EQUIPMENT INSTALLATION
If you are also installing a water softener, the softener should
be installed downstream of this system.
Grounding the Plumbing
It is important that the plumbing system be electrically
grounded. When a water treatment system is installed a
nonmetallic bypass valve may interrupt the grounding. To
maintain continuity, a grounding strap can be purchased at a
hardware store. When it is installed the strap will connect the
plumbing into the system to the plumbing leaving the system.
Water Line and Bypass Connection
Once you have selected your location check the direction of the
water flow in the main pipe.
A bypass valve system should be installed on all water
conditioning systems. The bypass valve system isolates the
filter from the water supply and provides untreated water to
service during routine maintenance and servicing procedures.
