Overview
Gas water heaters usually lose hot water because the pilot, thermocouple, flame sensor or gas valve has failed. Electric models burn out elements or thermostats. A tank that rumbles is boiling water trapped under a layer of sediment, which our hard water leaves behind. A puddle may be a drain valve or relief valve, which can be replaced, or the tank, which cannot.
We test each part instead of guessing, then tell you what is wrong, what it costs to fix and how much life the tank likely has left. If a repair makes sense, we do it on the spot from parts on the truck. If the tank is near the end, you get a replacement price to compare.
How we handle it
Test the system
Ignition, controls, elements and thermostats checked one by one.
Check the tank
Age, sediment, corrosion and where any water is coming from.
Repair or compare
Fix the part, or give you both prices side by side.
What it costs
Thermocouples, elements and thermostats are inexpensive parts, so most repairs are mostly labor. Gas control valves cost more. When a tank is old enough that the repair is a large share of a new heater, we show both numbers.
Good to know
- Flush the tank once a year to clear out sediment.
- Test the relief valve by lifting the lever briefly; it should snap shut afterward.
- Keep two feet clear around a gas heater so it gets combustion air.
Garage water heaters are standard in most northwest side homes, which makes repairs quicker than in attic installs. Make sure nothing is stored against the burner door.
Water heater repair questions
Is my heater worth repairing?
Most of the time, if the tank is dry and younger than roughly eight years.
Why is my hot water running out fast?
Sediment, a failed lower element, or a broken dip tube are the usual causes.
Can you fix any brand?
Yes, all major brands, gas and electric.
What temperature should my heater be set to?
Around 120 degrees suits most homes. It is hot enough for comfort and lowers scald risk and energy use.
