Hi, Glenn, and group,


Practically speaking, I know the broker and owner are not going to spring
for a commercial test, and I'm not going to drive down there again just for
that.

So, I'll just have to go with what I've got, and can get info on. At the
moment (still pretty early in the game of asking for input on the subject),
I have the suspicion, confirmed by several correspondents either here or on
one of several sailnet lists I subscribe to, that it's not been flushed
frequently enough. I believe that there are filters which might resolve the
Chlorine issue, but the flushing (based on what the broker told me, and it's
his word, and work, that's being relied on) is not nearly frequent enough.

All watermakers have pre-filters but the carbon filters are separate.
There may even be two. One on the product line ans part of the final
treatment and, rarer, one on the flush water supply. but as you say, it
may be to late to check.

All of my searching to date has not produced either a Power Survivor 80 for
sale in some catalog, much less a manual therefore (I was far too busy in
the survey/sea trial to remember to look in the manual, which I'm pretty
sure is on the boat), but what I have doesn't look like what's in the
40/160s I've been able to see. All the PS models I've seen have been a
single membrane, and this has two. This is also a 110 rather than 12v
installation, so I'm wondering if that's what's really there. In any event,
I'd far prefer to have some definition from the manual in order to present
on that option. It *is* one of the not-proven items (the only other being
the SSB) which the broker has agreed requires some consideration.


The main thing is, BUY A BOAT!! You have put more labor into looking
for one than I have in building one. :-)


For those waiting with bated breath, I'm going to post in more detail once I
get caught up, but right now I'm over my head in trying to get a reasoned
counter together while I wait for the written survey, and find insurance (no
luck so far, at any price), and, finally, settle on a yard where she'll go
when we leave. That date is still tentatively set for March 1, and we *do*
expect we'll get it worked out. You can see the survey pix at
www.justpickone.org/skip/gallery, and check the survey folder. The boat is
High Time, in another folder. However, the short story is that we're doing
just that. Research, investigation, offer, counter, accepted
counter-counter, surveys, sea trial have all happened. Receipt of the
report and final negotiations will happen within a week. We expect to sleep
aboard the weekend before, close first thing in the AM, turn the key and
leave.

Back to the story, I'll need something which I can use other than
scuttlebutt in order to support a demand for credit for new membranes.
Glenn, you could help with sources for me of the high-priced spread, along
with the economy reality, should it prove that way. Thanks to all - and
please let me know if you have a source for showing a picture of the actual
item (Power Survivor 80) claimed by the listing, and, even better, someplace
of an on-line manual. It may be simply that this was converted to 110, and
the rest is just difficult to see in the way it's laid out vs the pictures
of 40/160s I've seen, but in any case, I'll need something with authority to
expect it to be accepted.

Here is the Filmtec datasheet. You will see that the free chlorine
tolerance is less than .1ppm.

The PUR site does not cover watermakers but I found this site with the
entire line listed. http://www.paradise-marine.com/pur_watermakers.htm

It does not look like PUR makes either a two membrane or 120V system so
you are probably looking at something else. Which IMHO is a very good
thing. If the broker didn't know about the chlorine intolerance he may
be referring to all watermakers as "PUR" the way Klenex is used for
tissue.

One thing I did notice is that the PUR membranes are not standard sizes.
That is why they can charge twice as much for replacements.

Assuming they are standard 2.5" diameter (OD of the pressure vessle end
caps is about 3.25" and length is either 23" or 43" ) you can buy
SW30-2521 membranes for about $180 and SW30-2540s for about $290.
