Thanks to all,
not only for the general wealth of information over the past
several years, but also for answers to some very specific
questions I've had the last couple of days. I have not
been able to add much of my own, but did just replace the
Raymarine auto helm brains with their new unit; if any
interest, I could certainly digress on it. 

The flurry of
my writing has to do with plans to take Aletes to the Caribbean
this fall. The D-50 water maker has not been used for at
least 8 years. I did change the membranes this
spring. 

I believe the
water maker hoses have never been changed, which, at a 1999
keel laying, makes them at least 15 years old. I have read
with interest the experiences with hoses going bad, and not
only leaving you potentially without water, but also
providing a great lesson in metallo-salt
chemistry. 

I would like
to pre-emptively replace the two high pressure hoses. My
interpretation is that the fittings are reusable, that
it's usually the hose-fitting interface that
fails. 

I would like
to order the correct size high pressure hose. I believe it
should be rated at least 60 bar, probably safer to err
towards 100. My problem is with the size. The Desalator
literature talks about a 10 mm inner diameter. Does anyone
have direct knowledge of this? A post from Bill on BeBe mentions a 5/16 hose,
made in Italy, which is an unusual size for a European
source (I wish the U.S. would go metric, but probably not in
my children's lifetime). Plus 5/16 is almost identical
to 8 mm. At this point, there are so many hoses, which adds
to the confusion.

Any thoughts
on hose size? Are the fittings truly reusable? Are the lower
pressure hoses OK for now if they look good?

Thanks
again,
Tom
