In many homes the sump pump is the only thing standing between groundwater and a flooded basement. When it fails – often during a storm or power outage – the basement can fill within hours.
Signs your sump pump needs attention
- It runs constantly or cycles on and off rapidly
- Strange noises, rattling or vibration
- It is more than 7–10 years old
- Visible rust or a float that sticks
- Water in the basement even though the pump is running
- No backup pump or alarm
What a good installation includes
- A properly sized pump for your water volume (typically 1/3 to 1/2 HP for most homes)
- A sealed, lidded pit to reduce humidity and radon
- A check valve and correctly sized discharge line routed away from the foundation
- A battery backup or water-powered backup pump
- A high-water alarm

FAQ
Common questions
How long does a sump pump last?
Most last 7 to 10 years, less if they run very often.
Do I need a battery backup?
If your basement is finished, stores anything valuable, or your pump runs often, yes. Storms that cause power outages are exactly when the pump is needed most.
