The anode was replaced Feb 2017. At the time the water heater was 11 years old. Picture is recent. Now the water heater is 14 years old. It has a bad gas valve or controller. The pilot will light but not stay on. Thermocouple tested fine as did the thermal switch. Also, there is a dribble coming from the pressure relief valve. I am looking at either buying a new controller and relief and fixing this heater or at this point just buying a new one.
It’s in the garage so shouldn’t cause too much damage. However, if the rusty burner also means the tank is probably rusting, then instead of putting the work and parts into it I am just going to buy a new heater.
I am curious if rusting in the burner is part of the normal aging process or if it indicates other issues.
