I just got done installing a Cruise RO watermaker (well, most of one). I spent a few weeks scrounging through threads like this one, looking for the most "bang for my buck". My relative inexperience installing DIY watermakers (I've installed a small few Pur/Katadyne units but that's it) was a problem, and I found Rich and Charlie to be helpful, even though I was basically just sourcing parts
through them - not buying
a watermaker as such. I picked up 2 membranes and a HP pump from them, basically for the cheapest prices I found anywhere online, and they provided some high pressure hoses and tech support. I was building the basic system in France
it in the UK, and connecting it to the NPT fittings from the cruiseRO people, what a headache. I'm also doing a bunch of custom stuff - setting up electronic valving to auto-flush, installing a "day tank"-type setup for saving product water, etc, and they've been helpful even when they're not making money
off of me.
What I would do differently next time: buy the prefilters and salt-water pump from the same supplier - just because it looked like I can get the same parts
locally for cheaper, I spent a bunch on adapters and the headaches wasted a ton of my time. I think I was sort of an atypical case, doing the work in 3 different countries, but maybe others can learn from my mistakes
Anyway, I overall had a really positive experience with them, and it was great to see the huge volume of product water compared to the tiny overpriced Katadyn
units. We cross the Atlantic with the new system in a week, so if I get a chance I'll post a followup.
BTW, it's a 220V electric
HP pump, which we can run from the inverter for about 6 hours (draws about 100A at 12V, thank god for LI batteries). That's over 200 gallons, which is the total tank capacity for our boat. No complaints there. We do plan to run the genset mostly when we make water, though.
