amount
of

coming
out,
which
would
mean
you
have
very
high
water
pressure,
or
the
drain

control
for
the

is
missing.

If
possible
verify
that
the
backwash
flow
rate.
You
can
easily
run
the
drain
hose
to
a
bucket
and
using
a
watch
verify
the
flow
rate
in
gallons
per
minute.
For
example,
if
the
backwash
fills
a
5
gallon
bucket
in
30
seconds,
you
have
10
gallons
per
minute
or
10
GPM.
An
adequate
backwash
is
critical
to
properly
clean
the
Pro
‐
OX
media
and
prevent
it
from
cementing
together.

The
next
cycle
is
the
Rinse
cycle
and
this
runs
for
6
to
8
minutes.
After
the
backwash,
the
Fleck
7000
will
automatically
advance
to
the
rinse
cycle.

After
the
Pro

OX
filter
has
gone
through
the
backwash
and
rinse,
press
the
Extra
Cycle
button
and
repeat
the
backwash
and
rinse.
This
is
the
same
procedure
that
needs
to
be
done
each
time
you
add
Pro
‐
OX
media
in
the
future,
that
is,
the
Pro
‐
OX
media
must
be
thoroughly
backwashed
and
rinsed.

Maintaining
Your
Pro
‐
OX
Filter
System
There
is
little
or
no
maintenance
required.
Every
6
–
10
years
the
Pro
‐
OX
media
can
be
replaced
for
best
results.
If
your
water
has
a
lot
of
hydrogen
sulfide
odor
or
iron
and
manganese
levels
over
10
ppm,
a
chlorine
feed
pump
may
be
needed
to
inject
a
small
amount
of
chlorine
before
the
well
pressure
tank
and
Pro
‐
OX
filter.
The
Pro
‐
OX
will
remove
any
chlorine
tastes
or
odors.
In
most
cases
this
is
not
necessary
but
chlorination
(or
ozone,
or
peroxide
injection)
before
the
Pro
‐
OX
filter
can
greatly
enhance
the
ability
of
the
media
to
remove
iron,
manganese
and
hydrogen
sulfide.
