Introduction
The Basement Watchdog A/C-D/C backup sump
pump system is strong enough to be used as
your main and only pump, but we recommend
using it as an emergency battery backup system
to support your regular AC sump pump. It has a
state-of-the-art monitoring system, and it will
automatically begin pumping if your main AC
pump fails. Should any malfunction or
emergency occur that involves the sump pump,
the battery, or the AC power, your 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.
If the 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.
