Question and Answers


Why does the alarm on my backup sump pump go off without any problem occurring?


Check the wiring connections to make sure that they are secure. Make sure that the charger is plugged into an electrical outlet that is constantly energized and has proper voltage. Check for signs that the backup pump ran. If it did, check the main pump. If you are certain that no normal causes exist for the alarm, then it is likely that the charger will need to be replaced.
