Repair and replacement work
- A matching new tank when the old one leaks through its shell: same fuel and size, set in place on the existing water, gas and vent lines
- Full drain-and-flush to clear sediment from the tank bottom
- T&P relief valves tested, and replaced when they weep or won’t reseat
- Thermocouples, pilot assemblies and spark igniters on gas models
- Worn plastic drain valves swapped for sturdier ones
- Leaks traced at the flex connectors, dielectric nipples and shutoff on the cold line
- A yearly checkup: flame color, draft at the hood, the pan, and the temperature dial
Older houses, older water heater spots
San Gabriel’s homes run older than most in the region. The city’s 2021–2029 Housing Element preliminary report finds that 52.3 percent of its housing units are more than 60 years old, compared with 32.1 percent across the Southern California Association of Governments region. In houses that age, the heater often sits in a tight closet on a back porch or in a detached garage, with fittings that have been redone more than once.
Sediment is the slow problem in any tank. The U.S. Department of Energy’s Energy Saver guide advises: “Drain a quart of water from your water tank every 3 months to remove sediment that impedes heat transfer and lowers the efficiency of your heater,” and to follow the maker’s directions. Many tanks we see have never been drained at all, so the first flush takes patience.
Where our work stops
Repairs, upkeep and same-for-same tank swaps are ours. Running new gas pipe, changing or rerouting the vent, converting to tankless, or adding an electrical circuit goes to a plumber, gas fitter or electrician, and we tell you so straight away. If you ever smell gas, get everyone outside and call the gas company.
What to send us
Send a photo of the label on the tank, a photo of the pipes on top, and one of the pan or floor underneath, plus a short note on what is happening. Text it to (626) 684-3505.
Questions about water heater repair
When is a new tank the better choice?
When water is coming through the tank wall itself, or the burner side has rusted badly, repairs stop making sense. If the replacement can use the same spot and hookups, we swap it in one visit: drain, disconnect, set the new tank, reconnect, fill, light and test for leaks. If it needs anything different, we point you to the right trade.
The tank pops and rumbles when it heats. Is it about to fail?
Not necessarily. That sound is usually water trapped under a layer of sediment, boiling as the burner runs. A thorough flush often quiets it, and we tell you what came out of the tank.
How do I know if the relief valve is bad?
Water dripping from its discharge pipe when the heater has not been used, or a valve that will not snap shut after a test, both point to a worn valve. We check the temperature setting too, since an overheated tank can make a good valve open.
Can you relight my pilot?
Yes, and we look at why it went out. A dirty pilot tube, a weak thermocouple or a draft from a nearby door are the usual reasons, and each has a different fix.
Do you work on electric water heaters?
For leaks, relief valves, drain valves and flushing, yes. Electrical faults inside an electric heater go to an electrician.
Is a yearly checkup worth it?
For an older tank, a once-a-year flush and valve test is the simplest way to catch a small problem before it turns into a flooded closet.
