I have a Rheem water heater, 50 gal, aprox 5 years old. Within last month I had to replace the thermocouple, worked fine until this week, now I notice that the pilot light is about 3 inches hight and there is flame coming from the bottom of the pilot burner from the air inlet. My gas valve is a robertshaw 66-148-308 and has no pilot light adjustment. Does that mean the pressure is too high if the flame is 3 inches high and shooting out the air intake, and should i replace the valve, or as ive heard should i just replace the water hearter due to cost of new valve.
any advice about this problem would be appreciated.
thanks Hal
