Pump & Pipe
Installation Instructions
(Hookup to Existing Storm Sewer)
If the direct discharge method (Method A) is not possible,
the Barnes Battery Backup System can be hooked up to the
same storm sewer Iine as your AC sump pump by installing a
“Y” connector and two check valves.
Check your local plumbing codes. Some
municipalities prohibit the discharge of sump
water into the sewer system.
If you have a sump pit wide enough to place the backup
pump next to the main pump, use Method B. If your sump
pit is too narrow, the pump may be mounted above the main
pump. In this instance use the instructions for Method Bb.
METHOD B:
HOOKUP TO AN EXISTING STORM SEWER LINE
FOR WIDE SUMP PITS
(Diagram B)
1. Cut a four foot (4’) 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.
2. (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.
3. 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.
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. Place the pump with the 4’ PVC pipe attachment on the
bottom of the sump fl oor, next to the main AC pump.
Do not mount the pump to any existing pipes. It
should be placed on the fl oor of the sump. A brick may
be placed under the pump if there are rocks or other
debris on the sump fl oor.
6. 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.
7. Cement or clamp all connections securely to prevent
leaking.
