PIPE, FITTINGS, OTHER MATERIALS NEEDED
You must first decide how to run "in" and "out" pipes to
the softener. Look at your house main water pipe at the
point you will connect the softener. Is the pipe soldered
copper, glued plastic, or threaded galvanized or brass?
What is the pipe size? What kind of pipe and fittings is it
easiest for you to work with, and what tools do you have?
Now look at the common plans for "in" and "out" piping
on soldered copper. See Fig. 6. Use it as a guide to plan
what materials you will need. Get all the materials you
will need before you start.
Use Fig. 5 to make a plan drawing for your specific
installation. "In" and "out" fittings included with the soften-
er are 1" NPT threaded adaptors. You should maintain
the same, or larger, pipe size as the water supply pipe,
up to the softener inlet and outlet. Use copper, brass,
galvanized or PVC plastic pipe and fittings for the "in"
and "out" pipes. Be sure to check local codes.
Note: If converting from galvanized to copper pipe
use approved dielectric insulating connectors.
ALWAYS install the bypass valve (that is included with
the unit) or a three valve bypass. See Fig. 9 to13.
Bypass valves let you turn off water to the softener if
needed for repairs, but still have water in the house
pipes.
Drain tubing (3/8" inside diameter), is needed for the
valve and salt tank drains. See Fig. 16. If a rigid valve
drain is needed to comply with plumbing codes, you can
buy the parts needed (see Fig. 16) to change the soften-
er to a 1/2 inch minimum copper tubing drain.
