DIRECT DISCHARGE TO THE OUTSIDE OF THE

! 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. 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 and pushing down. There are holes
suitable for mounting on the bottom of the
strainer. (b) Using the #8-32 x ¾" stainless
screw, washer and nut, attach the strainer to

the "L" bracket. (c) Once the strainer is
attached, simply press the rest of the pump
onto the mounted strainer.
3. 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.
4. Cut a piece of 1½" rigid PVC pipe long enough
to reach from the elbow of the backup pump
to (1) foot above the floor. Prime and cement
it to the 1½" pipe adapter, then screw the
adapter into the pump.
5. Attach a union or check valve to the top of
the 1½" PVC 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.
