Water Heater Pilot Light Out in San Diego — Step-by-Step Fixes
A water heater pilot light goes out in San Diego more often during cold snaps and after nearby gas utility work. Most relights take 5 minutes following the label on your unit. If it keeps going out within 24 hours, that's a thermocouple issue — a $20 part and about 30 minutes of plumber labor.

Why does my water heater pilot light keep going out in San Diego?
The most common cause is a failing thermocouple — the small sensor that tells the gas valve the pilot is lit. When it wears out, it cuts gas to the pilot as a safety measure. A plumber can replace it for $150–$300 including parts. If the pilot won't stay lit even after thermocouple replacement, or if the unit is over 10 years old, a full water heater replacement ($900–$2,200 installed) is usually the better call.
