Gas Water Heater Repair FAQ
Common Questions
Why won't my gas water heater light?
Common causes include a failed thermocouple, dirty pilot assembly, bad gas valve, or a draft blowing out the pilot. A licensed plumber can diagnose and repair the issue safely.
Can I smell gas near my water heater?
If you smell gas, leave the area immediately, do not flip any switches, and call your gas company’s emergency line. Gas leaks are dangerous and should be handled by professionals only.
Costs & Pricing
How much does gas water heater repair cost?
Check the Fair Price Guide on HomeRepairRates.com
Is it worth repairing a gas water heater?
If the unit is under 8 years old and the repair is straightforward (thermocouple, pilot, gas valve), repair makes sense. If the tank is leaking or the unit is over 10 years old, replacement is usually better.
How often should a gas water heater be serviced?
Annual maintenance is recommended. This includes flushing the tank, checking the anode rod, testing the pressure relief valve, and inspecting the burner and venting.
