Introduction
The Basement Watchdog Big Dog backup sump
pump is designed as an emergency backup
system to support your main AC sump pump, and
it will automatically begin pumping any time the
float switch is activated by rising water.
The Basement Watchdog Sump Pump
System includes:
• A control unit with a dual float switch, a
battery fluid level sensor, battery cables, a
5 amp AC fuse, and a 20 amp DC fuse
• A plastic wire tie for mounting the float
switch
• A pump with a 1½” pipe adapter
• A battery box
• A battery cap with a hole to accommodate
the fluid sensor
If your main AC pump breaks or is unable to keep
up with all the incoming water, the Basement
Watchdog pump is capable of running without
discharging the battery as long as the AC power
is on. As soon as the AC power is interrupted,
the battery takes over. Should any malfunction
or emergency occur that involves the sump
pump, the battery, or the AC power, the
Basement Watchdog system will sound an alarm.
A light on the display panel of the control unit
will indicate the cause of the alarm and the
corrective action.
You will also need to supply:
• A Basement Watchdog 7.5 Hour Standby
Battery
DO NOT use an automotive battery with this
system
DO NOT use a maintenance-free or sealed
battery with this system
DO NOT use a Basement Watchdog Emergency
battery with this system. It will not run the
pump as long as the 7.5 hour battery
The internal construction of some wet cell
batteries may not be compatible with this
For added reliability, the float switch has, not one,
but two floats. Should one float fail to operate, the
second float automatically activates the pump.
To extend the battery run time, two batteries
may be connected to the Basement Watchdog
Big Dog system by purchasing a second battery
and acid pack, as well as a set of battery jumper
system. Glentronics can not guarantee the
compatibility of other brands of batteries.
The use of a Basement Watchdog battery is
HIGHLY recommended.
• 1½” rigid PVC pipe and fittings
• PVC primer and cement
• A union with hose clamps or a “Y” connector
and two (2) check valves, depending on the
installation method you use
• A surge protector (recommended)
• Six (6) quarts of 1.265 specific gravity
battery acid
For narrow sump pits you will need
some additional parts:
• An “L” bracket at least six (6) inches long
(preferably one that will not rust)
• Two (2) stainless steel hose clamps
• One (1) stainless steel screw (#8-32 x
3/4”), a matching washer & nut
Battery Box
Control Unit
To connect two batteries you will need:
• Two (2) batteries of similar age and capacity
(so they will have equal power)
• Another battery box (optional)
Pipe

Installation Instructions
NORMAL SUMP PIT
INSTALLATIONS
Whenever possible, install your Basement
Watchdog backup pump with a direct discharge
to the outdoors. By using this method, there will
always be an outlet for the water from the sump.
During times of very heavy rain, many storm
sewers fill up. If your pump is trying to
discharge water into a full sewer, there is
nowhere for the water to go. By discharging
directly outdoors, there is always an outlet for
the water that is pumped out of the sump. For
this method, you will need to drill a hole through
a floor joist or the foundation from the basement
to the outside of the house.
If the direct discharge method is not possible or
convenient, the Basement Watchdog pump can
be connected to the same line as your main AC
sump pump by installing a “Y” connector and
two (2) check valves.
FLOOR
JOIST
FLOOR
JOIST
There are two basic methods that can be used to
install the pump, a direct discharge to the
outside of the building, or a connection to an
existing discharge pipe. The same two options
apply in very narrow sump pits where the backup
pump must be mounted above the main pump.

In most cases, the backup pump will fit next to
the main AC pump in the sump pit. In very
narrow pits, the backup pump can be mounted
above the main AC pump. Try to fit the backup
pump on the floor of the sump first. Make sure
there is enough room so that the battery backup
pump and the main pump do not touch each
other.

Installation Instructions
INSTALLATION A:
DIRECT DISCHARGE TO THE OUTSIDE OF
THE BUILDING (Diagram A)
! DANGER
Unplug the main AC pump when installing
the backup pump to avoid electric shock.
Failure to do so could cause serious injury
or death.
1. Cut a piece of 1½” rigid PVC pipe long
enough to reach from the bottom of the sump
pit to one (1) foot above the floor. Prime and
cement it to the 1½” pipe adapter, then
screw the adapter into the pump.
2. Secure the pump wire so that the plug on the
end will not fall into the sump. Attach the
wire to the pipe with a piece of tape.
3. Place the pump with the PVC pipe attachment
on the bottom of the sump floor next to the
main AC pump. The pumps should not touch
each other. Do not mount the pump to any
existing pipes; it should be placed on the
floor of the sump. A brick may be placed
under the pump if there are rocks or other
debris on the sump floor that may clog the
pump.
4. Attach a union or a check valve to the top of
the 1½” pipe. This will allow the pump to be
removed easily, should the need arise.
The path of the rest of the pipe and the details
of each installation will vary. Using sound
plumbing practices, try to route the discharge
pipe to an exterior wall via the shortest path
with the fewest turns. More turns will reduce the
pumping capacity. The pipe section exiting the
building should be on a downward slope so that
the water in the pipe will exit outside instead of
returning to the sump pit. Be sure to seal the
hole in the wall where the pipe exits, and prime
and cement or clamp all connections securely to
prevent leaking. When directly discharging to
the outside of the building, no check valve is
required. However, a check valve will prevent
water from flowing back into the pit when the
pump has stopped.
CAUTION
If you use more than a total of 20 feet of
pipe (including vertical and horizontal runs)

in the installation, install a check valve in
place of a union. Make sure it is installed
with the arrow pointing up, or it will not
prevent the backflow of water. When a check
valve is used, a 1/8” hole must be drilled in
the PVC pipe above the Basement Watchdog
pump. Drill the hole at a 45° angle toward
the bottom of the sump to avoid splashing
water outside the sump pit. Make sure the
hole is above the water line and below the
check valve. If a hole is not drilled above
the pump, an air lock may prevent the pump
from operating.

Depending on your installation requirements,
PVC pipe lengths will vary. Cut the pipes and
assemble them as shown in photo #7. Do not
cement them together until you are sure they are
cut to the correct lengths. It is important to keep
the discharge pipes on both pumps parallel to
each other, so that the pumps remain flat on the
floor of the sump. More detailed instructions
follow.

Battery Instructions
A new Basement Watchdog 7.5 Hour Standby
Battery will run this system for a minimum of 7.5
hours continuously. However, most of the time
the pump will turn on and off, and this battery
will run the pump intermittently for days. To
increase the running time of this system to 15
hours of continuous pumping, two batteries can
be connected together. Ideally the batteries
should be of similar age and capacity. Connecting
an old and new battery together will not charge
properly. Specific connection instructions will be
explained below. In addition, the unique
materials in the Basement Watchdog 7.5 Hour
Standby batteries enable them to last for five to
seven years in standby service.
CAUTION
• The use of automotive batteries is NOT
recommended. Automotive batteries are not
designed for this application. They will only
run the pump for a short time and will have
a shorter life than a standby battery.
• NEVER use a maintenance-free battery
with this system
• The battery fluid sensor is designed to fit
the Basement Watchdog Standby batteries.
Measuring the battery fluid is one of the
most important features of the system,
since about 80% of backup sump pump
failures are the result of a battery that has
dried out.
• The internal construction of some wet cell
batteries may not be compatible with this
system. Glentronics can not guarantee the
compatibility of other brands of batteries.
The use of a Basement Watchdog battery is
HIGHLY recommended.
! DANGER
DO NOT insert the fluid sensor into any
battery except a Basement Watchdog battery.
DO NOT drill a hole in another brand of
battery to accommodate the fluid sensor.
DO NOT use the enclosed battery cap on any
battery except a Basement Watchdog battery.
DO NOT drill a hole in the cap of another
brand of battery to accommodate the fluid
sensor. Batteries emit explosive gases,
which can cause serious injury or death.
PREPARING THE BASEMENT WATCHDOG
STANDBY BATTERY
The Basement Watchdog Standby batteries are
shipped dry (without acid) so they never lose
power before you take them home. A battery is
activated when the acid is added, and then it
slowly begins to deteriorate as it ages. By
adding the acid just before use, the battery will
always be fresh. Use 1.265 specific gravity
battery acid to fill the battery. It is available
where you purchased the battery.
the hose with thumb and forefinger. Fill each
cell of the battery to a level just covering
the battery plates, and then go back and top
off each cell equally. It is important to have
all the cells filled equally or the battery will
not operate properly. The acid should reach a
level about ¼” below the cap ring as shown in
the diagram at right. DO NOT OVERFILL THE
BATTERY. (Diagram E)

NOTE: Basement Watchdog batteries now come in
two configurations. The tops of the batteries look
different, and the directions for filling the
batteries and connecting the fluid sensor will vary
slightly. If the top of your battery looks like
photo A, follow the instructions on this page. If
the top of your battery looks like photo B on page

Battery problem
This light and alarm will come on when the
control unit detects there is less than one (1)
hour of pumping power left in the battery, or
that the battery is defective. The alarm cannot
be silenced, because action needs to be taken to
protect your basement. If your battery is more
than five (5) years old, replace it. If not, here
are several situations that would cause the pump
to run the battery for an extended time and
discharge the battery: Check the list below
before you replace the battery.
• If the 3rd light on the controller is also on,
it means that the unit is not receiving AC
power. Either the AC power is out, the
circuit breaker has blown, or the outlet is
bad. When the problem is corrected, the
battery should recharge.
• If the 5th light on the controller is also on,
check your main pump for failure. The
backup pump may have been activated
repeatedly if your main AC pump is broken,
or you are experiencing heavy rains and your
main pump cannot keep up with the inflow
of water. You may need to upgrade or
replace your main pump. When the problem
is corrected, the battery should recharge.
• If no other lights are on, this means the
terminals may be corroded, and the battery
cannot charge properly. Unplug the charger
from the wall outlet. Then, check the
battery cables and the battery terminals for
corrosion. Clean and tighten them as
needed. The procedure is described in the
next column.
• If the battery terminals have been cleaned
and the light is still on, there could be a
problem with the controller or the battery.
The best way to determine if the battery is
the problem is to have it charged and load
tested at any local car service station. If
the battery is bad and less than one (1) year
old, it can be returned to the place of
purchase for a replacement (receipt
required). If the battery is good, contact
Glentronics’ service department for further
instructions. The phone number is 800-9910466, option #3.
If the battery alarm goes on while the pump is
running and the power is out, you will have a
minimum of one (1) hour of continuous pumping
time to replace the battery. (In most cases, the
pump does not run continuously, and therefore,
you actually have a longer time to replace it.)
You will not be able to silence the alarm. Left
unattended, the basement will flood. In a
severe emergency, if a replacement battery is not
available, you could temporarily use your car
battery, or recharge this battery by connecting it
to your car battery.
Once the AC power is restored, the battery will
recharge automatically, unless it is old or
damaged. The alarm will remain on until the
WHITE button is pressed for one (1) second.
In the event that your Basement Watchdog sump
pump system has pumped for an extended period
of time, the battery may be very depleted. In
this condition, when the AC power is returned to
the unit, a battery alarm will continue to sound.
The battery may need a longer period to
recharge. Press the WHITE button for five (5)
seconds to silence the alarm.
If the battery is completely discharged, an
internal safety feature will not allow the
charging system to activate. Call the Glentronics
service department for instructions or replace
the battery.

TESTING THE FLOAT SWITCH
LIFT
FLOAT
Lift the float up and let go. This will activate
the pump. The control unit will run the pump
for approximately 25 seconds so it can empty all
the water in the sump pit. While the pump is
active, water will come out of the 1/8” hole that
was drilled into the PVC discharge pipe. This is
normal. The hole is needed to prevent an air
lock within the system. DO NOT obstruct the
hole or an air lock may prevent the system from
activating. If there is no water in the pit, the
pump can run dry for this amount of time. The
alarm will sound and the “Pump was activated”
light will go on. After the pump has stopped,
push the WHITE button on the front of the
control panel to silence the alarm. If the WHITE
button is pressed before the pump has stopped,
the alarm will go off temporarily. Wait for the
pump to stop pumping, and then push the
WHITE button to completely silence the alarm.
BE SURE TO PLUG IN THE MAIN AC PUMP WHEN
YOU HAVE COMPLETED THE TEST.
7. Remove the fluid sensor and yellow cap from
the battery and rinse any residue buildup from
the bottom of the battery cap. Replace the
cap and fluid sensor.
8. Check battery fluid levels.

AC PUMPS
FLOAT SWITCHES
Industrial Grade Pumps for the
Residential Market
What’s the most common reason your
main AC pump fails?
The Basement Watchdog line of AC sump pumps
are strong, dependable and so energy efficient,
they could pay for themselves in a few years.
The sump pumps are equipped with dual float
switches for added reliability. When your main
AC pump needs replacement, consider
upgrading to one of the pumps in the
Basement Watchdog line.
It’s probably the result of a float switch that is
stuck or broken. Replace it with a Basement
Watchdog dual float and controller for reliable
operation. The dual float has, not one, but two
floats mounted within a protective cage. Should
one float fail to operate, the second float
automatically activates the pump.
The
protective cage prevents debris or other wires
from interfering with the movement of the float.
It can be used to replace the float on most AC
pumps.
CHECK VALVES
WATER ALARMS
What’s a Klunkless Check Valve™?
Minimize the risk of water damage
If you’ve spent any time in your basement,
you’ve probably noticed your sump pump turning
on and off with a loud clunk. That’s the result
of the water pressure slamming the valve closed
in the check valve. The Klunkless Check Valve
has a built-in air chamber to counteract that
pressure and muffle the sound. It works just like
a conventional check valve, only quieter.
You can detect leaks before they become bigger
problems by placing a water alarm wherever
there is a risk of water damage…in the utility
room, laundry room, kitchen, bathroom or
basement. The alarm will sound when as little as
1/32” of water reaches the sensor.
