: I have been having problems with the pilot light on my gas boiler this winter. I have woken up in the morning numerous times to find that there is no heat and the pilot is out. We have had the thermocoupler and the gas valve replaced but the problem persists. What else could be the problem? The pilot on the water heater stays lit, and there doesn't appear to be a flicker in the pilot light flame which would indicate low pressure. Any ideas?
The only thing i can think of is dirt in the pilot tube. Also have your gas company check your gas regulator at the meter. Dale's Plumbing Service INC LMP
