REPLACING THE BACKUP PUMP
Before you begin this process, you will need a new
backup pump, new check valves, and new wire
ties. The check valves have a 1½” MPT on one end,
and a 1½” SLIP on the other end. See page 15 for
part numbers.

DANGER
Risk of electrical shock or battery explosion,
which can cause serious injury or death. Wear
eye protection. Work in a well-ventilated area.
DO NOT smoke or allow a spark or flame in
the vicinity of the battery. Avoid dropping
metal tools on the battery. Review the safety
instructions on page 1.
YOU WILL BE DISCONNECTING ALL THE
WIRES. BE SURE THEY DO NOT FALL INTO
THE SUMP PIT.
1. Unplug the primary pump, the blue controller,
and the power cord for the backup pump control
unit from the wall outlet.
2. Unplug the backup pump from the back of the
backup control unit.
3.
Remove the cover of the battery box and fan the
area around the top of the battery with a piece
of cardboard (or another non-metallic material)
to remove any hydrogen or oxygen gas that may
have been emitted from the battery
4. Remove the sensor from the battery, and
remove the battery wires from the battery
terminals. Be sure they DO NOT touch each
other while one is connected to the battery.
5. Slowly loosen the no hub coupling on the top
of the combination pump assembly to separate
the pipes. The water trapped in the pipe will
pour out into the sump as the no hub coupling
is loosened.
6. Separate the pump assembly from the no hub
coupling and lift it out of the sump pit by the
handle on the primary pump. Tip the assembly
over the sump pit to drain away any remaining
water.
7. Lay the pumps down and remove the two (2)
screws holding the backup pump.
8. Loosen the hose clamp holding the float switch,
cut the wire tie holding the switch, and remove
the switch from the pipe. Note its position.
9. Loosen the hose clamps on the no hub
connectors on both pumps.
10. Ease the Y-assembly o of the pumps.
11. Unscrew the pipe adapter from the backup
pump.
12. While you have the pump apart, this would
be a good time to replace the check valves.
A check valve with 1½” MPT on one end, and
1½” SLIP on the other is commonly available,
or you may order this part #1141003 from
Glentronics.
13. Now, reverse the process. Replace the pump
by first screwing the adapter assembly into
the new pump.
14. Then screw the pump to the pump stand.
15. Ease the Y-assembly back onto the check
valves, and tighten the hose clamps.
16. Install the float switch on the check valve or
on the no hub coupling with the hose clamp,
and secure the cage to the discharge pipe with
a wire tie. Make sure the floats are vertical
and the bottom of the backup float is higher
than the bottom of the primary float switch.
17. Lower the pumps into the sump pit by the
handle on the primary pump.
