what the tank looks like on the inside.

I bet it's 98% solid with just a 1" path somewhere inside.

Depends on what the water is like. I checked out my unit when it was 13
years old, there was a little bit of crud sitting in the bottom but
hardly significant, less than a handful. Not much in the way of minerals
in my water.

I bought an old house and replaced the WH several lyears later. Have
no clue as to the age of the tank but it was a bunch. I cut it up for
a stock water tank. Only a bit of red sludge in it.
