Hi, I came home from 3 days out of town to discover my expansion tank
had developed a pin size hole and had saturated padding and slab in
about 600 sq ft of my basement in addition to some baseboard and sheet
rock damage. The tank is almost 6 years old.

What is the normal life of one of these tanks and aside from coming
home to this situation every 6 years, what is the recommended method of
dealing with one of these tanks?

There isn't a floor drain in the basement, but I do have a water alarm
on the floor next to the water heater. Unfortuneately, the 3 neighbors
we usually have keep an eye on things for us were all out of town as
well(kids off from school). I have heard different opinions regarding
turning of the water to the entire house when leaving town. I usually
just turn off the line to the washing machine.

Thanks,

Jim
