Pump & Pipe
Installation Instructions
INSTALLATION C:
DIRECT DISCHARGE TO THE OUTSIDE OF THE
BUILDING FOR NARROW SUMP PITS
(Diagram C)
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. Attach an “L” bracket to the discharge pipe of
the main AC pump with two (2) stainless
steel hose clamps. Position the bracket so
the bottom of the “L” is just above the top of
the main pump, and out of the way of any
float switch on the main pump.
2. (a) Remove the black bottom strainer of the
pump by pressing in the two tabs on the
strainer. There are holes suitable for
mounting on the bottom of the strainer. (b)
Using a #8-32 x 3/4” stainless screw, washer
& nut, attach the strainer to the “L” bracket.
(c) Once the strainer is attached, simply press
the pump body onto the mounted strainer.
3. Cut a three-foot (3’) piece of 1
1
⁄2” rigid PVC
pipe and cement it to the pipe adapter that
is attached to the elbow on the pump.
4. 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.
5. 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.

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.
