SECTION III: PREPARATION 

 

 
A. Major System Components 

 

 

The following components comprise the NRS-1 
Drinking Water System: 

 

1. A Nitrate Reduction assembly consisting of the 

aluminum bracket, screws, wrench, filter 
housing, installed nitrate filter, installed shut-off 
ball valve with fittings.  

  
2. An automatic shut-off water meter with installed 

fitting on OUTLET.  

 
3. A faucet kit with ¼” fitting. 
 
4. A plastic tubing kit with feed water supply valve 

and leak stop valve. 

 
5. 

Other items necessary for installation may 

include wood screws or machine screws for 
mounting the NRS-1 assembly, concrete 
anchors may be required for hanging on 
basement wall, additional tubing or tube 
connectors, and plastic wire ties for organizing 
tubing. 

 

B. Tools Recommended for Installation 

 

The following tools will cover most of the installation 
sites encountered: 

  3/8" variable speed electric drill.  

  Extension work light with outlet.  

  Safety Glasses.  

  1-1/4" porcelain hole cutter kit.  

  1-1/4" Greenlee hole punch and 1/8" and 

1/2"metal drill bits for pilot hole.  

  Center punch and hammer.  

  1-1/4" wood bit.  

  Assorted wood and metal drill bits including 

7/32" metal drill bit.  

  Phillips head and flat blade screwdrivers.  

  1/2", 9/16" and 5/8" open end wrench.  

  10" Crescent wrench with jaws taped to 

hold faucet.  

  Teflon tape.  

  Wide masking tape or duct tape.  

  Plastic tubing cutter.  

  Extra plastic tubing.  

  Small bottle of liquid chlorine bleach.  

 

 

C. Determine System Location  

 

The NRS-1 system can be located under a sink or 
in a basement depending on space availability and 
the custom

er’s preference.  If a basement 

installation is selected, additional tubing, hardware 
and fittings may be needed and a hole will have to 
be made from inside the cabinet, through the floor, 
to the basement. Never install in an area of the 
home where temperature is freezing as damage to 
the system will result. If a reverse osmosis system 
is to be installed in-line with the NRS-1, the NRS-1 
should be the last device before the faucet. 
 
Considerations for an ice maker or other remote 
hook up should be determined, including routing 
and any additional tools, fittings, and tubing that 
may be required. 

 

1)  Faucet - The faucet should be placed near 

the sink where drinking water is normally 
obtained. Convenience of use (filling of 
water pitchers and glasses), and an open 
area beneath the faucet under the sink for 
attaching product tubing are considerations.

 

A 2" diameter flat surface is required above 
and below the mounting site.  The thickness 
of the mounting surface should not exceed 
1-1/4".Watch for strengthening webbing on 
the underside of cast iron sinks.

  

2)  NRS-1 Assembly - The NRS-1 Assembly 

may be mounted on either the right or left 
side of the under-sink area or a cabinet.  
Mounting in the basement is also an option. 
The mounting location should allow 
adequate clearance and accessibility for 
cartridge changes. 

 

3)  Feed Water Connection - The feed water 

valve should be located as close to the 
NRS-1 assembly as possible.  

 

4) 

Leak Stop Valve 

– Drinking water systems 

inherently have many connections which 
could leak.  It is necessary to install the 
included Leak Stop Valve very close to 
and/or under the NRS-1 assembly.  It must 
be fastened to the floor or cabinet base with 
screws or double-sided tape.  The feed 
water supply must pass through the Leak 
Stop Valve (See page 9).  Should a leak 
occur and the underside of the Leak Stop 
Valve gets wet, the feed water will be 
terminated.  Once activated, the Leak Stop 
Valve can be reset one time (See page 12).
