Sometimes the battery backup sump pump mechanically fails and simple won’t run anymore. Our article “ Backup Sump Pump Alarm Keeps Beeping (Fixes)” goes in depth about diagnosing and fixing alarm issues, with a section devoted to diagnosing if the battery needs to be replaced or not.

If it’s less than that, the battery no longer holds a full charge and needs to be replaced. When unplugged from the trickle charger, it should read between 12.3 and 13.2 volts.
Check the voltage between the battery’s positive and negative terminals using a multimeter. (For example, see page 8 of Basement Watchdog instructions.) Maintain the proper level of distilled water in each battery cell (not applicable to more expensive maintenance-free batteries). Clean off any corrosion, as this will prevent a proper connection and possibly keep your pump from running. Make sure the red wire is attached to the positive terminal and black to the negative. However, if it has been charging and yet still doesn’t have enough power to run the pump, you need to investigate further. If you’ve lost power and your battery backup has been running recently, the battery may simply be depleted and needs time to recharge. Dead Batteryīackup sump pump battery with connectionsīackup sump pump batteries have a limited life, although improper maintenance can drastically reduce how long it lasts. If both your primary and backup use the same discharge pipe and it becomes clogged, that can quickly flood your basement (read more about the benefits of independent discharge pipes here). You can also use an independent discharge pipe separate from the primary sump pump. Regularly monitor the discharge pipe to ensure there is no blockage. We have also seen times when the end of a discharge pipe is underwater, which will also impede flow out of the pipe and reduce pumping rates. 
This can be caused by mud, stones, or even frozen water during the winter. Blocked Discharge PipeĪnother common problem is partial or complete blockage of the discharge pipe leading out of the house. It’s a good idea to check for blockage a couple times a year as a general maintenance practice.
If the strainer or impellor is blocked, this could significantly reduce pumping rates or completely prevent your pump from running. Clear off debris from pump strainer leading into the pump’s impellor. Remove the backup sump pump from the sump pit to clean it. If the switch is working, there may be either a blockage around the pump strainer or debris clogging the pump impeller.
