Title: Membranes
Post by: ftp on March 19, 2009, 08:31:01 pm
When do you replace them? Mine are two years old and used to get tds of 6 now producing tds of 16. Is it time to change?

Just for reference. How to tube up the membranes.
Looking from left to right, The left with the screw top and in feed.  The right side the lower is waste and upper is pure? Is this correct?
