under line pressure from your well pump. Most plumbing codes require an air-gap connection,
so that if your sewer or septic tank backs up, it cannot cross connect with the drain tubing.
Installation of Your System Into Copper or Metal Piping Systems:
If your new filter system is to be installed in a metal (conductive) plumbing system, i.e. copper or
galvanized steel pipe, the plastic components of the system will interrupt the electrical continuity of
the plumbing system.
As a result, any stray currents from improperly grounded appliances downstream or potential
galvanic activity in the plumbing system can no longer ground through the contiguous metal
plumbing.
Some homes may have been built in accordance with building codes, which encouraged the
grounding of electrical appliances through the plumbing system.
Consequently, the installation of a bypass consisting of the same material as the existing plumbing,
or a grounded "jumper wire" bridging the equipment and reestablishing the contiguous conductive
nature of the plumbing system must be installed prior to your systems use.
This is simple and easy step to take if you are installing your water treatment system into copper
piping. A simple ground jumper wire with a pipe clamp can be purchased at any Home Center, or
hardware store etc. for a few dollars.
How Your Carbon Filter Works:
See Fig 1 on the right. In your Carbon Filter the water enters the
top of the tank (red arrows) and flows down through the media
and up the distributor tube (blue arrows). The downflow type
Carbon Filter removes sediment and can be backwashed, which
cleans and re-classifies the Carbon, preventing channeling. During
backwash the flow of water is reversed and water flows down the
distributor tube and up through the media, lifting and expanding
the Carbon media. During the backwash the Carbon is cleaned by
the action of the water flowing through it.
