This is definitely
THE water powered
backup sump pump
for the discerning
professional.
It's the one to
get when you need
strong pumping capacity,
which all Basepumps
offer, but also
the strength and
confidence that
an all-brass inlet
and control valve
can give you. You
are the Professional
who can and will
appreciate the design
and sense of strength
this gives you the
moment you pick
it up. We use only
the finest quality
materials in all
our products, and
for this one, we've
gone even further.
The valve can withstand
pressures of 150
Lbs. PSI and the
brass vacuum breaker
with its built-in
6" riser, qualifies
to meet code everywhere.
Built-in All Brass
Back-flow Prevention
The Atmospheric
Vacuum Breaker
is built in
so no additional
backflow protection
should be required,
when installed
in its correct
position on
the ceiling
joist in the
general area
above the sump.
We've included
a brass shutoff
valve so the
installer need
not provide
one.
The main
control valve,
or ejector valve
as we call it,
can withstand
higher pressures
(up to 150 Lbs.
PSI) than our
standard polypropylene
one. Same
reliable performance,
more strength
and durability.
Once installed
according to
directions,
there should
be no further
question about
it's safety
or reliability.
This makes it
possible to
meet the codes
and also keep
the costs down.
Always check
with your local
plumbing department
if you have
any questions.
Meets Professional
Standards for both
Commercial and Residential
Properties
Larger commercial
projects are now
able to see the
value and quality
of a Basepump. These
types of properties
and their owners
or managers, are
more likely to appreciate
the quality and
strength of this
model over our other
models with our
standard valves.
The higher pressures
and pumping needs
often found in these
buildings, used
to cause them to
shy away from such
products. Now there's
no excuse. This
is the best of the
best when it comes
to water powered
backup sump pumps.
Basepump Sump Level
Alarm included!
Cross-connection
must not be
subject to back
pressure or
continuous pressure.
Install
AVB at least
6" above the
highest point
of discharge.
Protection is
afforded against
back siphon
only. The configuration
of the pump
provides this
6" rise and
the discharge
must continue
on a level or
downward slope
to the exterior
so as to self-drain.
See a drawing
of a correct
installation
shown here to
the right.
The discharge
slopes down
and away from
Basepump and
directly outdoors.
Do not
connect
the discharge
from the Basepump
-AVB into the
discharge from
the primary
sump pump. It
will cause the
primary pump
to send water
back to the
Basepump and
spill from the
Vacuum Breaker.
The Basepump
ejector is mounted
on the ceiling
in the general
area above the
sump pit, discharging
as directly
as possible
to the outdoors.
If it cannot
be installed
this way for
any reason,
it will not
work properly
and will not
protect the
potable water
supply. The
"S" shaped section
from the AVB
valve to the
Tee
may be
removed if
absolutely
necessary for
installation
in tight spaces,
but the 6" downward
slope of the
discharge MUST
be maintained
to the exterior,
with
no upward sections
of any kind.
The suction
pipe is open
at the bottom,
allowing the
sump water to
drop into the
sump after each
pumping cycle.
The Basepump
is typically
mounted 6 to
10 feet above
the sump water.
The discharge
piping is vented
to atmosphere
and empties
at least 6"
below the AVB
Valve of Basepump.
There must be
no back-pressure
on the Basepump
Ejector when
it is not running.
The Basepump
suction and
discharge pipes
are empty of
sump water unless
the pump is
operating.
Specify
the Basepump
Model you want
with the -AVB
suffix. For
example: RB750-AVB.
Atmospheric Vacuum
Breaker (AVB) is
always placed downstream
from all shut-off
valves. Its air
inlet valve closes
when the water flows
in the normal direction,
but as water ceases
to flow, the air
inlet valve opens,
thus interrupting
the possible back
siphon effect. If
piping or a hose
is attached to this
assembly and run
to a point of higher
elevation, the back-pressure
will keep the air
inlet valve closed
because of the pressure
created by the elevation
of water. Hence,
it would not provide
the intended protection.
Therefore, this
type of assembly
must always be installed
at least six (6)
inches above all
downstream piping
and outlets. Additionally,
this assembly may
not have shut-off
or obstructions
downstream. A shut-off
valve would keep
the assembly under
pressure and allow
the air inlet valve
(or float check)
to seal against
the air inlet port,
thus causing the
assembly to act
as an elbow, not
a back-flow preventer.
The AVB may not
be under continuous
pressure for this
same reason. An
AVB must not be
in
continuous
use for more than
twelve (12) hours
out of any twenty-four
(24) hour period.
(Note: Each time
it starts, a new
12-hour cycle begins.)
It may be used to
protect against
either a pollutant
or contaminant,
but may only be
used to protect
against a back siphon
condition.
