Pump & Pipe
Installation Instructions
INSTALLATION B:
CONNECTION TO AN EXISTING DISCHARGE
PIPE (Diagram B)
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. (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.
2. (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
1/8” hole is not drilled above the pump, an
air lock may prevent the pump from
operating, and the basement will flood.
3. 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.
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. 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.
6. 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.
7. Cement or clamp all connections securely to
prevent leaking.
