Installation Instructions
INSTALLATION B:
CONNECTION TO AN EXISTING DISCHARGE PIPE
(Diagram B)
Depending on your installation requirements,
PVC pipe lengths will vary. Cut the pipes and
assemble them as shown in photo #7. Do not
cement them together until you are sure they are
cut to the correct lengths. It is important to keep
the discharge pipes on both pumps parallel to
each other, so that the pumps remain flat on the
floor of the sump. More detailed instructions
follow.
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. Cut a piece of 1½" rigid PVC pipe long enough
to reach from the bottom of the sump pit to
one (1) foot above the floor. Prime and
cement it to the 1½" pipe adapter, then screw
the adapter into the pump.
2. Install a check valve on the top of 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.
CAUTION
3. When a check valve is used, a 1/8" hole

must be drilled in the PVC pipe above the
Basement Watchdog pump. Make sure it is
above the water line and below the check
valve. 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 in the pipe above the pump,
an air lock may prevent the pump from
operating, and the basement will flood.
4. If there is no check valve on the discharge
pipe of the main AC pump, one must be
installed at this time. Cut the discharge pipe
approximately one (1) foot above the floor.
Install a check valve on the top of the pipe
and tighten the bottom hose clamp. Now
prime and cement a small piece of 1½" PVC
pipe to the bottom of a "Y" connector. Prime
and cement the top of the "Y" assembly to the
discharge pipe with the "Y" extension facing
down toward the backup pump. Now connect
the bottom of the assembly to the check valve
and tighten the hose clamp.
5. 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.
6. Place the pump with the PVC pipe attachment
on the bottom of the sump floor next to the
main AC pump. The pumps should not touch
each other. 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.

7. Connect a piece of 1½" PVC pipe above
the check valve of the Basement
Watchdog pump, and attach a 45°
elbow to that pipe. Extend another
piece of pipe to reach from the 45°
elbow to the "Y" connector on the
other pipe.
8. Prime and cement all pipe connections
securely to prevent leaking, and
tighten all the hose clamps.
