Instructions / Assembly
Introduction
The Basement Watchdog Special backup sump
pump system is battery-operated. It 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. 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.
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.
The Basement Watchdog Special Sump Pump
System includes:
• A control unit with a dual float switch, a
battery fluid level sensor, battery cables, and a
20 amp fuse
• A pump with a 1½” PVC pipe adapter
• A plastic wire tie for mounting the float switch
• A battery box
• A battery charger
• A battery cap with a hole to accommodate the
fluid sensor
You will also need to supply:
• A Basement Watchdog Big Standby Battery
(30HDC140S or BW-30F)
DO NOT use an automotive battery with
this system
DO NOT use a Basement Watchdog Emergency
Standby Battery (24EP6 or BW-24F) with this
system. It will not run the pump as long as
the Big Standby Battery
• 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
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)
• Two (2) acid packs to fill the dry batteries
• A set of battery cables with rings on both ends
to connect the two batteries together

Use of a Basement
Watchdog Klunkless
Check Valve™ will
provide quieter
operation. (See
