Are water heater gas valves interchangeable?
Are water heater gas valves interchangeable? Water heater gas valves are not always interchangeable. Brand-specific valve styles and connections ensure gas flow to the pilot and burner matches the heater’s BTU output. Different fuel sources, like natural gas, propane, and oil-fired heaters, use different valves.

How does a millivolt gas valve work?
Millivolt Gas Valve This type of valve makes use of a standing pilot that continuously burns to heat a device, either a thermocouple or thermopile, which then produces a small amount of electricity – less than a single volt, hence “milli”-volt.
What does it mean when your pilot light won’t stay lit?
If your pilot light won’t stay alight, it might be the thermocouple. Sometimes dust buildup collects on the thermocouple and blocks the sensor. Try cleaning the thermocouple and then relighting the pilot light. If it continues to go out, the thermocouple might need to be replaced.
