This
situation
can
be
caused
by
simply
using
more
water
out
of
the
Bubble
‐
Up®
Jr
than
what
is
coming
in.
Compare
water
outlet
flow
with
“current
flow”
meter
control
reading
on
the
Bubble
‐
Up®
Jr
while
filling.
A
few
inlet
flow
problems
are;
low
yield
well,
well
pump
failure,
clogged
plumbing
or
water
filtration
restricting
water
flow
filling
the
Bubble
‐
Up®
Jr.
No
water
from
the
Bubble
Up
(alarm
is
sounding)
Cause:
Water
Alarm
Valve
shut
water
off
to
Bubble
‐
Up®
Jr.
Example:
The
Bubble
‐
Up®
Jr
Interactive
includes
a
water
alarm
valve
which
sounds
an
alarm
and
stops
water
filling
the
Bubble
Up
when
a
leak
or
overflow
condition
is
detected.
Once
water
stops
filling
the
Bubble
‐
Up®
Jr,
continued
water
use
will
cause
the
low
water
float
switch
to
stop
the
Bubble
Up
pump
from
delivering
water
flow
to
the
house.
Examples:
The
alarm
conditions
to
cause
the
water
alarm
valve
to
close
and
stop
water
from
entering
the
Bubble
‐
Up®
Jr
are;
1
‐
the
water
sensor
box
detects
water
on
the
floor
around
the
Bubble
‐
Up®
Jr
2
‐
the
water
sensor
terminal
block
detects
water
on
top
of
the
Bubble
‐
Up®
Jr
or
3
‐
the
high
water
float
switch
senses
high
water
in
the
main
tank.
These
conditions
are
caused
by
water
detection
due
to
high
water
levels,
water
leaks,
condensation
Etc.
Also
if
the
air
vent
piping
is
restricted
the
Bubble
‐
Up®
Jr
blower
cannot
freely
blow
the
air
out
of
the
Bubble
‐
Up®
Jr.
This
will
cause
blower
back
pressure
which
will
force
water
up
the
overflow
pipe
to
be
released
through
the
breather
vent,
causing
the
sensors
on
the
terminal
block
to
detect
an
overflow
of
water.
Vent
piping
back
pressure
can
be
caused
by
an
obstruction,
ice
build
‐
up,
water
trapped
in
a
reverse
pitch,
excess
pipe
fittings
or
pipe
length.
High
‐
Water
Alarm
A
few
things
can
cause
the
high
‐
water
alarm
valve
control
to
sound:
The
leak
detection
terminal
block
or
floor
sensor
is
wet,
repair
leak
and
dry
off
the
top
of
the
Bubble
‐
Up®
Jr
Interactive™.
Vent
line
is
obstructed,
forcing
the
water
up
the
overflow
and
triggering
the
terminal
block
sensors.
Clear
obstruction.
High
water
alarm
float
is
triggered
due
to
overfilling
the
main
tank
of
the
Bubble
‐
Up®
Jr
Interactive™.
This
can
be
caused
by
a
failed
or
stuck
solenoid,
tangled
float
switch
assembly,
or
a
failed
float
switch
assembly.
Check
to
see
that
solenoid
and
float
switch
are
working
properly
and
replace
if
necessary.

Here
are
some
points
to
keep
in
mind
when
replacing
parts:
•
Before
removing
any
parts,
shut
off
the
water
inlet
to
the
Bubble
‐
Up®
Jr
Interactive™.
Set
the
handles
on
the
bypass
valve
to
the
bypass
position.
•
Always
unplug
all
of
the
power
cords
before
working
on
the
unit.
•
Notice
that,
inside
each
end
of
the
blue
water
tubing
there
is
a
stainless
steel
insert
and
a
plastic
ferrule.
This
is
an
important
part
of
the
connection.
You
may
need
to
replace
this
ferrule
when
you
replace
one
of
these
connections.
