Pump & Pipe
Installation Instructions
(Hookup to Existing Storm Sewer)
METHOD Bb:
HOOKUP TO AN EXISTING STORM SEWER LINE
FOR NARROW SUMP PITS
(Diagram Bb)
1. Attach the “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 fl oat
switch on the main pump.
2. (a) Remove the black bottom strainer of the back-up 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 #8-32 x 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 1-1/4” rigid PVC pipe and
cement it to the threaded fi tting that is attached to the
elbow on the pump.
4. (a) Install a check valve on the PVC pipe on the back-up
sump pump. (b) IMPORTANT: WHEN A CHECK VALVE
IS USED, DRILL A 1/8” HOLE IN THE 1-1/4” PVC PIPE
THREE INCHES (3”) ABOVE THE CONNECTION TO
THE BACK-UP SUMP PUMP. Drill the hole at a 45°
angle toward the bottom of the sump to avoid splashing
water outside the sump pit.
5. If there is no check valve on 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 back-up sump 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.
