1. Low tap pressure is one of the most common causes
of low flow of pure water. Source water pressure is the
primary driver of system performance. Even sources that
appear to have plenty of flow out of the tap may not have
enough PSI to push water through the RO membrane.
Ensure that the tap pressure is sufficient using a pressure
gauge (P/N TA-PG). Trying a different source may lead to
better performance. Also check all hoses (incoming and
outflowing) for kinks or blockages, especially hose reels
that are wound too tight. Trying a larger diameter hose
(½” or more) or a shorter hose length between the system
and the tap can also improve flow. Adding a pump, such
as the abc boost pump, can help compensate for low
source pressure. Do not exceed 120 PSI when using a
pump.
2. Mineral fouling of the RO membrane will lead to
reduced pure water production from your system.
Processing water through the RO membrane without
enough (or any) bypass flow will lead to increasing
mineral concentration within the RO housing. In minor
cases, this will result in a temporary drop in production
from the RO membrane. Flushing the excess minerals
from the housing will return the filter to normal production
rates. In extreme cases the mineral buildup will
permanently reduce the flow rate of the filter. These cases
can only be fixed by replacing the filter.
3. Biologic fouling is another potential cause of reduced
pure water production from the RO filter. Algae, bacteria
and fungi can land and grow on the surface of the RO
membranes. These organisms eventually block off
pores in the membrane leading to reduced production
levels. Letting filters sit for long periods of time without
running any water through them increases the chances
Do not allow the filters or system to freeze. Failure to
do so could result in damage to your filters and Phaser
system. Do not allow DI or RO filters to dry out. Dry
DI resin will lose its charge and therefore become
unable to remove dissolved solids from the water. Dry
RO membranes will develop cracks which allow more
dissolved solids to pass through the membrane. This
will deplete the downstream DI filters at a faster rate.
abc recommends that you run water through your
Carbon and RO membrane filters once every 2 weeks
or so, not only to help keep your filters moist but to
also wash out any microorganisms that might try to
grow in your filters. RO and DI filters need to stay moist
but do not need to be full of water. Always run your
source water through the Carbon filter before the RO
membrane when flushing the filter.
abc strongly recommends flushing out the RO
membrane filter once every 2-4 weeks to ensure
the maximum lifespan of the filters. When flushing
the RO membrane filter, the source water should be
passing through the Carbon/Sediment filter before
the RO membrane. This will prevent damage to the
membranes from chlorine and chloramine. Periodic
flushing will ensure that the filter membrane does not
dry out and will reduce the chance that biological
growth will foul the filter elements while in storage.
If periodic flushing is not feasible, we recommend that
users wrap filters tightly in plastic wrap or plastic bags
and then seal with tape. This will reduce the chance
that the filter dries out when in storage. Do not allow DI
or RO filters to dry out. Dry DI resin will lose its charge

1. Remove Carbon/Sediment and DI Filters.
2. Using a 7/16” wrench, remove the clamps from the
RO Membrane filter (P/N WF2CRO-40) that doubles
as the stabilization base for the unit. Retain for
future use.
3. Remove fabric handle and install onto new RO
membrane.
4. Remove bypass hose.
5. Attach handle and clamps to new RO filter.
6. Attach bypass hose to new RO Filter.
7. Attach Carbon/Sediment and DI Filters.
Do not overtighten.

and therefore become unable to remove dissolved solids

which allow more dissolved solids to pass through the

Store filters indoors over the winter. Do not allow the
filters or system to freeze. Failure to do so could result
in damage to your filters and Phaser system. After filters
have been stored this way, they will need to be flushed
thoroughly before use. Leaving filters wrapped for
extended periods of time can lead to biological fouling,
which is why we recommend periodic flushing.
