Gas control valve in water?
If water rises near the bottom of a gas control valve as shown below by the red line in a flood, is the valve considered submerged and is it compromised?

Probably not, but no guarantees. Needs to be disconnected, drained, dried out...Another inch......A gas professional with experience shlupd be doing this...serious business Mad Dog 🐕

Thermocouple, pilot and main out to burner were all immediately disconnected to remove burner assembly for drying.
Except for what looked like some old pre-existing corrosion on thermocouple compression nut, No moisture or water noticed...

"Actually"
I see two little wires that look "pressed in" above the thermocouple connection. I'm wondering where/if there are orifices that would allow water entry on the unit.

the insulation in the tank must have gotten wet also?
Salt water? How old is the tank?

The insulation did get wet but only soaked less than an hour or so.
No salt water, living above 1000 ft.
I immediately removed the burner assembly and blew it out thoroughly with compressed air.
Tank is 11 years old.

Hi, If this is your own heater, it's your choice. If this were a client's water heater, you could not ethically subject them to the risk.

I am not a lawyer, and you should certainly change the valve.
If the water stopped where the line is, I wouldn't worry about it if it were in my house. If it were Grandma's house, or I was on the clock at work, I'd replace it.

Thank you. Yes it is mine.

Can someone tell me what the typical and worst case scenario is when these gas valves are defective from flooding?

Dude...if your calling them "wires" you're not trained or qualified to be working on the gas valve. Not a DIY project. Mad Dog 🐕

I have done my own remodel plumbing and installed a gas water heater before with professional sign offs.
What am I supposed to call them, thermocouple spaghetti, leads?

Could they be wires to the "sparker" run by the clicker button on the gas valve to light the piolet?
0 -
No they are coming from above the thermocouple fitting and run into the control unit.

Hi, Those wires likely go to a non resettable high limit.

Is that for transducer "over-voltage"?
