Yes, gas flow shuts off automatically when the pilot light goes out. Modern water heaters are equipped with a crucial safety component called a thermocouple. When the pilot flame is lit, it heats the thermocouple tip, generating a tiny electric current that keeps the gas safety valve open. The moment the pilot blows out, the thermocouple cools down, the electrical current stops, and the safety valve snaps shut, stopping all gas. Verification: Ensure the burner does not emit gas or ignite when the pilot is unlit.
