Looks like a lot of new systems auto flush every 5 days.....A lot of coin for water but its first on my list when ever I get rid of my pesky job and take off for months at a time....
Any comments from the watermaking guru's about drawing the raw water intake from the same through-hull as another service such as your generators cooling water intake?
This is not correct.
You need a water maker with an automatic flush cycle designed into it. I have a water maker, it gets used for 10 hours in summer and 4 hours in the winter. It’s never been picketed and works fine. I can’t recommend it as the company is no longer in business.
My neighbor has a Spectra. My neighbor is a live aboard and makes all his own water. I’ve been very impressed with the Spectra, after 12 years of making water weekly he is now replacing the membranes as preventative maintenance. He is a doctor who sometimes goes off on 4 month missions, all needs to do is make sure the tank has enough water in it for the auto flush.
I am really impressed with the Spectra water makers, you push one button to turn it on and you are done, no valves, no knobs, you can even set it up to run for a specific time and auto stop.
Spectra’s are not cheap.
Most cruising boats have a salt water washdown...
Now for one last question, and then off to another thread....
Once I have made water, I need to transfer it my fresh water tanks. This means plumbing a line into the storage tanks from the RO unit.
I could splice into the inlet tubing of the main water pump, but I assume there is usually a check valve somewhere in that line to prevent backflow into my water storage.
Correct?
Mine is plumbed right into the top of the tank. I do know someone who has a splitter that enables him to divert from tank directly to a container. My installer didn't want to do that.
I'd avoid cross-connections of potable water. Preferred way would be to drop the product output into the top of the tank, that way you've got a built-in air gap (of sorts), much more difficult to siphon back into the product line of the watermaker. If you must tee into anything, I'd use the fill, it isn't under pressure, and provides an air gap.Now for one last question, and then off to another thread....

You use over 300 gallons a day? Is your boat a charter yacht? I live full-time on a boat by myself, and without any extraordinary means I used approximately 30. To 40 gallons a week
