That's 90 gal/month, give or take, I'd say it's time for the DI to be change along with the membrane, then eveything is fairly new(including the other cartridges).
The membranes, once hydrated, cannot be allowed to dry out. When a membrane dries, it is no
longer able to purify the water and would need to be replaced. When the unit is not operating,
the membrane housing MUST stay wet. If the unit is portable and makes water once or so a
month, store the unit with the tubing above the membrane housing to prevent draining. If the
unit is not going to produce water for over 4 weeks, the membrane needs to be removed from
the membrane housing and stored in a plastic, air tight bag with 2 tablespoons of product water
and placed in the refrigerator. Doing this will prolong the membrane life. let the
membrane freeze. Regular maintenance of the R/O unit consists of keeping track of about how
much water the unit is producing. This can be estimated.
The following chart is the
recommended change times for all the filters.
1 canister- 1 micron string wound filter:
Change every 6 months or earlier if filtering heavy sediment, looks
dirty or unit loses flow.
2 canister- -solid block carbon matrix filter: Change
every 3,750 gallons of water production (waste + product) at 2
ppm chlorine, or every 6 months.
3 canister- - or :
post deionization resin cartridge or Hi-S™
High Silica removal resin: These resins are color indicated,
exhaustion starts from bottom up. Once color change is one inch
from the top, the cartridge needs replacing.
Membrane- rated gpd)-Thin Film Composite, , ,
:
Under average conditions this membrane can filter
25,000 gallons or around 3 to 5 years of service. The
existence of fouling chemicals in the tap water like Iron,
Calcium, or Magnesium, will reduce the membrane
life exponentially. Kent Marine makes an add-on called
the flush kit. Adding this kit will greatly decrease
the chances of the fouling chemicals from destroying
the membrane.
Too much product water, little waste or resin exhausts quickly: Cause: the membrane is not
fully seated in the housing. See diagram 1 & 2 from opposite side of these instructions.
Not enough product water, lots of waste: Cause: Check the TDS, Temperature, PSI as stated in
the Overview section. Make sure you have given the membrane enough time to completely
hydrate. If all the common problems have been ruled out, contact Kent Marine 's Technical
Department for further assistance.

Most phosphate and nitrate test kits cannot read R/O, Deionized water
properly. If testing for these, they will give a positive reading.
