Re: Excessive usage of water maker membranes
toggle quoted messageShow quoted text
We had the 100L/Hr Duo on Island Pearl II and went around the work in three years with a new 2016 set of membranes. Those membranes were still perfect at the end of our trip doing a full 100L/Hr easily on the a/c current but slightly down to 75L/hr on the DC current motor.
We were absolutely fussy about the cleanliness of ocean water before running it and were sometimes scoffed at by others eg in Rodrigues (Indian Ocean) for lifting anchor, risking losing our good spot to go out to sea every four-five days to make water whilst other cruiser friends simply made water inside the large seawater harbour where we felt the water was not up to scratch. Also, we never took the boat out onto the hard for a season, even though we had planned to do this in the Caribbean in 2019.
If you are careful like this, which I suspect you are, then there must be something else at play with your system and I look forward to hearing about that from other more experienced cruisers here.
Also, since we have communicated often and I admire your equally careful approach to looking after Creampuff, I highly suspect that when you refer to "running your watermaker at least once per week in marina's", that you actually meant "doing a freshwater flush cycle" in the marina from your tank as per the manual requirements.... rather than actually making water from the extremely dirty marina seawater which would totally explain everything about your problems, but which I am equally sure you would never have done.
