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.
