Installation Instructions

DIRECT DISCHARGE TO THE OUTSIDE OF THE
BUILDING (Diagram A)
DANGER
!
Unplug the main AC pump when installing
the backup pump to avoid electric shock.
Failure to do so could cause serious injury
or death.
1. Cut a piece of 1½" rigid PVC pipe long
enough to reach from the bottom of the
sump pit to one (1) foot above the floor.
Prime and cement it to the 1½" pipe adapter,
then screw the adapter into the pump.
2. Secure the pump wire so that the plug on the
end will not fall into the sump. Attach the
wire to the pipe with a piece of tape.
3. Place the pump with the PVC pipe
attachment on the bottom of the sump floor
next to the main AC pump. The pumps
should not touch each other. Do not mount

the pump to any existing pipes; it should be
placed on the floor of the sump. A brick may
be placed under the pump if there are rocks
or other debris on the sump floor that may
clog the pump.
4. Attach a union or a check valve to the top of
the 1½" pipe. This will allow the pump to be
removed easily, should the need arise.
The path of the rest of the pipe and the details
of each installation will vary. Using sound
plumbing practices, try to route the discharge
pipe to an exterior wall via the shortest path
with the fewest turns. More turns will reduce the
pumping capacity. The pipe section exiting the
building should be on a downward slope so that
the water in the pipe will exit outside instead of
returning to the sump pit. Be sure to seal the
hole in the wall where the pipe exits, and prime
and cement or clamp all connections securely to
prevent leaking. (No check valve is needed with
this method of installation as long as you use
less than 20 feet of pipe.)
CAUTION
If you use more than a total of 20 feet of
pipe in the installation, install a check valve

in place of the union. Make sure it is
installed with the arrow pointing up, or it
will not prevent the backflow of water.
When a check valve is used, a 1/8" hole
must be drilled in the PVC pipe above the
Basement Watchdog pump. Drill the hole at
a 45° angle toward the bottom of the sump
to avoid splashing water outside the sump
pit. Make sure the hole is above the water
line and below the check valve. If a hole is
not drilled above the pump, an air lock may
prevent the pump from operating, and the
basement will flood.
