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 the “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
and 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. (a) Install a check valve on the PVC pipe
attached to the Basement Watchdog pump.
Make sure it is installed with the arrow
pointing up or it will not prevent the backflow
of water.
4. (b) When a check valve is used, drill a 1/8”
hole in the 1
1
⁄2” PVC pipe three inches (3”)
above the connection to the Basement
Watchdog pump. Drill the hole at a 45º angle
toward the bottom of the sump to avoid
splashing water outside the sump pit. If a hole
is not drilled above the pump, an air lock may
prevent the pump from operating, and the
basement will flood.
5. If there is no check valve on the main AC
pump, one must be installed at this time.
Then install a “Y” connector above the check
valve on the discharge pipe for the main AC
pump.
6. Secure the pump wire so that the plug on the
end will not fall into the sump. Attach the
wire to the pipe with tape.
7. Connect a 1
1
⁄2” diameter discharge pipe above
the check valve of the Basement Watchdog
pump, and attach a 45º elbow to that pipe.
Extend another piece of pipe to reach the “Y”
connector you have inserted above the check
valve on the discharge pipe of the main
pump.
8. Cement or clamp all connections securely to
prevent leaking.
