Sump Pump Failure Playbook A straightforward response plan when the pump stops working and basement water starts building. Why timing matters: Sump pump failures often happen during heavy rain or a power interruption—the same conditions when a basement is most vulnerable to flooding. Focus first on safety, then on the cause of the failure and water removal.
1. Check What Failed Power loss A storm-related outage can stop the pump when it is needed most.
Float switch A stuck or blocked float can prevent the pump from starting normally.
Clogged intake Debris or an obstruction can interfere with the pump's ability to move water.
Pump age The HearthDry guide notes a typical sump-pump life of about 7–10 years.
2. A Simple Troubleshooting Pass ■
1. Check the power Confirm the pump has power and that the outlet or circuit has not been interrupted.
■
2. Look at the float Make sure the float can move freely and is not caught against the pit, pump or other equipment.
■
3. Check the intake Look for an obvious obstruction that could stop water from entering or moving through the pump.
■
4. Consider the pump's age If the pump is older or has shown repeated problems, replacement may be more appropriate than repeated resets.

When the Basement Is Already Wet Fixing the pump is only part of the response. The water damage still needs to be addressed.
3. Handle the Water-Damage Side ■
A. Protect yourself first If water could have reached electrical equipment, do not enter the area until it is safe.
■
B. Document the situation Photograph the water level, affected materials and the sump-pump setup before major cleanup when practical.
■
C. Remove standing water safely Use an appropriate extraction method for the water condition and the situation. Do not use a household vacuum for standing water.
■
D. Dry beyond the surface Water can remain in flooring, walls and other materials after the visible water is gone. Moisture assessment helps identify what still needs attention.
4. Reduce the Chance of a Repeat Backup protection The HearthDry guide highlights a battery backup pump as an additional layer of protection when the primary pump cannot operate.
Keep the pit accessible A crowded or obstructed sump area makes inspection and troubleshooting harder.
Know the discharge path Understand where the pump sends water and watch for obvious discharge problems.
Check before storm season A quick inspection is easier before the next heavy-rain event than during an active flood.
Know the warning signs Repeated cycling, unusual noises or a pump that struggles to keep up can be reasons to investigate.
Keep records If the pump has been replaced or serviced, keep the date and any relevant model or service information.
Practical takeaway: If the pump failed during a storm, do not stop at replacing the pump. Work out why it failed, address the water already inside the basement, and consider backup protection for the next outage or heavy-rain event.
