Replacing A Water Heater
I don't even want to know
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.
