Water Heater Service, Repair & Replacement

A water heater rarely fails without warning. It gets slower to recover, noisier, or starts leaving rust in the hot side long before it leaks. Catching it at that stage is the difference between a planned replacement and a flooded utility closet.

Water heaters are the single most common source of interior water damage in occupied buildings, and almost every one of those failures was visible months earlier as a performance change rather than a leak.

That is the whole argument for treating hot water as a maintained system rather than an appliance you replace when it dies.

Warning signs

Hot water runs out faster than it used to, or takes longer to recover between uses
Rumbling, popping or kettling sounds from the tank
Rusty or cloudy water on the hot side only
Water pooling under or around the unit, or staining on the pan or floor
The temperature-and-pressure relief valve discharging
A tankless unit short-cycling, error-coding, or delivering inconsistent temperature
A unit past its expected service life, especially in a finished or occupied space

What RePlumbify inspects and performs

Diagnose no-hot-water and inconsistent-temperature complaints on tank and tankless systems
Repair or replace thermostats, elements, gas control valves, igniters and relief valves
Replace tank water heaters, including code-required seismic strapping, expansion control and venting
Install and service tankless units, including descaling and flushing
Service recirculation systems, pumps, timers and dedicated return lines
Replace or install expansion tanks and pressure-regulating valves where required
Flush and inspect tanks, and replace sacrificial anode rods, as scheduled maintenance

What to expect

You tell us the symptom and the unitA photo of the data plate saves a visit's worth of guessing — it tells us fuel type, capacity, age and venting.
We confirm a service windowRequested windows are proposals until dispatch confirms them.
We diagnose before quotingA failed thermostat and a failed tank cost very different amounts. We establish which one you have.
You approve repair or replacement in writingIf replacement is the recommendation, you get the reasoning: age, condition, failure mode, and what a repair would realistically buy you.
We install to code and document itSeismic strapping, expansion control, venting, relief-valve discharge and combustion air are part of the job, not extras.

Residential and commercial

For homes and condominiums. For a home, the two decisions that matter are tank versus tankless and where the unit lives. A tankless conversion is not automatically the better answer — it depends on gas line capacity, venting, fixture demand and how the household actually uses hot water. We will give you the honest version rather than the upsell.

For commercial and multifamily buildings. For multifamily and commercial buildings, hot water is a habitability and an operations issue. We can inventory units by building, document age and condition, and put replacements on a planned schedule instead of an emergency one.

Safety first

A discharging temperature-and-pressure relief valve is a safety device doing its job. Do not cap it, plug it, or tie it off — have the cause diagnosed.
Do not relight a gas appliance if you smell gas. Leave the building and call the gas utility from outside.
Water heater replacement in California requires code-compliant seismic bracing, venting and expansion control. Work that skips these is a safety and resale problem, not a saving.

1-Year Limited Workmanship Warranty

We warrant our workmanship for 12 months from completion. Covers our labor — equipment and parts carry the manufacturer's own warranty, which we pass through to you. Drain and sewer clearing is warranted 30 days and is excluded where a camera shows roots, a collapsed or offset line, or a structural defect. Other exclusions apply, including customer-supplied fixtures, pre-existing conditions, work by others, misuse and normal wear. Covers the original customer at the original service address; not transferable to a new owner. This warranty adds to your rights under California law and does not limit them.

Paying for a large project

A repipe, a sewer replacement or a full water-service line is a planned expense, and it does not always land at a convenient moment. On projects at roughly $10,000 and above we are willing to discuss a payment arrangement. Raise it when we scope the work and we will tell you plainly what is possible.

On home improvement work, California limits any deposit to the lesser of $1,000 or 10% of the contract price, and payments after that follow work actually completed. We do not ask for more than the law allows, on a job of any size. Any payment arrangement is agreed case by case, in writing, as part of the contract for the work. RePlumbify does not advertise credit terms, does not pre-approve anyone, and makes no representation that a payment arrangement will be available on a given project. Nothing on this page is an offer of credit or a commitment to extend credit.

Questions

Water Heaters — frequently asked

How long should a water heater last?

It varies widely with water quality, maintenance history and how hard the unit works. Rather than quoting an average, we look at the specific unit — anode condition, sediment, corrosion at the fittings, and the failure mode you are describing — and tell you where yours actually is.

Is tankless worth it?

Sometimes. It depends on your gas supply, venting path, simultaneous fixture demand and how long you plan to keep the property. It is a genuinely better answer for some buildings and an expensive lateral move for others. We will tell you which one you have.

Can you replace a water heater in an upstairs closet or over finished space?

Yes, and those installations are exactly where pan, drain, leak detection and correct expansion control matter most, because the failure mode is water in the ceiling below.

Do you service the unit I already have, or only replace it?

We repair and maintain as well as replace. Flushing, anode replacement and descaling on tankless units meaningfully extend service life, and that is cheaper for you than a replacement cycle.
