Installation Instructions
INSTALLATION C:
DIRECT DISCHARGE TO THE OUTSIDE OF THE
BUILDING FOR NARROW SUMP PITS
(Diagram C)
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. Attach a union or check valve to the top of
the 1½” PVC pipe. This will allow the pump
to be removed easily, should the need arise.
The path of the rest of the pipe and the details
of each installation will vary. Using sound
plumbing practices, route the discharge pipe to
an exterior wall via the shortest path with the
fewest turns. More turns will reduce the
pumping capacity. The pipe section exiting the
building should be on a downward slope so that
the water in the pipe will exit outside instead of
returning to the sump pit. Be sure to seal the
hole in the wall where the pipe exits, and prime
and cement or clamp all connections securely to
prevent leaking. (No check valve is needed with
this method of installation as long as you use less
than 20 feet of pipe.)
If you use more than a total of 20 feet of pipe
in the installation (including vertical and
horizontal runs), install a check valve in place
of the union. Make sure it is installed with
the arrow pointing up or it will not prevent
the backflow of water. When a check valve is
used, a 1/8” hole must be drilled in the PVC
pipe above the Pro Series pump. Drill the
hole at a 45° angle toward the bottom of the
sump to avoid splashing water outside the
sump pit. Make sure the hole is above the
water line, and below the check valve. If a
hole is not drilled above the pump, an air lock
may prevent the pump from operating.
