This is my theory. With which I am happy.
Toilet tanks are attached to the pipes by metal clamps etc. There is a
rubber washer or whatever. (I am too lazy to go look at the toilet right
now.) There also is metal and plastic stuff IN the tank, that also is
attached to it.
Ok. The tank and the pipes and the washers expand and contract at different
rates. Then, over x number of years ,the `rubber or plastic part gets
discouraged--who wouldn't?--as do pressure cooker gaskets, garden hoses and
so on.
Well as these expansions and contractions are NOT even, after a while the
porcelain gets pissed off [!] , tired, and cracks.
There also is the factor--around here anyway--that the water that comes into
a tank that is in a 70 degree room is icy, I mean icy, cold. That is quite
a shock.
So the unloved, underappreciated, exploited tank gets tired and rebels. I
probably would crack under those circumstances too.
