Installation Instructions
INSTALLATION D:
CONNECTION TO EXISTING DISCHARGE PIPE
FOR NARROW SUMP PITS
(Diagram D)
Depending on your installation requirements, PVC
pipe lengths will vary. Cut the pipes and assemble
them as shown in photo #8. 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.
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 one (1) foot above the floor. Prime and
cement it to the 1½” pipe adapter, then screw
the adapter into the pump.
5. Install a check valve on the top of the PVC
pipe attached to the Pro Series pump. Make
sure it is installed with the arrow pointing up
or it will not prevent the backflow of water.
6. When a check valve is used, a 1/8” hole
must be drilled in the PVC pipe above the
Pro Series 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 above the pump, an air lock may
prevent the pump from operating.
7. 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 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.
8. Connect a piece of 1½” PVC pipe above the
check valve of the Pro Series 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.
9. Prime and cement all pipe connections
securely to prevent leaking, and tighten all
the hose clamps.
