Suburban Water Heater Gas Control Valve

[Bluedog]

Has anyone removed the thermostatic gas control valve on a 10 gallon Suburban water heater?

I am in the process and it appears it is like the drain plug that has the threads all full of rust when removed. This is probably worse yet as it has never been removed.

I am in the process of using PB Blaster but if anyone has a better solution would like to hear it.

If this is the type of gas valv3e you are asking about.....



PB Blaster, Liquid Wrench etc .....liberally spray/soak it

Try to tighten slightly then unscrew it using a LARGE Channel Lock Pliers...grab body of gas valve with pliers
