Okay,
taken
apart
of
the
high-pressure
water
pump,
there's
the
way
it
works
is
to
check
valves
11
here,
that's
the
actual
hexagonal
fitting
hex
valve
proper
check
valve
check
valve
right
there
that
says
neutral,
n,
EU
dash
trol,
that's
the
company
that
makes
these
little
check
valves
right
here.
I
know,
there's
a
pressure
gauge
here.
It
goes
all
the
way
to
3000
psi.
This
is
the
water
outlet.
A

Then
the
water,
because
the
water
actually
comes
in
here,
okay,
so
that
when
you
pull
that
back
it
draws
it
in
mm-hmm,
then
you
push
it
out.
It
can't
go
back
through
the
check
valve.
It
has
to
go
that
way.
Yeah
and
then
there's
a
check
valve
here,
because
if
you,
if
you
didn't
have
this
check
valve
the
boiler
or
whatever
your
pressure
checking,
the
pressure
would
want
to
come
back
through
here
and
it
would
blow
this
out
of
here.
Boo
boo.
A
B
Would
have
it
in
there?
He
obviously
designed
it
to
have
that
in
there
for
some
reason
and
I'm
and
I'm
sure
it
was
for
lubrication,
because
there's
no
other
way
to
lubricate
this
thing.
So
it's
just
a
pocket
where
you
can
keep
some
grease
in
there
and
does
the
length
of
that
matter.
You
think
I,
don't
know
I,
don't
know
I,
don't
have
any
specifications
on
it
or
how?
How.
