Before Starting Installation
Tools, Pipe, and Fittings, Other Materials

Pliers

Screwdriver

Teflon tape

Razor knife

Two adjustable wrenches

Additional tools may be required if modifi-
cation to home plumbing is required.

Plastic inlet and outlet fittings are included
with the filter. To maintain full valve flow,
3/4” or 1” pipes to and from the filter fit-
tings are recommended. You should main-
tain the same, or larger, pipe size as the
water supply pipe, up to the filter inlet and
outlet.

Use copper, brass, or PEX pipe and fittings.

Some codes may also allow PVC plastic
pipe.

ALWAYS install the included bypass valve,
or 3 shut-off valves. Bypass valves let you
turn off water to the filter for repairs if
needed, but still have water in the house
pipes.

5/8” OD drain line is needed for the valve
drain. A 10’ length of hose is included.
with some models.
pH
The pH of water measures its acidity or its
alkalinity. Water with a pH of less than 7.0 is
acidic, above 7.0 it is alkaline, and a pH of
7.0 is neutral. The lower the pH value is be-
low 7.0 the greater the acidity, and the high-
er the pH value is above 7.0 the more alka-
line. Acidic water (pH less than 7.0) is corro-
sive to pipes, appliances, etc. A pH of 7.0 or
higher facilitates iron removal
— which is
why the filter is designed to increase the pH
when it is less than 7.0.
TANNINS (Humic Acid)
Tannins (also known as humic acid) which
are present in some water supplies, are the
result of decaying vegetable matter. If the
tannin concentration is above approximately
0.5 ppm, it will form a sticky coating on the
media, thus rendering it incapable of filtering
the iron. A chemical free iron filter is not rec-
ommended under this condition. If the tannin
concentration is less than 0.5 ppm, a chemi-
cal free iron filter may be installed.
HYDROGEN SULFIDE (H2S)
Hydrogen sulphide (often referred to as
“sulphur”), is easily detectable by its objec-
tionable “rotten egg” odour. Sulphur corrodes
iron, brass, copper and silver. A chemical free
iron filter is capable of removing sulphur in
concentrations of up to 3 to 5 ppm. Whenev-
er hydrogen sulphide is present, backwashing
must be performed at more frequent inter-
vals.
