Pump & Pipe
Installation Instructions
(Direct Discharge to Outside)
METHOD Aa: DIRECT DISCHARGE
TO THE OUTSIDE OF THE
BUILDING FOR NARROW
SUMP PITS (Diagram Aa)
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) Us-
ing a #8-32x
3 / 4 " stainless screw,
washer & 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. 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. Attach a rubber union (sold sep-
arately) to the top of the 1 1 / 2 " 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 try to
route the discharge pipe to an exterior
wall via the shortest path with the fewest
turns.
The pipe section exiting the
building should be on a downward slope
so that the water in the pipe will exit
outside rather than return to the sump.
Extend the discharge pipe outside the
building as far as possible to avoid the
return of discharged water to the sump.
Be sure to seal the hole in the wall where
the pipe exits 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.
