Pump & Pipe
Installation Instructions
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.
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.
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 backup pump
and the main pump do not touch each other.
Select the installation method that will best suit
your needs from the diagrams at the right. Full
instructions for each installation method are
provided on the following pages.
Installation will take a couple hours.
