Steady, B. I have no affiliation with any manufacturer and I am not pushing products; are you? I did a quick search on Amazon for a generic prefab RO unit as an example from that market segment of the RO industry. I am simply a guy who hopes to one day buy a boat. I am also a guy who likes to take a shower every night. And I'm a guy who has showered in enough campground showers to know I'd rather shower in my own than in a public one.
I have read here on many threads that among the benefits cruisers look forward to during marina stays are long hot showers. An expensive watermaker doesn't seem economically practical for coastal cruising (Florida being the subject here), but a system priced more in line with the application may be worth the effort, at least to me. Simple as that.
Well, you started with "So I'm in the water business and the notion of expensive reverse osmosis systems was replaced by inexpensive systems a decade or more ago." That led to a connection. Then you kept pushing a product which by it's own information is not designed and will not work for "watermaker" use on a boat, especially in salt water. Yes a cheaper application is good, but not the one you linked. It's just really a cheap water purifier, to take city water and make it more pure. That's not what a watermaker does.
