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.
Use a pit that conforms to all local codes, and check
the code to see if a gate valve or ball valve if is
required.
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 the
backup pump and the main pump do not touch each
other. Before starting the installation, clean the pit of
all debris. The pump’s strainer must be kept clear. The
pump should not be set directly onto a clay, earthen,
or sand base. You should install bricks or blocks under
the pump to provide a solid base and to raise the pump
off the sump pit floor. The pump should be level.
Install discharge plumbing according to local, regional
and state codes.
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.
