Pros: None at all
Cons: Lent and fluke issues.
My A.O. Smith heater is only 5 years old. In that short span of time I have had to have the pilot assembly replaces, serviced twice, pulled off its base and serviced, it has cost me fee to have the dryer vent cleaned as well as the fluke. This has all been down at various times in a 3 year period. I have been told that each item is required to keep the pilot light on. I now live life constantly checking that the pilot light is on and wondering what the next course of action might be.
I do not recommend that this water heater is purchased.
