Default Watermakers and Chlorine

Take off $700 from the purchase price for the replacement of the
membranes. The broker may have prevented bacterial growth but he has
ruined the membranes. They are long gone. Chlorinated water is death
to RO membranes.

If they are standard 21"x2.5" membranes you can get Filmtec SW30-2520
membranes for about $200 each but don't tell the broker that. Have him
call Pur and get their ridiculous price. :-)

I'm about to buy a boat with a Power Survivor 80 watermaker, installed in
2002. The owner died about 9 or so months ago, and there's some question as
to whether he ever used it.

I think I recall hearing that Chlorine was damaging to membranes. There are
two, about 2' long, on this model.

The broker has been flushing this system (not ever making water in the 8+
months it's been in a canal berth in Ft. Lauderdale) with city water every
few weeks, and assures me that this is proper for this model, claiming that
flushing as he does is adequate and frequent enough. Looking at the output
(overboard), it starts cloudy and goes clear.

So, is the first assertion (Chlorine is trouble) correct, and if not, does
the second assertion (this model doesn't require pickling), combined with
approximately 3-4 weeks between flushes, hold water, pardon the expression?

If there's trouble brewing, I'd greatly appreciate a link to support it, as
it's one of the items on the survey, and we're supposed to counter in a few
days...

Thanks, ever so much...
