This broker doesn't know what he is doing or what he is talking about.. And
just looking at the discharge over the side doesn't prove anything..

All RO membranes are will be damaged by chlorine and if the system isn't
used regularly (once ever couple weeks) then it should have been layed up
with a pickling flush with Sodium Metabisufite solution or what ever the mfg
recommends..

If you serious about the purchase of this boat, then make your offer
contingent on a operational test of the unit by a "Qualified" person.. If
you in a major cruising port, you should be able to get someone from a RO
dealer/shop to come and check it out. Probably cost a few hundred buck
though. The surveyor isn't going to be able to tell you anything for sure.

BTW, those RO membranes aint cheap.. If you don't want to spend the money on
a technician to test the unit, then buy the boat, but subtract the estimated
cost of a pair of replacement mebranes..
