A pilot light that won't stay lit on a gas water heater is a common complaint, and while it can sometimes be a simple relight, a pilot that keeps going out repeatedly usually points to one of a few specific underlying causes worth understanding before you keep relighting it.
The thermocouple is a small safety sensor that detects whether the pilot flame is lit and keeps the gas valve open accordingly. When it wears out or gets dirty, it can falsely signal that the pilot is out (even when it's lit), shutting off the gas supply as a safety measure. This is one of the most common causes of a pilot that won't stay lit and is a relatively inexpensive, straightforward repair.
If the water heater is in a garage, closet, or utility area with airflow from outside, drafts can blow the pilot flame out, especially during windy weather. This is worth ruling out if the pilot goes out primarily in certain conditions rather than consistently.
Dust and debris can build up in the small opening the pilot gas flows through, restricting flow enough that the flame is weak or unstable. This typically requires cleaning by a professional, since the opening is small and easily damaged.
If the thermocouple and other simpler causes have been ruled out, the gas control valve itself (which regulates gas flow to both the pilot and main burner) may be failing. This is a less common cause but typically means the valve needs replacement rather than repair.
We'll diagnose the cause and get your hot water back reliably.

It's a relatively straightforward repair for a licensed technician, but because it involves gas components and safety systems, professional replacement is the safer route.
If the water heater is in a drafty garage or utility closet, airflow from outside can blow the pilot flame out. This points to a draft issue rather than a component failure.
The safety shutoff behavior itself is working as intended — it's a protective measure. But repeated relighting attempts without diagnosing the root cause isn't a long-term solution and should be professionally addressed.
From thermocouples to full water heater replacement, we've got it covered.
