Electric water heater is an A.O. Smith 40 gallon "low-boy" (short and fat)
about 10 years old. It's in a Florida condo unit, and from what I see, no
dielectric unions on the copper water lines to and from the heater. I see
a moderate amount of corrosion where the copper fittings connect to the
heater. No leaks. I don't see any rust or particles in the water at the
taps. I think it's a little slow to get hot water out, but not that
Since this is a winter vacation place and I won't be there 24/7 I'm a little
nervous about the tank letting loose when I'm not there, although it is on a
first floor slab and a drain pan is installed...
If I do replace it, dielectric unions are supposed to be used, correct?
Home Depot's selection all seem to have only a 6 year warranty which seems
to be on the low end. Consumer Reports said that brand doesn't matter, that
the warranty does, i.e., more years = heavier duty tank linings, insulation,
Your input appreciated !
