To begin the installation process, follow these steps:

Turn off the main water supply line.
Release water pressure in the line by turning on all faucets
connected to the line.

STEP 3

Mark Measurements and Cut the Plumbing Pipe
We recommend a 3-way bypass installation using 3 ball valves. The picture shows the unit in “Service” position. Valves on the left and the right are open; center valve is closed. Water flows through the filter.

To bypass, close the right and left valves and open the center. Water flows around the filter.

The bypass will work without the right or the left valve, but it’s best to have both because it allows isolation of the filter completely from the house plumbing if desired.
CAUTION
Please wear safety glasses to protect eyes when cutting.
