Parts required

 

(Not Included)

(2x) Hex nipples or pipe nipples   (2x) Shutoff valves (as needed)
(2x) Pipe union pressure regulators (as needed)

Pre-installation

• 

 Turn off the water to your house before beginning the installation. Turn off power 

to your water heater before installation. Open all plumbing fixtures in the house to 
drain the lines of water and pressure.

•  

Lay out all the fittings and tools you will need to install the system depending on 

your configuration. Be sure to use Teflon tape on threaded fittings.

•  

Measure, cut, and remove the section of water line where the system is to be 

installed. When determining the length of pipe to cut, account for filter width, shutoff 
valves, union fittings, nipple fittings, pressure gauges (if used) and bypass valve (if used).

•  

Allow the cut line to drain. Smooth the newly cut ends down to avoid jagged 

points or edges.

•  

A three-valve bypass valve and loop may be installed to loop the entire system to 

make servicing easier.

• 

 The filter should be placed on the main water supply line near where it enters the 

house at any point past the main shutoff valve for the whole house, but before pipes 
branch off into multiple directions. However, you may choose to locate the filter after 
the line branches to the inside and outside plumbing depending on your filtration 
intent. Your filter should be located in a dry, level area and protected from freezing 
temperatures and direct sunlight.

Installation

Step 1: Select connection method according to pipe’s size

Please select the appropriate connection method according to the size of the pipe in 
your home. Please pay attention to the direction of water flow when installing. Take 
the 1” MNPT thread specification and 1” PEX pipe as an example:
