Water heater repair in Sacramento, CA for gas and electric tanks
No hot water is usually one part, not a whole new heater.
We test the thermocouple or flame sensor, gas valve, igniter, burner, elements and thermostats, then replace the failed part. If the tank itself is leaking, repair is over and we price a replacement.
What water heater repair covers
Gas water heaters most often fail at the pilot assembly, the thermocouple or flame sensor, or the gas control valve. Electric heaters usually fail at an element or thermostat. All of those are repairable, and our trucks carry the common parts.
A leaking tank is different. If water is coming from the tank body or the bottom seam, the glass lining has failed, and no part will fix it. We tell you that plainly and give you replacement options the same visit.
Signs it is time to call
- Pilot will not stay litA worn thermocouple, flame sensor or dirty pilot.
- Lukewarm waterSediment over the burner, a failed element or a broken dip tube.
- Popping or rumblingSediment on the tank bottom boiling under the burner.
- Rusty hot waterCorroding tank or a spent anode rod.
- Water around the baseCould be a fitting or relief valve, or a failed tank.
Most part replacements fall here. A leaking tank means replacement, priced separately. Every price is confirmed on site before work starts.

Water Heater Repair in Sacramento: what we see locally
Most water heaters in Sacramento-area homes sit in the garage, where summer heat and winter cold are hard on controls and venting. We check vent connections and combustion air on every gas heater call.
Most no-hot-water calls end with a single replaced part and a sediment flush.
California requires water heaters to be strapped against earthquakes. If your straps are missing or loose, we fix them while we are there.
What you can safely do before we arrive
- If the tank leaks, close the cold supply valve on top.
- Set a gas heater to pilot or switch off an electric heater's breaker.
- Clear space around the heater.
Water Heater Repair questions
How long should a water heater last?
Tank heaters typically last 8 to 12 years. Hard water and skipped flushing shorten that.
Is it worth repairing a 10 year old heater?
For a simple part on a dry tank, often yes. If the tank is rusting or leaking, put the money into a replacement.
What does the relief valve do?
It opens if pressure or temperature gets too high. If it drips, it may be worn or your pressure may be too high, and both need attention.
