LEAk PREVENTION PAgE
ATTENTION:
Before commencing any work on your system you need to depressurize your system - see Figure 29. To
repressurize your system when you are done, turn the tank top valve and the manual shut off valve back on.
Threaded Fittings
To prevent a leak on any threaded fitting that screws into the Reverse
Osmosis System you simply need to employ Teflon tape. The main
instructions pages indicates the preventative measure of wrapping the
threads of the various threaded fittings 4-7 times with Teflon tape.
This preventative measure will ensure against any potential leaks from
the various threaded fittings throughout your Reverse Osmosis System.
ADDING SUFFICIENT TEFLON TAPE IS KEY!
If you are experiencing a leak from a 1/4 inch tube inserted into a quick connect fitting, you simply need to insert the
tubing into the threaded fitting further. To do this you may need a small pair of pliers to assist you in gripping the tube.
If the use of pliers is needed, grab the tubing 3/4 inch from where the tube inserts into the threaded fitting in order to
not scratch the section of tube that will be inserting further into the threaded fitting. A scratched section of tubing
that is inserted into a threaded fitting can act as a path for water to flow, which in turn may result in a small leak.
Pre-Filter Canister Housing
All Aquasafe Reverse Osmosis Pre-Filter Housings are “Compres-
sion Sealed”. This means that 99% of the time any leak coming
from the threads of the Pre-Filter Housing can be easily fixed by
tightening with the system’s “large Canister Wrench”. A “Large
Canister Wrench” came with the Original Purchase of your Re-
verse Osmosis System
D.I. Resin Canister
Sometimes the DI resin beads can get caught up in the threads of the
canister and in threads of the DI Canister cap. Brush away all of the DI
resin beads from the DI Canister housing and rinse out the cap. Once
the threads of the DI Resin Canister are free of all DI resin beads a leak
coming from the DI Canister can be fixed by tightening the lid as much
as possible. Get a cloth to help give the grip needed for tightening
purposes. In the extremely rare case that you are still having trouble with
one end of the DI Resin Canister, you can apply a small amount of silicone (the non-hardening variety). The key to this
method is using a SMALL amount. Do not silicone both ends as you will need to change the resin beads in the future.
(Repeat the clearing of the threads a second time before you resort to this though!)

To more easily insert the tubing into the various quick connect fittings of
your system it is helpful to remove the blue “C” clip from around the collet
and then insert the tubing. After the tubing has been inserted firmly into
place, pull lightly on the tubing in order to make room for the blue “C” clip
and then place the blue “C” clip back into its original position. The blue “C”
clip holds the collet in its proper position while the system is in operation.

AquARIuM II DuAL SYSTEM FILTER CHANgE SCHEDuLE
Pre & Post filters: Defined as the filter stages Pre (before RO Membrane ) and Post (after RO Membrane).
Stage 1,2 & 3 Pre-Filters – When to conduct a filter change.
Stages 1, 2 and 3 are your system’s pre-filters which need to be changed every 1000 gallons of purified
water produced. The average household consumes 3-5 gallons of drinking and cooking water daily. At
5 gallons per day consumption rate a filter change is needed every 6 months or sooner. With the extra
water required for aquarium water changes you need to adjust this accordingly. Your aquarium’s water
changes will most likely be a consistent volume of water. Measure the approximate gallon amount
for your average aquarium water change and add that to your household consumption (drinking and
cooking water) in gallons per day. Divide the resulting number into the 1000 gallon pre-filter capac-
ity and the result will be the number of days you can go before the filters will need changing. Always
err on the side of caution and change your prefilters at least a couple of weeks early to ensure that the
water quality for your aquatic pets stays at an optimal level. Mark your calendar with this date!
Please Note: Maintaining the pre-filters of your system is key to ensuring system integrity in both wa-
ter quality achieved and overall longevity of its parts and components. The pre-filters are your system’s
first line of defence - protecting and ensuring the maximum lifespan of the R.O. Membrane. If you
have a PSI Meter (included with the combo system) you can also use it to determine when to change
your pre-filters (see option 2, page17).
Example:
100 gallon aquarium with 30% water change every week + average household con-
sumption of 5 gallons per day for drinking and cooking:
33 gallons per week aquarium water + (5 gallons per day x 7 days a week)= 68 gallons per week
So to calculate how long your filters would last:
1000 gallon pre-filter capacity ÷ 68 gallons per week = 14.7 weeks
So, in this example, your filters will last about 3.5 months. We would suggest, based on this exam-
ple, changing the filters every 3 months to ensure that the water quality for you and your aquatic
pets stays at an optimal level. Mark on your calendar when to do the filter changes so that you
don’t forget and make sure you have spare filters on hand.
IF THE PRE-FILTERS ARE NOT CHANGED BEFORE 1000 GALLONS OF PURIFIED WATER IS
CONSUMED FROM THE SYSTEM, CHLORINE WILL BYPASS THE PRE-FILTERS REACHING AND
CHEMICALLY DAMAGING THE R.O. MEMBRANE RENDERING IT USELESS. It is important to
understand that even if chlorine is not present, after the 1000 gallon mark, seepage may occur
where very fine particulates will bypass the pre-filters stressing the R.O. Membrane greatly. This
will result in pre-mature fouling of the R.O. Membrane resulting in the R.O. Membrane needing to
be replaced before its due time – a costly mistake.
TIP
WARNING
If you are a 1 person household or a large family household it may be advantageous to monitor
approximately how many gallons of drinking and cooking water is consumed daily to factor the
proper filter change schedule for your individual situation.
• Example:
Large household or office environment consuming 8 GPD (gallons per day) with an
aqarium consuming 5 GPD is a total daily consumption of 13 GPD
1000 gallon pre-filter capacity ÷ (13 GPD x 30.5 average days a month) = pre-filter change ap-
prox. every 2.5 months.
