Owner manual

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 7.5 Hour Standby
Battery
DO NOT use an automotive battery with this
system
DO NOT use a maintenance-free or sealed

• 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
