TECHNICAL SPECIFICATIONS

CONDITIONS
READ THIS FIRST!
NOTE! Please make sure your
in󰏭allation location has enough room
for the RO Sy󰏭em and Water Storage
Tank.
(For UV Sy󰏭ems) The Ultraviolet
Sterilizer requires access to a 110V
power outlet; make sure you have safe
access to power for this sy󰏭em (not
to be shared with garbage disposal
- power surge protector highly
recommended). Do not look directly
at UV Bulb without protection!
NOTE! ACCEPTABLE WATER
SOURCES Potable community source
water or potable private well water
that is properly chlorinated to provide
proper microbiological protection. For
liability reasons RO manufacturers and
even UV Disinfection manufacturers
will not take responsibility for
giving you any microbiological
protection, and therefore leave it up
to you to be sure the water is r󰏭
properly disinfected with chlorine.
Performance will vary based on local
water conditions.
Incoming Water - Incoming water
pressure mu󰏭 be between 45 PSI
and 80 PSI. If your water pressure is
under 45 PSI you will need a boo󰏭er
pump for your sy󰏭em. If your water
pressure is above 80 PSI you will
need a pressure regulator for your
sy󰏭em. Te󰏭 your water pressure
occasionally to make sure the sy󰏭em
is performing.
Leaks - The Leak Stop Valve mu󰏭 be
in󰏭alled. Inspect all connections after
the in󰏭allation to make sure no leaks
occur, wait until after the sy󰏭em is
pressurized (turned on) to inspect
again. Check sy󰏭em occasionally after
in󰏭allation or maintenance to make
sure no leaks have developed. In󰏭all
the sy󰏭em in a location with adequate
drainage.
General - This RO Sy󰏭em unit is
for climate controlled indoor use
only. Exposure to overly high or low
temperature ranges will damage
the unit. Follow all of your 󰏭ate
and local laws and codes regarding
plumbing even if they dier from
what is 󰏭ated in this manual. If your
󰏭ate law requires it or you prefer to
we recommend using a professional
licensed in󰏭aller or plumber who
meets the requirements of this
sy󰏭em. All O-Rings, ttings, lter
cartridges, lter cani󰏭ers, and Teon
tape wear out after a certain period of
time. The lifetime of your components
are subject to change with the quality
of the water supplied. Do not handle
an unwrapped lter directly with your
bare hands as this can cause early
lter failure. Use appropriate eye and
face protection when performing any
drilling.
Sy󰏭em & tank in󰏭allation location is
recommended to be no more than
10ft away from the RO faucet and any
other P.O.U. (ie. fridge) to prevent loss
of pressure. Tubing extended more
than 10ft away from the RO tank and
faucet may not create enough back
pressure to shut sy󰏭em o.
Maintenance - The owner / user is
obligated to properly maintain the RO
Sy󰏭em when necessary, at lea󰏭 every
1 year. This includes the following:
• Replace the O-rings on the lter
housings, membrane housing, ttings,
and lter cartridges.
• Replace any connectors and lter
housings with proper replacement
parts.
• Maintain & check tank pressure at
7-10 PSI on an empty tank.
• Sanitize your sy󰏭em as often as
needed (how often changes with the
prole of your area’s incoming water).
• Always use proper replacement lter
cartridges with the correct size and
length replacements.
• Replace the Teon Tape on all
threaded connections and ttings.
NOTE! If your water is
microbiologically unsafe or of
unknown quality do not use
this sy󰎣em without adequate
disinfection before or after the
sy󰎣em. Extremely hot or cold
incoming water will damage the
sy󰎣em and cannot be used.

To Cut Tubing
Make your cuts again󰏭 a at cutting surface with a razor blade, or use a handheld tube cutter. Any cuts to your Tubing mu󰏭 be
perfectly 󰏭raight.
NOTE! Improperly cut Tubing may leak water or fail to lock into Fittings.
Wait until all elements of your RO Sy󰏭em are in their nal locations before cutting your Tubing. Make sure you measure the
length you will need before cutting in order to avoid unnecessarily lengthy tubing.
Attach Tubing
Push Tubing in 󰏭raight and level with
the Collet. The Tubing will go ⅝” into the
Collet before the lock is activated. Pull out
on the Tube to make sure the lock has
activated and the Tubing is secure.
NOTE! Once connected, make sure to
check tubing is secure.
Insert or Remove Locking Clips
To lock a Tube in place make sure the
Tubing is fully inserted then slide the open
end of the Clip between the Collet and
Fitting. The Clip mu󰏭 be removed before
the Tubing can be removed. To remove
the Clip pull away until it slides out from
between the Collet and Fitting.
NOTE! Make sure to remove any plugs
before attempting to insert tubing.
The tubing in your RO Sy󰏭em uses a Quick
Connect locking mechanism to lock the
Color Coded Tubing in place. Be careful not
to damage your tubing as you unpack it.

NOTE! If your Cold Water Valve is too old or weak to connect to directly
Option Ayou can connect at the top of the line where the faucet connects
Option B(if applicable, some sinks do not have this connection point).
1. Locate the Cold Water Valve underneath the sink and turn it o
completely. Next, open the cold water handle on your sink to release any
pressure by expelling any exi󰏭ing water. Check to make sure the water has
󰏭opped owing completely before proceeding.
Do Not Connect To Hot Water Line!
NOTE! On single-handle faucets the hot water may have to be turned o
to prevent hot water crossover (only during your r󰏭 in󰏭allation).
If water 󰏭ill continues to come out of the faucet with the Cold Water Valve
turned o, then the main water supply mu󰏭 be turned o as well.

RO FAUCET
The RO Faucet may be in󰏭alled on any
at surface. Check the underside of
your in󰏭all location for interference by
making sure that drilling a hole will not
damage any pipes or wiring underneath
the counter top or sink. Check to be
sure there is enough room for the
Threaded Faucet Stem.
NOTE! For drilling you mu󰏭 use an
appropriate drill bit and drilling method
for the material of your sink and counter
top. Dierent drill bits are required for
󰏭ainless 󰏭eel, porcelain, granite, etc.
You may use an exi󰏭ing hole in your
counter or sink or drill a new hole (if
using an exi󰏭ing hole begin at Step 2).
Make sure the Base Plate is big enough
to cover the hole you use.
Porcelain Sink
A proper porcelain ½” drill bit is 󰏭rongly
recommended to prevent chipping if
you are drilling on a porcelain sink. Drill
slowly to avoid chipping during the
initial cutting of the porcelain.
Stainless Steel Sink
1. Use a proper ½” drill bit (depending
on your sink/counter material) to make
a hole for your RO Faucet.
2. Insert the small rubber washer, then
the base plate, then the large rubber
washer (see image on next page) onto
the Threaded Faucet Stem at the base of
the RO Faucet. Then put the Threaded
Faucet Stem through the newly drilled
or preexi󰏭ing hole. Make sure the RO
Faucet sits in the center of your new or
exi󰏭ing hole.
3. Under the sink in󰏭all Pla󰏭ic Washer,
Lock Washer, and Hex Nut (see image
on next page) onto the Threaded Faucet

The Drain Saddle is used to
connect the Black Drain Line to
the drain pipe under the sink,
to allow the sy󰏭em to ush
contaminants down the drain.
The Drain Saddle is designed
to t around a 󰏭andard 1½”
OD (outer diameter) drain pipe.
The Drain Saddle should always
be in󰏭alled above (before) the
P-Trap and on a 󰏭raight vertical
or horizontal section of pipe.
To avoid clogging the drain
line with debris do not in󰏭all
the Drain Saddle after the drain
pipe meets a garbage disposal
or dishwasher drain. Refer to
the image below to see ideal
Drain Saddle locations.
Please contact us if you need
help locating a drain saddle
placement.
1. Once you have found where
your Drain Saddle will go on the
Drain Pipe make a mark for the
opening there with a marker or
pencil.
2. Use your drill and an
appropriate ¼” (6.35mm) drill
bit to drill a hole at your mark.
Be careful to drill through one
side of the pipe and 󰏭abilize
your pipes while drilling to
avoid damaging them.
3. Find the half of the Drain
Clamp with a hole in its center.
Then remove the backing from
the Foam Gasket (the foam
circle at the center of the Gasket
is disposable). Make sure to
align the Foam Gasket hole with
the Drain Clamp hole and 󰏭ick
the adhesive side of the Gasket
to the inner wall of the Drain
Clamp half.
4. Take the half of the Drain
Clamp without the Foam Gasket
and insert a nut into the recess
on each side.
5. Position both halves of
the Drain Clamp on the drain
pipe with the clamp’s opening
aligned over the drilled hole.
The Foam Gasket will be
between the drain clamp and
the drilled hole. Push your ¼”
drill bit through both holes (the
Drain Clamp hole and the hole
in the Drain Pipe) and remove
to verify that the clamp is
properly aligned with the hole
you drilled.
6. Secure the Drain Clamp
halves together in place on
the Drain Pipe. Screw the bolts
through the Drain Clamp half
with the Foam Gasket and into
the half you in󰏭alled the nuts
into (Do not over tighten. Make
sure there is equal space on
both sides between the Drain
Clamp halves).
NOTE! Please make sure drain
line is free owing, and ow
is not re󰎣ricted in any way.

AUTOMATIC SHUTOFF VALVE
Also known as the brain of the sy󰏭em, the Automatic Shuto Valve
reads the back pressure from the RO Tank once it’s full, and shuts
the sy󰏭em o automatically to 󰏭op draining. As the RO Tank water
󰏭orage depletes, the Automatic Shuto Valve will open and initiate
the sy󰏭em to 󰏭art purifying the water, ensuring that you have RO
water readily available.
The Automatic Shuto Valve activates when back pressure builds
up in the product line due to a full, pressurized bladder tank.
To conserve water, the back pressure from the full tank will be
detected by the Automatic Shuto Valve and shut o the incoming
water to the RO Membrane.

Prepare Prelters
Leave the lters wrapped until
you need them. When in󰏭alling
be careful not to touch the lter
portion with your hands.
Remove the pla󰏭ic wrap from the
3 Filter Housings and 󰏭and them
upright. Make sure each Housing
has two O-Rings rmly in place at
the top of the Housing and in the
Housing’s lower groove.
Food grade lubricant pre-applied
on O-rings. Please do not wipe o
to prevent over-tightening.
NOTE! Reference image to

in the Housing in the
correct direction you noted
earlier. Make sure to push
the Membrane in rmly,
then close the Housing by
tightening the cap with your
hand, and use Wrench to seal
securely.
If this is the only / la󰏭 lter
you are replacing continue
to the Re󰏭arting the Sy󰏭em
section (page 19).
1. You will need a clean cloth, dish soap,
lter housing wrench and appropriate
SED, GAC, & ACB lters.
(We also recommend a bucket or bin
large enough for the sy󰏭em to sit
in - water will be released when it is
disassembled.)
2. Turn o the Cold Water Supply
connected to the RO Sy󰎣em and the
Feed Water Adapter Valve (page 9).
Then open the RO Faucet handle to
release pressure, and empty tank.
Close handle when the ow of water
󰎣ops, then close tank (page 15) (for
UV sy󰎣ems, unplug the power cord

3. Place the RO Sy󰏭em in the bucket and
unscrew the 3 Prelter Housings using
the Filter Housing Wrench. Remove old
lters and dispose of them.
4. Wash the Prelter Housings with dish
soap then proceed to rinse until all soap
is removed.
5. Ensure that your hands are washed
clean before unwrapping the new lters.
After unwrapping, place the new lters
inside their correct housings (page 13).
Make sure the O-Rings are in their proper
locations.
6. Tighten the Prelter Housings using

Make sure the O-Ring
is in place before
you tighten
the Membrane
Housing Cap.
NOTE! If you are having less than the
normal 0.8 gallons a minute ow from
the RO Faucet, it may be due to the
Tank Air Pressure or the incoming water
pressure being too low. If you have an
incoming water pressure of 50-80 PSI, we
ask that you check the pressure inside the
tank to verify that there is 󰎤ill between
8-10 PSI of air in the tank WHEN THE
TANK IS EMPTY.
Please lift the RO Tank and let us know
if it produced a full tank of water or no
water at all. If so, please check the tank
pressure. We recommend emptying the
water from the Tank. Once empty, please
add up to 10 PSI max into the Tank. This
should help increase the water pressure
coming out of the Tank. Do not add any
more than 10 PSI or you will not have
any room for water 󰎤orage as it will be
mo󰎤ly air pressure.
You may check the air inside the tank
using the air valve in the bottom of the
tank and a regular pressure gauge (as
you would with car tires).

20
Does this sy󰎣em lter Fluoride, Lead,
Pharmaceuticals, and Arsenic?
Yes, as well as Cyanide, Phosphate, Pe󰏭icides,
Sodium, Cadmium, Sulfates, and many other
contaminants up to certain levels. Depending
on incoming water quality, you may need
pretreatment for high levels of certain
contaminants.
What PSI do I need? What is the operating
pressure?
The minimum PSI for the sy󰏭em is 45 and
the maximum PSI is 80. If your PSI is too low
you can purchase a Boo󰏭er Pumps to aid
your sy󰏭em. If your PSI is too high you can
purchase a Pressure Regulator to reduce your
pressure to acceptable levels. Let us walk you
through these options.
Does it 󰎣op lling automatically when
lled? Why is the drain line con󰎣antly
owing?
The RO Sy󰏭em does 󰏭op lling automatically
when tank is lled (2-3 hours). If your drain
line is con󰏭antly owing this is a sign that
your incoming water pressure is too low, or if
lters need replacing.
Can I in󰎣all this sy󰎣em in the basement?
If so, will it aect the eciency of the RO
Sy󰎣em?
Yes, the RO Sy󰏭em can be in󰏭alled in a
basement. However, if you do not have
adequate water pressure you may need to
purchase a Demand Delivery Pump. Contact
Express Water and we’ll help you nd your
solution.
What is the discharge rate?
The typical discharge range is one to three
gallons for every one gallon produced. Your
water pressure, incoming water quality,
and water temperature will aect your RO
Sy󰏭em’s discharge rate.
Why does it take so long to ll up the
tank?
The purication process takes some time on
its own. However, some water takes longer to
process. Your water pressure, incoming water
quality, and water temperature will all aect
how quickly your RO Sy󰏭em lls the Water
Storage Tank.
How often do I change Filters? Is there an
indicator?
The Sediment, Granular Activated Carbon,
Activated Carbon Block, Deionization and
Alkaline Filters should be changed every 6
months. The RO Membrane and Inline Po󰏭
Activated Carbon Filter should be changed
every 12 months at the same time as the
second change of the 6 month lters. The
UV Bulb of the Ultraviolet Sterilizer should
be changed every 6-12 months. If the UV
bulb needs to be changed early it will alert
you with either a red light or beeping noise
from the black box (electric balla󰏭 on the
power cord). There is no direct indicator for
lter changes. However, if you notice a drop
in water quality before the 6 or 12 month
mark this may mean that due to your water
quality you lter has degraded. If you reach
6 or 12 months without noticing a change in
ta󰏭e you should 󰏭ill change your lter at this
point, as they are no longer viable.
What is the dierence between GAC and
ACB carbon lters?
GAC and ACB lters are both made with
100% Organic Coconut Shell Carbon, the only
dierence is the formation of each lter. ACB
Block lters are much more tightly packed,
while the GAC is granular loose carbon. The
compact nature of the ACB means that even
the smalle󰏭 particles and contaminants
cannot pass through the lter and placed as
the Po󰏭 lter on the bottom
Will the Coconut Shell Carbon Filter
trigger a coconut allergy?
Depending on the severity of the allergy, the
carbon lter may trigger an allergic reaction.
Can I add additional lters to my current
sy󰎣em?
Yes, each sy󰏭em is fully upgradeable. Check
the Upgrades and Accessories section
on page 22 or on our website for more
information.
Can I connect this sy󰎣em to a refrigerator
or ice maker?
Yes, you may need an Express Water
Refrigerator Kit to do so. In some cases, your
situation may require a separate tank or
Delivery Pump depending on how far away
your refrigerator is from the sy󰏭em. Contact
Express Water and we’ll help you nd your
solution.
How do I get clear ice?
Lower freezer intensity slightly to allow water
to freeze slower and allow trapped air to
escape during freezing.
Can I reuse discharge water?
Never consume discharge water. With
proper in󰏭allation it is possible to utilize your
discharge water. Contact Express Water to
speak with a qualied representative who can
give you more information based on your
situation.
How long does the sy󰎣em la󰎣? How long
does the tank la󰎣?
With proper maintenance and average water
quality an RO Sy󰏭em should la󰏭 5-10 years.
The water 󰏭orage tank usually la󰏭s 3-5 years
before we recommend replacing it.
Can I change my 50 GPD (Gallons Per Day)
sy󰎣em to 100 GDP? If so, how?
Yes, to do so, you will need dierent parts
(such as the RO Membrane and Flow
Re󰏭rictor). Contact Express Water and we will
help you arrange your upgrade.
Why are there bubbles in the water?
(NOTE - For Alkaline Sy󰏭ems it is normal to
have more bubbles in your water because of
the higher oxygen content.)
Bubbles in your water is a common issue,
but they only aect the appearance of your
water and pose no risk. There can frequently
be air trapped inside any plumbing sy󰏭em,
so the air may be coming from your home’s
plumbing and not the RO Sy󰏭em. Trapped
air happens frequently when you change a
lter, when there is a leak in your sy󰏭em or
plumbing, uctuation in pressure, or even
when there is con󰏭ruction in your area.
Check your sy󰏭em carefully for any leaks
or unexplained moi󰏭ure. You may need to
carefully tilt the sy󰏭em various directions
then set it back in place to help release
trapped air.
Does this produce aquarium safe water?
RO Deionization Sy󰏭em - The Deionized
water is safe for appropriate aquatic life. Be
sure to te󰏭 your water regularly to make sure
it is safe for your aquarium.
All other sy󰏭ems - We sugge󰏭 in󰏭alling our
Deionization Filter Upgrade to create water
for aquatic life.
Why do I need to ush the sy󰎣em?
The ushing process helps activate lters and
open pores for ecient ltration. In addition,
new lters (or lters that have experienced
extended disuse) can develop carbon residue.
We recommend emptying the Water Storage
Tank four times (which can take 8-12 hours)
to release any extra carbon before the water
is safe to drink.
How much water can the 󰎣andard Water
Storage Tank hold?
The maximum capacity of the tank is 3.2
gallons. However, the typical tank reaches
2-2.5 gallons. Your Water Storage Tank’s
capacity depends on your incoming water
pressure. Lower water pressure means the
tank will hold less water.
What should I do in a boil water advisory?
As long as all of your lters are working
properly you can drink water from your RO
sy󰏭em without boiling. You MUST replace all
of your lters after the order is lifted. While
the sy󰏭em will lter large amounts of harmful
agents, it can damage your lters and
cause bacteria to grow. You should follow
sanitization in󰏭ructions when replacing the
lters.
Does this sy󰎣em soften water?
Your RO Sy󰏭em will soften water. However,
hard water does reduce the lifespan of your
Filters.
What if I need to produce more water?
There are a lot of solutions to this problem;
it’s possible to upgrade your drinking water
sy󰏭em with some specialty equipment, or
we can help you with other solutions. Ju󰏭
contact us and we can help you nd the
solution that be󰏭 ts your home.
