water" calls on gas water heaters come down to the pilot light, the thermocouple or the gas control valve, and most of those are repairable. A leak from the tank itself is not repairable and means the heater needs replacing. Boss Plumbing repairs gas, electric and tankless water heaters across Los Angeles 24/7. Call or text (323) 464-4700.

Common water heater problems we fix

Pilot won't stay lit: usually a dirty or failing thermocouple or thermopile. See when to clean or replace your thermocouple.
Heater keeps turning off: thermocouple, venting or gas valve problems on gas units; a tripped high-limit switch on electric units.
No hot water or lukewarm water: burner, gas valve, dip tube or, on electric heaters, elements and thermostats.
Popping and rumbling: sediment on the bottom of the tank, often fixed with flushing.
Leaks: from the relief valve, drain valve or fittings (repairable) or from the tank (replace).
Rusty or smelly hot water: often a worn anode rod.

Repair or replace?

Repair usually makes sense when the heater is under about 8 years old and the problem is a part: a thermocouple, gas valve, element, thermostat, relief valve or drain valve. Replacement is usually the better value when the tank is leaking or rusting, or when the heater is past 10 to 12 years and needs a major part. We tell you which applies to yours before any work begins. If replacement is the answer, see our water heater installation page.

What to do while you wait

If the heater is leaking, turn off the cold water valve on top of the heater.
Turn the gas control to "off" or switch off the breaker for an electric heater.
If you smell gas, leave the house and call SoCalGas or 911 from outside.

Water heater repair in Los Angeles homes

Hard water is common in Los Angeles, and mineral sediment shortens the life of tanks, burners and elements. Garage and attic installations in the Valley also run hot in summer. Older homes may have heaters in tight closets with venting that no longer meets code. When we repair a heater, we also check the relief valve, venting and earthquake straps and let you know about anything unsafe.

Water heater repair questions, answered

Why do I have no hot water?

On a gas heater, check whether the pilot is lit. If it won't stay lit, the thermocouple is the most common cause. On an electric heater, check the breaker; a tripped breaker or failed element is common. If basic checks don't fix it, call or text us.

Why does my water heater pilot light keep going out?

A dirty or worn thermocouple, a weak thermopile, a draft, a blocked vent or a failing gas control valve can all put the pilot out. We test each and replace the failed part.

Is there 24-hour water heater repair in Los Angeles?

Yes. We take calls and texts 24/7 at (323) 464-4700, including nights, weekends and holidays.

How much does water heater repair cost?

It depends on the part and the type of heater. We diagnose the problem first and explain the price before any repair begins.

Can a leaking water heater be repaired?

If the leak is from a valve or fitting, usually yes. If water is coming from the tank itself, the tank has corroded through and the heater needs replacing.

Why does my hot water smell like rotten eggs?

That smell usually comes from a reaction between bacteria in the water and the tank's anode rod. Replacing the anode rod with a different type and flushing the tank often fixes it.

Do you repair tankless water heaters?

Yes. We descale, clean filters and sensors, fix ignition and flow problems, and clear error codes on tankless units. See tankless water heater services.

How long does a water heater last?

Tank heaters usually last 8 to 12 years. Regular flushing and an anode rod check help them last longer.
