Maintenance Check List
Maintenance should be performed 1-2 times per year.
1. Remove all debris from the bottom of the pit and the
pump strainer.
2. Remove all debris floating in the water.
3. Remove all debris from the float switch and lift rod.
4. Remove all debris around the air bleed hole.
5. Fill the pit with water. Make sure pump turns on at
the intended level.
6. While the pump is running, make sure pump is
evacuating water at a good pace.
7. While the pump is running, make sure a stream of
water is escaping from the air bleed hole. If not,
clear the hole of any deposits or debris.

The pump will not start or run
Thermal protector tripping or

If the above solutions do not solve the problem, contact Glentronics customer service 800-991-0466, option 3.
Backup Installation
When the power goes out, the Basement Watchdog AC
sump pumps will not operate. For protection during a
power outage, a Basement Watchdog battery backup
system can be installed. There are three systems with
matching batteries that will provide protection.
The illustration at right is an example of a typical
battery backup installation.
Pump is not plugged in
Water is not high enough to activate the pump
Open circuit
Poor power source
Low voltage
Bad power cable
Locked impeller
Defective float switch
Defective pump
Locked impeller
Incorrect power supply
Overburdened due to heavy sand content in the water
Pump running continuously with no water present
Float stops are positioned too close together
Water flowing back from pipe
Clogged or frozen discharge
Blocked intake
Float switch is obstructed and can not drop down
Check valve installed with no air bleed hole in
pipe or pump
Check valve is stuck or installed upside down
Check valve on secondary pump will not close
and water re-circulates within the system
Partially blocked impeller
Clogged or frozen discharge
Broken or leaking pipe
Low power voltage
Check valve installed with no air bleed hole in
pipe or pump
Check valve is stuck or installed upside down
Pump is air locked
Check valve on secondary pump will not close
and water re-circulates within the system
Blocked intake
Broken impeller
