Sump pumps should remove groundwater before flooding occurs, helping avoid issues like flooded basements. While some problems aren’t evident until the damage is already done, there are signs to be aware of to prevent flooding. Pay attention to your pump and address any of the following issues before they become serious problems.

How to Know When Your Sump Pump is Failing

1. Standing Water

If your pump appears to be working, but standing water continues to rise, you may have a clogged inlet screen that should be inspected by a sump pump technician.

2. Slow Running Pump

3. An Empty Basin

If your pump keeps running even after the basin has been cleared of water, it could indicate a stuck or broken float switch.

4. A Full Basin

A full basin should trigger the pump to turn on. A failure to do so could indicate a worn motor or a problem with the float switch.

5. Water Flowing Back into Basin

Water should never flow back into the basin once it’s been removed. If this is occurring, there may be a defective check valve. When water flows back into the basin, the pump reactivates to remove the water, and this causes the pump to cycle on and off continuously.
