[C320-list] winterizing

[Allan S Field]

I remember Gerry Douglas from Catalina making a statement several years ago
that almost all hot water heater failures are due to poor winterizing - not
getting all the water out.  My own experience is that even with a large shop
vac, I don't get all the water out.  I need the air compressor to get the
last of the water out.

In thinking about winterizing this year I began to wonder why it's necessary
to drain the water heater bone dry to prevent freezing damage. If the drain
is open and there is a small amount of water left, when it freezes wouldn't
it just expand by going up and cause no pressure damage on the sides or
bottom? Same for the water tanks?  I always vacuum out the hot water tank
and make sure the water tanks are dry but wonder if it's necessary.
