Thats your best bet and funny that you say that. The week before closing on my house the town house complex i lived in blew one transformer after another. Thank god it was in the summer and I have a battery operated air pump and only a 65 gallon tank at the time. I was kicking myself the dam electric couldnt of held out another week. It was the second thing I did to my house after moving. Of course the tank came first, then upgraded the electric to 200 amp with the manual transfer switch and now 4 months later put in the generac auto. It is the best piece of mind knowning i dont have to worry about that. If i lost my tank i would be a dead man walking according to the misses anyway. LOL...
