Why Testing Your Sump Pump Matters in the Twin Cities
When spring hits Minneapolis and the snowmelt starts to flow, sump pumps become the unsung heroes of countless homes. One heavy rainstorm or fast thaw can push your basement to the brink—and a working sump pump often means the difference between a dry floor and a soaked disaster.
Testing your sump pump before storm season isn’t just a good idea—it’s a crucial step in protecting your home, especially in neighborhoods like Golden Valley, St. Louis Park, Hopkins, and Edina, where high water tables and older basements are common.
How to Test Your Sump Pump in 5 Easy Steps
You don’t need to be a plumber to check if your sump pump is working. Just follow these steps:
1. Check the Power
Make sure the pump is plugged in and connected to a ground fault circuit interrupter (GFCI) outlet. Reset the outlet if needed.

2. Inspect the Pit
Lift the cover off the sump pit and check for:
Standing water
Debris or silt buildup
A jammed float switch
Clean out any debris—it can clog the system or prevent the float from rising.
3. Pour in Water to Simulate a Flood
Slowly pour a bucket or two of water into the sump pit. The float should rise and trigger the pump.
If:
The pump kicks on and drains the water — it’s working ✅
Nothing happens — time to investigate ❌
4. Listen for Strange Sounds
Grinding, rattling, or buzzing sounds might mean:
A clogged impeller
A worn motor
A stuck float switch
Smooth, quick operation with minimal noise is ideal.
5. Test the Discharge Line
Head outside and make sure water is flowing away from your foundation. The discharge pipe should be clear and sloped properly. If water isn’t flowing or is backing up, there could be a blockage or freeze risk.
What If the Pump Fails the Test?
If your sump pump:
Doesn’t turn on
Runs but doesn’t pump water
Smells burnt
Is over 7–10 years old
