Pump & Pipe
Installation Instructions
INSTALLATION A:
DIRECT DISCHARGE TO THE OUTSIDE OF THE
BUILDING (Diagram A)
sDANGER
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 four-foot (4’) piece of 1
1
⁄2” rigid PVC
pipe and cement it to the pipe adapter that
is attached to the elbow on 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 4’ PVC pipe
attachment on the bottom of the sump floor
next to the main AC pump. 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 rubber union or check valve (sold
separately) to the top of the 1
1
⁄2” 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. Extend the
discharge pipe outside the building as far as
possible to avoid the return of discharged water
to the sump. Be sure to seal the hole in the wall
where the pipe exits 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 rubber 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 3” above the Basement
Watchdog pump. If a hole is not drilled above
the pump, an air lock may prevent the pump
from operating, and the basement will flood.
