I have a PUR80, but I am posing this as a more general question.
What is the life expectancy of well cared for watermaker
My first set went cruising for five years, getting used nearly daily. When I laid up the boat
for five years I accepted that new membranes would part of getting out the next time. The second time out, with new membranes, again for five years, again nearly daily use, and always great water
quality according to my TDS meter.
I've been tied to a dock
now for 2.5 years, and won't get out till this Fall. I have run, and re-pickled every six month. The TDS reading, after running for two hours, each time has shown in the the normal range.
Should I budget
for new membranes before I leave? It's nearly a boat
unit to put in new ones, and I'd sure rather continue collecting that .75% interest on those precious cruising chips.
The boat only has a 40 gallon tank, so crossing oceans requires a functional watermaker
or a radically different lifestyle than I prefer. I depart with full tanks
and top them off daily. If the trusty WM failed I would immediately go on short rations.
I've read plenty of manufacturers recommendations. What I am looking for here is real world experience. Anybody out there with regularly used membranes that have gone ten years? Twenty?
