Dispenser/Faucet Q & A - Reverse Osmosis

Spout pulls out from faucet body that’s why it swivels. Spout has 2 o-rings at base and is inserted completely

into bottom of body to prevent leaking. Handle and tip can also be removed

Q: I do not want to drill any extra holes or use a separate dispenser/faucet - what can I do?
A: Nothing. Reverse osmosis systems are limited to a separate dispenser.

WARNING: These systems manufacture a limited amount of water and therefore the connection to the

cold side of your sink faucet is an unavailable option. In addition, the water produced by a
reverse osmosis system is aggressive and would have adverse leaching effects on any
other metals (ie: brass, copper) other than stainless steel.

Note: Drinking water filtration systems are pass through systems and will allow this option. There

will be a diminishment in your flow rate to the cold side of the faucet (kitchen faucet has a
flow rate of up to 2.3 gallons per minute and the filtered water is delivered up to 1 gallon per
minute). To get filtered water you must be sure you have the faucet to the cold side only.
This application or option is not applicable for reverse osmosis systems.

Q: I would like to use another dispenser/faucet?
A: Based on many styles and finishes, a consumer may have another dispenser they would like to use.

No problem, all these items have universal or industry standard fittings, or if not, can be easily adapted to fit.
Always check with manufacturer for proper specifications.

Note: EWS, Inc. includes a standard chrome, long-reach, lead-free faucet with white tip, handle and

optional air gap adaptor . Be aware - an air gap may be code and required with a dispenser/
faucet installation.

Options: EWS provides the following options to match other items at an additional charge;

Change your white tip and handle to black
Change your white air gap adaptor to black
Change your faucet to the following finshes; white faucet (with white tip, handle and air gap),
satin nickel, polished nickel, polished brass, or oil rubbed bronze (all with black tip, handle and
air gap). Inquire with your local EWS, Inc. distributor, cont act an authorized internet distributor
or visit us on the web (see page 4.2-25 for more details).

Q: Can we connect the filtered water up to other devices?
A: Yes, simply connect by a “T” connection, the filtered water line to any instant hot, chiller, ice-maker,

refrigerator, etc. Regarding flow rate, be mindful of too many (3 or more) connections. Also, any length of total
tubing in excess of 20 feet combined to tank, faucet, and all items may create issues with delivery rates**.
See our Point of Entry , Whole Home Appliances to filter all the fixtures within the home.

WARNING: Reverse osmosis may have warranty or restrictions with other devices, consult with other

manufacturer’s product information.

Note: **Tubing in excess of 20 feet is calculated by adding the length of tube from unit to tank

(yellow tubing) and the faucet outlet on unit to dispenser or other device (blue tubing). EWS,
Inc. supplies 5 feet of each type of tubing.

Q: Do I need to use the air gap adaptor?
A: Y es, if local code requires that an air gap be used. Since the unit is both connected to a pot able water

supply and a drain, some code requires an air gap to prevent cross-contamination, similar to all
EWS point of entry systems, a dishwaher and/or washer machines. Care has to be taken with this
unit to make all the proper connections. Follow all local plumbing codes.

Placement or Locating Dispenser/Faucet - Reverse Osmosis

Step by step instructions to mount and secure the supplied dispenser/faucet

Professional Installation is Strongly Recommended

Step 1: Locate Faucet Parts Bag

Parts Included: faucet body with handle, faucet spout with tip, decorative washer, black rubber

washer, white beveled washer, lock washer, hex nut, 1/4” tube insert sleeve,
1/4” plastic compression ferrule, 1/4” compression nut

Included flat white washer (for use under decorative washer depending on hole/application)
Optional Parts: air gap adaptor (white) for use with RO air gap applications

Preferred - Select a standard sink location to mount the faucet.

It is recommended that the faucet be placed in a hole provided on most sinks similar to the ones used for a
sprayer, soap dispenser and/or dishwasher air gap. If the hole or sp ace is unavailable, an alternative location
will be required: NON-AIR GAP: MINIMUM HOLE REQUIRED 1/2”, MAXIMUM 1 3/8”

AIR GAP: MINIMUM HOLE REQUIRED 1 1/4”, MAXIMUM 1 3/8”

Option A: On the sink. This option is to drill a new hole into the sink rim itself, if space allows.
Option B: On the countertop next to a sink. This option is to position the faucet spout in the

correct location to drain into the sink. This requires a clearance around the faucet
both above and below the countertop. Use the supplied dispenser as a template or
see the enclosed dispenser schematic and dispenser dimensions.

Prepare to drill the hole using the dispenser as a template.

• Sinks can be made of, but not limited to, stainless steel, copper, porcelain/steel, enamel/cast iron,
man-made surfaces, stone, concrete, and/or materials known or unknown at this time.

• Countertops can be made of, but not limited to, or be a combination of, natural stone, enamel,
porcelain, concrete, wood, metals and/or man-made materials known or unknown at this time.

CAUTION: Please consult with the sink or countertop manufacture, supplier, fabricator, or

installer for proper drilling techniques and methods.

EXTREME CARE MUST BE T AKEN IN DRILLING THE HOLE FOR ANY SURF ACE. THE SURFACE MA TE­RIALS OF SINKS AND COUNTERTOPS CAN CHIP OR CRACK. THE MANUFACTURER ASSUMES NO
RESPONSIBILITY FOR ANY DAMAGE RESUL TING FROM THIS INST ALLA TION.

Basic Inlet Supply Water Connection **

Professional Installation Using a Preferred Connection is Strongly Recommended

**This unit is supplied with a saddle tapping valve and should be considered a basic connection for copper , steel or brass

3/8” to 1/2” O.D. pipe prior to the angle stop shut-off of the cold water line to the kitchen faucet. This should be considered

a “do-it-yourself” connection which is not applicable in many situations and may not meet local codes.

A qualified plumber should choose to make the inlet supply water connection by a more preferred method.

Instructions from the bag containing the supplied saddle tapping valve, if applicable

Step 1: From parts bag locate: saddle tapping valve and 4’ of 1/4” tubing, color coded: red or orange (supply line to unit).

Step 4: Loosely assemble saddle tapping valve on pipe
A: For all 3/8 O.D. pipe, use side of bracket with side projections

toward or against pipe to prevent distortion of tubing.
B: For all 1/2 O.D. pipe, use “V” side of bracket with that notch
toward or against pipe.

Step 5: T ighten screws evenly . Make sure brackets are parallel,

then tighten firmly until the valve is not moving on the pipe.

CAUTION: Do not over tighten fittings.

Step 6: Connect the 1/4” plastic tubing to the saddle tapping

valve by following these instructions:
A: Slide 1/4” compression nut over plastic tubing with threads toward the
saddle tapping valve.
B: Slide 1/4” plastic ferrule over plastic tubing with long tapered side
toward saddle tapping valve.
C: Place 1/4” brass insert sleeve into the end of the 1/4” orange/red
plastic tubing.
D: Insert orange/red tubing into saddle tapping valve. Leave other end
available for system interconnection

E: Tighten compression nut onto saddle tapping valve.

Step 7: Be sure the packing nut is tight, then turn the handle of the saddle tapping valve clockwise

until it is firmly seated. NOTE: For Copper Pipe - the pipe is now pierced.

HINT: Back the end of the piercing lance out, turning the handle counter-clockwise. Then re-insert by turning the handle

of the saddle tapping valve clockwise until it is again firmly seated. This will clear any possible debris that can
block piercing lance and water flow.

Step 8: Turn the handle counter-clockwise to open the valve for water supply . Keep main line shut of f and proceed with
the remainder of the installation and start-up.

Step 2: Locate cold water line that feeds your existing faucet. Determine if there is enough
space to install the saddle tapping valve on the hard line between the wall and the angle
stop.
CAUTION: USE ONL Y COLD WATER LINE. NOT INTENDED FOR SUPPLY BY HOT
WATER.

Step 3: Shut off the main water supply to the house and open the faucet to relieve water
pressure in the hard pipe. NOTE: Shutting the angle stop only , still leaves water in that pipe.
Shut the main supply .
CAUTION: Do not turn valve handle before or while installing the “saddle tapping valve”.
Make sure the piercing lance does not protrude beyond the rubber gasket. Failure to do this
may result in damage to the piercing needle.

NOTE: For Copper Pipe - go directly to #4.

For Steel or Brass Pipe - follow A, B, C below, then go to #4

A: Drill a 3/16” hole in pipe. Use a hand drill to avoid shock hazard.
B: Turn handle to expose lance beyond the rubber gasket no more than 3/16”.
C: Place body of valve over hole so the lance fits into the hole

CAUTION:

Do not over
tighten fittings.

Preferred Inlet Supply Water Connection - All Applications

Professional Installation Using a Preferred Connection is Strongly Recommended

A qualified plumber should choose to connect the inlet supply water supply by a more preferred connection. ***

The Preferred Inlet Supply Water Connection is Applicable in All Applications and Codes

Replace the Angle Stop with a Proper 3-Way Fitting:

There are a number of options to properly install any one of these drinking water filtration systems.

Identify the cold water supply line and then you will need to know;

• Size or O.D. diameter of pipe or tubing

• Pipe material (hard or sof t copper, steel, brass, stainless, PVC, plastic, etc...)

• The existing angle stop or fitting will assist in determining the proper 3-way angle stop or fitting needed for

your specific application

4.2-9

A more preferred method to connect the inlet supply line is to shut off
the water main and replace the entire angle stop. This will have a con­nection from the house main water line, a connection to the cold water
side to the kitchen sink faucet and a much better connection for the
inlet supply to the filtration unit. This will provide one fitting with a shut
off to the kitchen faucet and a shut off to the filtration system. The
replacement of the angle stop is a better plumbing connection and any
number of fittings can be used for the correct application under any
circumstances.

Examples of common connections and fittings available:

• OPTIONS:
1/2” IPS x 3/8” compression x 1/4” compression
3-way angle stop

• OPTIONS:
1/2” compression x 3/8” compression x 1/4” compression
3-way angle stop

Note:
Be sure one outlet is 1/4” compression

Proper installation is dependent on your specific application and the concept of proper installation is universal.

Locate the supply , shut off your main water supply , install the proper connections

and follow the remaining instructions in this manual.

***EWS, Inc. can not anticipate all the different locations, applications and materials used by your builder and/
or plumbing contractor regarding your household or sink piping, therefore we offer a generic and common fitting
with proper instructions. A qualified plumber , plumbing supply location, or hardware store will have no problem
with alternative parts and advice necessary to install your unit.

Step 2: Place the drain saddle but do not tighten.

Placement of drain saddle should be located on the vertical tail piece of the plumbing system
at least 2” above the horizontal outlet or trap assembly .

NOTE: On the vertical pipe: The higher the placement on this pipe, the greater the chance of

increased noise in your waste line. Drain connection should be pointing out or towards you
as you look into the cabinet.
On the horizontal pipe as an alternate location: See illustration A, the drain saddle should be
at a 10 o’clock or 2 o’clock position

Step 3: Once the drain saddle is placed, use a 1/4” drill bit, and drill a hole slightly above the drain

saddle. Do not drill through the other side of the pipe.
Make sure the one hole is complete with clean edges and clear of debris.

WARNING: IF DRILLING MET AL PIPE, PROTECT YOURSELF FROM SERIOUS INJURY OR F A T AL
