RO membrane question?
Well I have had my Kent ro/di unit for about 2 year's now I guess. I recently just had to replace the DI cartride part of the unit. I replace the Prefilter and carbon every 6 months religiously.
After filling the 230 I replaced all 3 parts (prefilter,carbon, di) cartridge. The DI cartridge has allready started changing color and it's about 1/2 and inch up now. This concernes me as the origional DI cartridge lasted 2 year's before it was color changed up to the top. What's up with this? Is it time for a new membrane? Is there anyting to do to the old membrane to restore it somewhat? I have been restricting the output waste water from the membrane for the past few month's to not waste so much water. so I cut it to about 1/4 of the output and make sure I flush the membrane more often(like 2 times a week). some insight would be helpful. Thanks

almost sounds like you might have blowen a membraine, take a sample of water befor the Di and test it to see how the TDS is. you can also measure the output and see if you are making more water than it is rated for.

hmm maby you plugged it up by restricting the flow. there is a tft membrain cleaning kit on the net, that might work. I would undo it all and make sure there is no blockage anywhare first though.. and quit restricting the waist flow you can do some dammage and make bad water doing that to much.

what color is the cartrage changing to?
the company i work for as a rule of thumb on our water purifying machines is that we clean our ro membrains once a year or if the product water tds a certain level.
