What's Wrong With Your Water Heater?

Most water heater problems fall into a handful of patterns. Here’s what you’re seeing, what usually causes it, and how we fix it:

What’s happening

Usual cause

Typical fix

No hot water at all (gas)

Pilot out, bad thermocouple or igniter, failed gas valve

Replace thermocouple, igniter or control valve

No hot water at all (electric)

Tripped breaker, burned-out element or thermostat

Replace element or thermostat

Hot water runs out fast

Sediment buildup, failed lower element, broken dip tube

Flush tank, replace part

Popping, rumbling or banging

Hard water scale baked on the bottom of the tank

Flush; descale; consider a softener

Water leaking from the top

Loose fittings or a leaking T&P relief valve

Tighten or replace valve or fittings

Water leaking from the bottom

Tank is rusted through

Replace the water heater

Rotten egg smell from hot water

Reaction with the anode rod

Replace anode rod, flush tank

Rusty or brown hot water

Tank corroding inside

Anode rod now; replacement soon

Tankless error code or cold bursts

Scale, dirty filter, igniter or sensor issue

Descale, clean, replace part

If your tank is leaking from the bottom, a repair won’t help; the steel tank itself has failed. Everything else on this list is usually fixable.

Should You Repair or Replace Your Water Heater?

We’ll give you an honest answer, even when repair is the cheaper option for you. Here’s the rule of thumb we use:

Repair it if…

Replace it if…

A tank is under about 8 years old, or tankless under 15

A tank is 10–15 years old, or tankless near 20

The tank isn’t leaking

Water is leaking from the tank itself

The repair costs less than half of a new unit

The repair costs half or more of a new unit

It’s the first problem in years

It keeps breaking down

Not sure how old yours is? The serial number on the label usually shows the year. Send us a photo of the label and we’ll tell you.

Need a New Water Heater Today? Same-Day Replacement

If your water heater has failed, you may not want to wait several days for hot water. We install common 40- and 50-gallon gas and electric tank models. Same-day replacement may be available, depending on stock, scheduling, and installation requirements.

Your replacement may include:

  • Removal and disposal of the old water heater
  • Required permits and inspections
  • Earthquake straps
  • A thermal expansion tank when required
  • New water and gas connections where needed
  • A properly installed temperature and pressure relief valve
  • Venting and safety checks for gas units
  • Final leak and operation tests

We explain what your home needs and provide a clear price before work begins. Additional repairs or upgrades will be discussed before they are added to the job.

Tank, Tankless or Heat Pump: Which Is Right for You?

Type

Best for

Lifespan

Installed price (LA)

Gas tank (40–50 gal)

Fast, budget-friendly replacement

10–15 years

$1,800 – $3,500

Electric tank (40–50 gal)

Homes without gas

10–15 years

$1,600 – $2,800

Tankless gas

Endless hot water, saving space

Up to about 20 years

$3,500 – $6,500

Heat pump (hybrid)

Lowest energy bills for electric homes

10–15 years

$3,500 – $6,000

Switching from a tank to tankless often needs a bigger gas line and new venting, which is why conversions land at the high end. Heat pump models may need a dedicated electrical circuit and a space with good airflow, like a garage.

Tankless Water Heater Repair and Installation

We repair and install Rinnai, Navien, Noritz, Rheem and other tankless brands. Most tankless problems in the Valley come from hard water scale, so a yearly descale keeps them running and protects the heat exchanger. If you’re thinking about a new gas tankless unit, ask us first: South Coast AQMD Rule 1146.2 phases some gas tankless units toward zero-emission models over time.

What Changed for LA Water Heaters in 2026?

Rules and rebates shift often, so here’s where things stand right now:

  • Gas tank water heaters are still allowed in LA. In June 2025, the South Coast AQMD board voted 7–5 against new rules that would have pushed homes away from gas water heaters.
  • Federal tax credits for heat pump water heaters ended after 2025. Local utility and state rebates may still be available; we’ll help you check what applies to your home.
  • A federal efficiency rule starts May 6, 2029. After that date, new electric tank water heaters over 35 gallons must be heat pump models. If you have an electric tank, your next replacement may look different.

What Does LA Code Require for a New Water Heater?

A water heater swap isn’t just plumbing; it’s a safety installation. Los Angeles requires a permit for most replacements, and California requires water heaters to be strapped so they can’t tip over and break gas or water lines in an earthquake. Many homes also need a thermal expansion tank to absorb pressure from heated water, and every heater needs a properly piped temperature and pressure relief valve. Gas units need correct venting and a sediment trap.

That’s also why a cheap Craigslist install can get expensive: unpermitted work can cause problems with insurance or when you sell your home. We handle all of it.

How Does Same-Day Water Heater Service Work?

Step 1 — Call or book online

Tell us what's happening; a photo of the label helps.

Step 2 — We arrive and diagnose

We test the gas or power, controls, tank and connections.

Step 3 — You get your options

Repair or replace, each with a clear written price. Your $75 is credited either way.

Step 4 — We do the work

Most repairs take 1–2 hours; most tank replacements are done in 3–5 hours.

Step 5 — We test everything

We check operation, connections, leaks, and applicable safety features.

Step 6 — We clean up

When replacement is included, we remove the old unit if that service is part of the agreed job.

Most repairs run 150–700 depending on the part. Our diagnostic is $75 and is credited toward the repair.

A new gas tank water heater usually costs 1,800–3,500 installed, including the permit, straps and expansion tank. Tankless runs 3,500–6,500; heat pump models 3,500–6,000.

Yes, if the tank is under about 8 years old, isn’t leaking and the repair costs less than half of a new unit. Otherwise, replacement is usually the better value.

Tank water heaters usually last 10–15 years with care. Tankless units can last about 20 years. Hard water in parts of the Valley can shorten that without regular flushing.

Yes. The South Coast AQMD rejected new rules for home gas water heaters in June 2025, so gas tank models are still allowed.

It’s usually a reaction between your water and the tank’s anode rod. Replacing the anode rod and flushing the tank typically fixes it.
