REPLACING THE PRIMARY PUMP
Before you begin this process you will need a
new AC pump. You may also want to change the
check valves at this
time. The backup
pump uses a 1-1/4”
check valve, the
primary pump uses
a 1-1/2” check
valve. (See parts
list on page 13.)
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 of 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.
REFER TO THE PHOTOS BELOW
1. Unplug the primary pump from the blue
controller.
2. Remove the charger plug from the back of the
black controller.
3. Unplug the backup pump from the back of the
black controller.
4. Remove the sensor from the battery.
5. Remove the battery wires from the battery
terminals.
Be sure they do not touch each
other while one is connected to the
battery.
6. Slowly loosen the rubber union 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 rubber union is
loosened.
7. Separate the pump assembly from the rubber
union and lift it out of the sump by the
handle on the primary pump.
8. Turn the assembly up side down over the
sump pit to allow the remaining water in the
system to drain.
9. Loosen the hose clamp on the caged float
switch and remove the float switch.
10. Cut the cable ties on the backup float switch
and remove it.
11. Loosen the hose clamp on the top of the no-
hub connector on the primary pump.
12. Loosen the hose clamp on the top of the no-
hub connector on the backup pump.
13. Remove the Y-connector.
14. Unscrew the primary pump check valve.
15. Carefully slide the backup pump and bracket
out of the handle of the primary pump. Now
reverse the process.
16. Carefully slide the backup pump and bracket
into the handle of the new primary pump.
17. Screw in the check valve on the top of the
primary pump. (You can use the existing
check valve, or preferably replace it with a
new one.)
18. Connect the Y-connector to the top of the
check valve with the no-hub connector and
tighten the hose clamp.
19. Connect the backup pump to the other side
of the Y-connector with the other no-hub
connector.
20. Replace the caged float switch by tightening
it with its hose clamp.
21. Replace the backup pump float switch using 2
new cable ties. Make sure the float moves
easily, and will not get hung up on the pump.
22. Lower the pump back into the pit by the
handle on the primary pump.
23. Connect the top of the system to the rubber
union and tighten the hose clamp.
24. Connect the battery cables to the battery
terminals, BLACK to the NEGATIVE (-) post,
and RED to the POSITIVE (+) post.
25. Insert the fluid sensor into the top of the
battery.
26. Plug the backup pump into the back of the
black controller.
27. Plug the charger into the back of the black
controller.
28. Plug the primary pump into the blue
controller.

Power
There are several causes for power failure. The
most common is a power outage by your electric
company. During this emergency, the Basement
Watchdog system will automatically switch to
battery power and protect your basement from
flooding.
You can silence the “Power” alarm for 24 hours
by pressing the YELLOW button for 5 seconds.
The alarm will be silenced, but the light will stay
on. The system will continue to operate while
the power alarm is silenced. After 24 hours, the
alarm will reset automatically.
1. If the power is on in the rest of the house,
check the home circuit breaker or fuse box for
failure, and correct the problem.
2. Check the charger. Make sure it is securely
plugged into the wall outlet. Make sure the
power outlet is working.
3. Check the charger plug that fits into the rear
panel of the control unit. Make sure it is
securely plugged into the control unit.
The control unit must receive 115 volts AC +/-
5% from the AC outlet. Any voltage lower than
110 volts will activate the power failure alarm.
Lower voltages can be caused by utility company
brown outs or a heavy power draw from other
appliances on the same circuit. Reduce the
number of appliances on the circuit.
If all the connections are secure and the wall
outlet is operating, but the “Power” warning
light is still on, replace the charger unit with the
Basement Watchdog part number 1015001 from
Glentronics at 800-991-0466, option #3.
