Due to bacterial growth you will have to operate the watermaker every
3-4 days. That's the only disadvantage of such a system (my 2cts worth
experience till now)....

If back-flushed thoroughly with fresh water you can run them much less
frequently than that.

That sounds interesting to me.
What is your experience?
What do you mean by "less frequently"? every 8 days?
and what by "thoroughly"? 20 minutes? HP-pump on or off?
How long have you been doing this?
Tnx, Len.


HRO sells, as an extra, a fresh water flush unit that has a timer and
runs after each use and every week if the watermaker is not used. Not
cheap, but mine has very rugged commercial-duty components. You'd have
a hard time fitting it into a small boat.

We've got a Spectra 8 gph 12 volt unit that we installed in 2000.
We've used it quite a lot since then, mostly in the tropical Pacific.
We always back-flush it at the end of each run until the pressure
drops to about 20 psi or so with the HP pump on. It takes a few
minutes. After that we just turn it off. When we are in a marina we
try to flush the unit every couple of weeks, though occasionally we've
left it for longer.

needs are for drinking.

This looks very cool; especially for a boat with a very small engine space
like mine. I wonder if some of the ideas like the simple S.S. filter could
be adapted to inboard units.

Prospective customers might want to read the SSCA forum on the company
selling the 'waterlog'.
