[C320-list] winterizing

[Chris Burti]

Jim,
I have never winterized because there are too many good sailing days
during the winter here, but in areas where they are subject to hard
freezing, water remaining can damage the tank and fittings where they
join.

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.
