The pilot light in our new (~2 y.o.) water heater (a State Select High Efficiency) keeps going out, a couple times a day. The problem just started a few days ago when the rains started. I don't think it's a thermocoupler problem because the pilot light easily lights, and I don't think it's a combustion air problem because it's in our laundry room, not in a closet, and is open to the entire inside of the house. The unit was installed professionally with good ducting, earthquake strap, spill pan, etc.
So I'm wondering what else might be causing the light to go out. I'm wondering if it's possible that we're not getting enough pressure. The water heater is the last appliance on the gas line, after the wall heater and the stove. Is it possible that the pilot light goes out intermittently if the other things are in use? And if so, how would I diagnose low pressure? And what other causes might it be?
