Installation Instructions
(Hookup to Existing Discharge Pipe)
METHOD Bb: HOOKUP TO AN
EXISTING DISCHARGE PIPE FOR
NARROW SUMP PITS
(Diagram Bb)
1. Attach an "L" bracket to the dis-
charge 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 #8-32x
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
threaded fitting 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. (b) IMPORTANT:
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 45˚ 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 pumping.
5. If there is no check valve on the
pipe of 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 45˚ 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.
