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, etc.
Your input appreciated !
