Just replaced the thermocouple on gas fired water heater because the old one would not keep pilot light lit.
Is there a certain distance the end of couple should be from the other part beside it?
I cleaned out all the stuff from under the tank and the burner plate so nothing in there I can see.
It lights up fine, but I can see the tip of the couple is red...and a lot of heat seems to be generated from the area all the piping is by the little hatch way.
The tank may of been cold all night. Not sure. Had hot water last night, wife went to take bath, no hot water, and the tank was cold with no pilot light.
also a bit of sizzling noise like water on a hot spot but no water leakage anywhere
Update: OK shut it all down, removed, adjusted the thermocouple because the package says flame to cover 3/8 in of it...
Now it seems to not glow red, and not sure how the flame should be looking from the burner, kind of yellow with a tinge of blue?
Still hear sizzling which when I took out the unit, the plate was a bit wet, no water dripping, but damp in the inside tube thing..
may be time to look to replace.?

Coming back to where you started is not the same as never leaving
