Hello, I have an older copper cylinder consisting of 2 tanks - a large one at the base and a smaller one on top.
The top tank was rising and exiting the overflow, and I noticed the ball cock valve was not shutting off completely (drip, drip). I have replace this.
My concern is now, is there another way for it to overflow?
How does this configuration work? The element is in the base tank only. How is the base tank fed cold water - from the top tank or vice versa?
I assume the heated water in the bottom tank expands and goes where?
I noticed in the top tank a second exit pipe, not sure if this goes to the bottom tank or another overflow?
Confused :-$
