A. O. Smith water heater repair in Pasadena

Begin at the rating plate stuck to the tank. Model, serial number and capacity are printed there, and they unlock everything else. A. O. Smith serials generally begin with the year and week of manufacture, so a number starting 2038 means week 38 of 2020. Age plus symptom decides whether a repair is worth the money. Plenty of faults are small parts. A tank with a hole is not.

The swap side lives on our water heater replacement page. Here the subject is keeping an A. O. Smith unit going, and spotting the point where that stops paying off.

How do I tell how old my A. O. Smith water heater is?

Read the serial number on the rating plate. Current A. O. Smith serials start with two digits for the year and two for the production week, so 1719 means week 19 of 2017. Older units used other formats, such as month and year first, so an older plate may need a decoder or a call to the manufacturer. The date is when it was built, not when it was installed.

Brands made by the same company, including State, American and Reliance, use the same style of serial number, and so do some Whirlpool and Kenmore-branded units. If the plate is rusted or unreadable, a plumber can usually estimate age from the design, but a guess isn't a record.

Age counts because the federal Energy Department says storage tanks serve for 10 to 15 years. Beyond the decade mark, spending a few hundred dollars on a repair becomes a closer decision; how often water heaters get replaced digs in.

What commonly goes wrong with an A. O. Smith heater?

Typical faults: a thermocouple or pilot issue on gas models, a dead element or thermostat on electric ones, a spent anode rod, a weeping relief valve, sediment, and leaking fittings. Each shows its own symptom, and most can be fixed with the tank staying put.

Here is the pattern by symptom:

The thermocouple is the textbook gas-heater repair. When the flame keeps dying, it is a frequent culprit, and the part itself is cheap, so labor and the gas safety check make up most of the bill. Details are on our thermocouple replacement page.

Local water is very hard, near 13 grains per gallon in recent reports, which feeds sediment on the tank floor and crusts electric elements. A rumbling heater should make you suspect scale.

Can I fix an A. O. Smith water heater myself?

A careful homeowner can check the thermostat setting, relight a pilot using the instructions printed on the heater, or flush sediment. Gas work, relief valve replacement and electrical repairs are another matter. Gas piping and gas valves go to a contractor holding the state license.

Gas odor means no relighting anything. Get outside, then ring the gas company, SoCalGas, on 1-800-427-2200; 911 is for anyone in immediate danger. Their safety steps are at socalgas.com. Never plug a dripping relief valve: it exists to protect the tank. Why gas valves are contractor territory is covered in gas valve replacement.

On electric models, kill the breaker before touching an element or thermostat and confirm the wires are dead. If that sounds unfamiliar, hire it out. Scalding is the other hazard, so keep the thermostat within the manual's recommendation.

Is my A. O. Smith heater still under warranty?

Check the rating plate date and the warranty card. A. O. Smith's residential tank warranties come in several tiers, with 6 years the usual entry level, and many cover the tank and parts for that period with labor covered for a shorter time, if at all. With no receipt, the warranty clock may run from the manufacture date on the plate, so the serial decode matters.

Details vary by model, so read the document for yours. A commonly cited condition is that the warranty shortens when a heater is used for anything other than a single-family home. Warranty claims usually require proof of purchase and often an installation that followed code, including any required permit, so keep the paperwork from whoever installed it.

A warranty may replace a defective part or tank without covering labor, and it won't cover damage from scale or neglect. Ask the plumber who diagnoses the problem to note the model, serial number and fault in writing so you can file.

When should I repair and when should I replace?

Repair when the unit is younger than about ten, nothing leaks from the shell, and the fault is a part: thermocouple, element, thermostat or valve. Replace if the tank itself weeps, the heater is past 12 to 15 years, or repairs keep stacking up. Failing steel can't be patched.

Our rule of thumb:

• Under 8 years, small part failed: repair.
• 8 to 12 years, one repair: repair if the tank is sound, but budget for a replacement soon.
• Over 12 years, or any tank leak: price a replacement and compare.

Two realities help. Sinking most of a replacement's cost into repairs on an old tank is hard to defend. And a replacement triggers today's rules: Pasadena wants a plumbing permit, its Building and Safety Division checks the location, and state law has tank heaters strapped for earthquakes. Numbers are on the water heater replacement price page.

Brand-specific repair pages exist for other makers too, such as Rheem gas water heater repair.

What is the way to book an A. O. Smith repair in Pasadena?

Tell us the symptom, the model and serial numbers from the plate, and the fuel, and ask for a visit. A local plumber we arrange examines the heater, names the fault, and writes up a price ahead of the work. A photo of the plate and of any leak helps.

The quote page takes those details, plus where the heater sits (garage, closet, attic) and whether water or gas is already shut off. Pasadena Pipe Works serves Pasadena and the San Gabriel Valley, and our home page has the remaining services. Completely cold taps? Start with the causes of no hot water.
