To connect two batteries you will need:
 Two (2) batteries of same type, age and capacity (so
they will have equal power and charge properly). Do
not use batteries of different types, ages or
capacities.
 Another battery box
 Two (2) acid
packs to fill the
dry batteries.
Acid packs are
not needed if
using
maintenance free
(AGM) batteries

Introduction
The Basement Watchdog combination sump pump system is
designed to provide both primary and backup pumping
capabilities. The primary pump will operate as long as it is
receiving AC power. If the power is interrupted, or more
water is coming into the sump than the AC pump can
handle, the backup sump pump will begin pumping
automatically. The backup system has unique monitoring
features that diagnose a problem and sound an alarm. A
light on the display panel of the control unit will indicate
the cause of the alarm and the corrective action. The two
systems have been pre-assembled for easy installation.
For added reliability, the float switches have, not one, but
two floats. Should one float fail to operate, the second
float automatically activates the pump.
The Basement Watchdog Sump Pump System includes:
 A 1/2 HP primary pump with a caged dual float switch,
and a blue piggyback controller that plugs into the
wall outlet
 A black backup pump supported by a bracket
 A black control unit for the backup pump with a battery
fluid sensor, a dual float switch, and battery cables

Two cable ties to secure the wires to the discharge pipe
 A battery cap with a hole to accommodate the fluid
sensor
 A battery charger
 A rubber union
You will also need to supply:
 A Basement Watchdog Big Standby Battery or
Maintenance Free (AGM) Standby Battery.* DO NOT
use
a Basement Watchdog Emergency Standby Battery
(24EP6 of BW-24F) with this system. It will not run
the pump as long as the Big Standby or Maintenance
Free (AGM) Standby Battery.
 Six quarts of 1.265 specific gravity battery acid. (Not
needed if using a maintenance free (AGM) standby
battery.)
*Basement Watchdog standby batteries are specifically
designed to work with your battery backup sump
pump system. Glentronics can not guarantee the
compatibility of other brands of batteries. For
optimal
performance
the use of a
Basement
Watchdog
standby
battery is
recommended.
For some installations you may
also need additional items:
 1-1/2” rigid PVC pipe
 A 1-1/2” PVC pipe connector
or a 1-1/2” rubber union
 PVC pipe cleaner and cement
 A set of battery cables with rings on both ends
to connect the two batteries together
