I have a gas leak in the gas regulator of my 50 gal water heater. I plan to replace the gas regulator on the water tank as the most cost effective fix, something I have never done before. I shut off the gas, disconnected the gas line, and burner, pilot, thermostat assembly. I am now ready to remove the regulator/thermostat.
I assume I need to shut off the water and drain the tank first. Is this correct ?
Does the regulator/thermostat just screw in like a pipe thread ? that is do I just unscrew the regulator to remove it ?
Thanks for any help.
