The drain line tubing (not supplied) is connected to a drain from the drain outlet using flexible ½” ID
tubing. Note that the drain can run up above the 5900e control and into a drain, it does not have to
drain down, as the filter backwashes 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.
