    Something don't sound right I'm not qualified to answer any of your questions, I know I run my RO for a couple of minutes using a bypass valves before it goes into DI vessel got the info from davieboy and spruce sounds like your membrane could need changing,

    This is pure guess work but maybe the membrane had slight imperfections during manufacturing process causing premature breakdown like I said I'm not qualified to answer hope you get it sorted soon.

    If you have only changed the prefilters once since it was new in February then there-in probably lies your answer mark lee.
    How many liters a months do you use? What your waste to pure ratio? What carbon block prefilter are you using? What size is the filter housing?

    Once the carbon block prefilter's service life is up it no longer removes chlorine from the water. Chlorine destroys membranes.

    when i first started in February i would only fill the tank twice a month as time went on more customer more water twice a week now,
    What your waste to pure ratio ? not sure how to answer that but ionic have the flow out the side of the van 3 finger width if that helps?
    both filters changed after 6 months these are 1 x10 inch carbon block and 1 x sediment filters
    carbon block prefilters are 2 Stage Filtration HMA Home Drinking Water Filter System Replacement 10" was told these ok to use,
    i wonder if these ro have to have constant hi use?
