How do you prevent a repeat?
How do you prevent the next failure?
Test the pump each spring by filling the pit, replace pumps around the end of their typical life, and add a battery backup or water-powered backup where power outages come with storms. A high-water alarm gives early warning.
Why do sump pumps fail?
Most failures fall into a few causes, and several are preventable:
- Power: a tripped breaker or GFCI outlet, or an outage during a storm
- Stuck float or switch, often from the float catching on the pit wall or cord
- Clogged intake or a pit full of silt
- Frozen or crushed discharge line outside
- Worn-out motor, typically after many years of cycling
- Undersized pump that can't keep up with heavy inflow
What should you do before the next storm?
Test the pump each spring before the thaw: pour water into the pit until the float lifts and confirm the pump empties it. Make sure the discharge runs well away from the foundation and isn't frozen. If the basement is finished or the pump runs often, a battery backup pump covers power outages, which tend to happen during the same storms that bring the most water.
Call a professional if
- Water is near the electrical panel, furnace, water heater or outlets: don't enter, call
- The pump runs but water keeps rising
- Sewage or a sewer smell is coming up with the water
- A basement wall is cracking or pushing inward under water pressure
