I see that Yahoo did garble that link, so just search it directly. And, yes, keep the fresh water flow normal and you should be ok. I think the issue with long term pickling may be damage to the membrane rather than just needing a "cleaning", but you should be able to tell - if your TDS is low after firing it up you may have dodged the bullet.
Cheers, Craig

Craig , I will watch the video, I would really like to run it now before I leave, so that I can replace/repair here before departure. The membranes have only been used for six months , then pickled for 31/2 years . I don't know what that does to them , it seems if you ran them for awhile they would clean themselves ,who knows ,I don't. So you are saying as long as I don't turn the pressure up beyond the green zone , it would be OK .See ya in ST. Michaels.

Hi Pat,

You definitely can run your watermaker in fresh water without ruining the membrane(s). The only caveat is that you must not exceed your fresh water output rating.  

Start your unit up with, as Alan says, the pressure knob fully closed (which you normally do). Then bring the pressure up slowly and monitor the fresh water output flow. In sea water, where you might need 800 psi to get your rated output (mine is 20 gph), in brackish it's maybe 400 or so and only 200ish in fresh water.

For a good video on this by Rich Boren, who owns the CruiseRO company, check out
If the link on the last line gets garbled by yahoo, it is http colon slash slash blog dot cruiserowaterandpower dot com slash can-i-run-a-marine-water-maker-in-fresh-or-brackish-water slash

I used to do this all the time on Sangaris, so I know it works.

Alan, I am concerned about that , leaving them pickled so long and they were new four years ago. So it sounds like there is no way to fully test the system until I get to salt water. If I could find a way to make up some salt water and recirculate it ,that would work. I would like to put it through a stress test prior to heading for the Caribbean.

Hi Pat,

ATF 90 - Automatic Transmission Fluid SAE 90

You can rinse the membranes with fresh water with the pressure knob fully anti clockwise i.e. no pressure.
If you pressurise the membranes with fresh water you will ruin them - if they are not already ruined from sitting pickled for that length of time.
