I have been using unit for last two days using a reliable tester. Have checked it using RO and bottled water with good readings. Readings for last two days have been running between 1130ppm and 1450ppm regardless of how long I have been running it. Water is quite salty to taste. I have never heard of a 2 month old membrane that has been consistently used in good clean salt water
failing overnight. Faulty seals seems logical to me. What doesn't make sense is that it worked flawlessly, and then Bingo!, bad water. I was able to contact Village Marine in Ft Lauderdale and they suggested I send them my membrane so they can check it out. If found to be defective they would then send me a new one. Piece of cake, if I was in the States and could overnight it to them. They could then determine the problem, and, if found defective, overnight me a new one. Things unfortunately don't work like that in the southern Bahamas
. I was hoping someone had experienced the exact problem, and could provide me with a quick fix. At this point I have resigned myself to hauling water, (like I always have previous to this year)and taking care of it upon returning to the States in May. Oh well, it was fun while it lasted. Thanks for all the suggestions.
